Fayose bridge is not up to 2klm .

It's actually 1.2klm.


The bridge so far looks solid and credible, though I don't see any serious traffic situation to justify the bridge and pointless waste, apart from see mee too syndrome.

Leave engineering to engineers.

The under pass is already a dual carriageway but the challenge is that the road has too many access roads and properties that access the road directly. This will constantly cause traffic jams and increase travel time.

If they plan the road wider, a lot of properties will be affected and it doesn't make the access roads disappear. The problem just reduces but will not disappear while the expansion will gulp huge funds due to compensations and relocations.

Construction of a parallel over pass solves the problem permanently. Those who wish to access internal areas of the city need not bother about all the access traffic in the under pass and get to their destination inside the city with no traffic lights or intersections to worry about.

The main aim is time of travel.

The Flyover as a solution is actually counter intuitive from a design standpoint. The goal is to decongest traffic but what I see is just a relocation of the traffic hotspot from the center of the commercial area to the foot of the flyover.

In engineering, utility, aesthetics and safety are the three tenets and sadly this overly complex flyover meets none of these criteria convincingly. The Flyover is unnecessarily long, the space beneath it doesn't link more than one perpendicular road network i.e. eliminating roundabouts, nor is it economically viable (warehousing) due to safety concerns.

A reasonable solution is to create a 4 lane road. With, the two center lanes dedicated to commuters who have no business with the commercial area. The two other outlying lanes will go through the busy area. Each flanking the speed lanes.

Each of these four lanes will be adequately seperated by means of concrete lane guards or short width trenches (for drainage purposes if that is a concern) complemented with simple wire fences. This will automatically prevent any vehicular or human movement from one lane to another. Separation of concerns is complete.

To tackle the traffic in the busy lanes, two or three strategic locations will have pedestrian bridges (crossing the entire 4 lanes and with stairway access to the two speed lanes).They will be erected to ease human traffic out of the market and allow the people means to access the speedlanes so as to board vehicles out of the area fast. This will prevent any further traffic buildup on the busy lanes.

In case of emergencies too, you can easily access the busy lanes through the speed lanes using contraptions over the trenches and cutting through the wire fences to reach victims. There will be no need to factor in elevation contingencies as would be the case with this 2km long flyover. Now all 4 lanes will share the traffic load optimally and prevent any gridlock in the future. This solution meets the three engineering requirements adequately.

In engineering the simplest solutions are the best. Ockam's razor and yes, this flyover is not only unnecessary but sub-optimal as a solution.

plainol:
Am confused o, Engineers in the house, please won't a normal wide road do the job of that fly over.

Wide road with concrete demarcation in the middle lane will do the job of that bridge, just like Palmgrove - Maryland axis , the place will even be more beautiful and less costly

I believe this bridge madness where it is not needed is a form of stealing from government. These governors are devils hand tool in Nigeria.

It will not sir. That is where they called Sabon Gari /singa market. The fly over will ease congestion. Its a perfect plan.

The Flyover as a solution is actually counter intuitive from a design standpoint. The goal is to decongest traffic but what I see is just a relocation of the traffic hotspot from the center of the commercial area to the foot of the flyover.

Going by the pictures, we can not even see the foot of the bridge or whatever traffic you are talking about at the foot of the bridge. The bridge goes as far as the eyes can see, we can not even see the on or off ramp apart from exist for traffic heading to other parts of the city.

The bridge obviously glossed over the central market and business district area and many intersections.

In engineering, utility, aesthetics and safety are the three tenets and sadly this overly complex flyover meets none of these criteria convincingly. The Flyover is unnecessarily long, the space beneath it doesn't link more than one perpendicular road network i.e. eliminating roundabouts, nor is it economically viable (warehousing) due to safety concerns.

The bridge can in no way be too long if the idea is to move people, goods and services from one end of the city to the other end with ease and away from bustling traffic and intersections below which saves time, manpower and productive hours, reduces traffic stress, accident and ultimately money.

A reasonable solution is to create a 4 lane road. With, the two center lanes dedicated to commuters who have no business with the commercial area. The two other outlying lanes will go through the busy area. Each flanking the speed lanes


Each of these four lanes will be adequately seperated by means of concrete lane guards or short width trenches (for drainage purposes if that is a concern) complemented with simple wire fences. This will automatically prevent any vehicular or human movement from one lane to another. Separation of concerns is complete.

You are not projecting anything different from what they did apart from adding the extra lanes above in form of a flyover.

They obviously can not do what you are suggesting without bulldozing and eliminate established businesses in the area, without incurring exorbitant compensations, without relocating power and poles communication cables or poles, maybe water pipes or gas lies, possible court litigations and so on.

So, avoiding all that extra cost, time and headache mean going overhead and achieve the same goals on a better scale.


Case study::: 10 lanes Lagos Badagry expressway. Some people are asking why it's taking too long to complete the project, but news flash, the state is in court battling many business and homeowners who are refusing to relocate, demanding excessive compensations, they are dealing with power companies to relocate power lines and cables and so on.

You obviously lessen the cost, headache, time and energy by going overhead.


I'm almost 100% they saw your option, they encountered difficulties and needless cost before going overhead.

To tackle the traffic in the busy lanes, two or three strategic locations will have pedestrian bridges (crossing the entire 4 lanes and with stairway access to the two speed lanes).They will be erected to ease human traffic out of the market and allow the people means to access the speedlanes so as to board vehicles out of the area fast. This will prevent any further traffic buildup on the busy lanes.

The issue here is obviously vehicular traffic and not human traffic and you don't need a long bridge or flyover to move human traffic from one side of the road to the next.

The obvious reason is, of course, to move people, goods and services from one end of the city to the next. There's absolutely no reason to spend 1 or more hour shuttling within the city instead of 10 minutes. Time is money and the more money people and businesses make = more money for the state and the city.

In case of emergencies too, you can easily access the busy lanes through the speed lanes using contraptions over the trenches and cutting through the wire fences to reach victims. There will be no need to factor in elevation contingencies as would be the case with this 2km long flyover. Now all 4 lanes will share the traffic load optimally and prevent any gridlock in the future. This solution meets the three engineering requirements adequately.

In engineering the simplest solutions are the best. Ockam's razor and yes, this flyover is not only unnecessary but sub-optimal as a solution.

Why go through all that? If your destination and or emergency services means using the flyover to get to where you are going or the hospital, you get on it and if it's accessible down below, then use the surface roads. Simple.

This has nothing to do with engineering, this basic traffic management and the state building problem-solving infrastructure to improve quality of life, save human and productive hours, cost of duing business and pollution.

I didnt read beyond your 1st paragraph when i had an example in mind where all you have said cannot be a solution in the Nigerian context.

I do not know which city you live in but the example that comes to my mind is Deidei in Kubwa express of FCT. For those familiar with the rush hr issues, the Nigerian factor will make your solution useless.

In case you dont know Kubwa express or Deidei, Kubwa express is one of 2 biggest roads in FCT, it is a 10 lane expressway running from Asokoro to Zuba. It has 3 fast lanes and 2 service lanes each direction. Now, Deidei has a popular building materials market so a pedestrian bridge has been constructed across the road.

The main issue with Deidei is that tankers and haulage trucks park on shoulders of the service lane sometimes causing holdups. Commercial cars also avoid the service lanes due to this, preferring to drop and pick passengers on the shoulders of the fast lane. The Nigerian factor then comes in where commercial drivers hustle for passengers to the extent they park parallel to each other. This parallel parking and the constant need for each cab operator to be selfish thereby pulling out of lane from parking position just to go in front of his rival then stop again. Before you realise, they have taken 2 of the 3 lanes with cars often pulling out to the 3rd lane from parking. It is usually chaotic.

This affects multiple locations along the Kubwa express. The second problem is that ppl refuse to use the pedestrian bridges, causing accidents on the fast lane. Ppl are crushed to death almost on weekly basis.

The solution was to erect barb wire fence 200m each side of the bridge to discourage foot crossings. That reduced but did not eliminate the problem because some ppl decided to walk to the ends of fence then cross or stop a cab on the fast lane. Within a few yrs, the fence would hv been broken down by buglers hungry for steel. Thereafter, problem returns.

This is a practical example where road expansions does not provide a direct solution to traffic congestions.

Now, back to the Kano overpass, i want to suggest you look at the pictures very closely. With the number of street access from that road, even a 10lane express way will be encroached upon by hawkers, cab drivers and passengers. There are streets, warehouses, supermarkets etc directly accessing the road. The issues with the road is the number of intersections. In road design no building is supposed to access an expressway directly. The access roads are supposed to be traffic collectors. This situation in Kano cannot be achieved. It needs planning and alot of reorganizing of a very large area.

The shortest time of travel across this congested area can only be achieved by an overpass. An overpass eliminates all intersections while also restricting hawkers and the cab driver attitude of picking and dropping passengers on the highway.

Lastly, about the bolded, the road is not the cause of the commercial center, it is the commercial business (ware houses, supermarkets, office buildings which brings motor parks and hawkers). The overpass does not move away the commercial center, it provides and option to bypass it. Why would activity move to the foot of the bridge over a kilometer away with no source of commercial activities?

This same kind of fly over provided a simple solution to the congestion in Kawo Kaduna. However, the lenght was too short to be 100% effective but i will rate it 70% effective in the Kaduna situation.

trenchmonk:


Does Dangi roundabout really need a flyover? The major place in need of a flyover has already been taken care of by "gada lado" it is just a ploy to steal money as I don't think it is necessary

I think flyovers are replacing roundabouts in the 21st century.

Sadly, it appears that we are missing the vital point here. The priority in the road decongestion decision is the commercial centre and not the random traversing the bridge on a daily for obvious economic reasons. Lagos loses billions daily due to road congestion at the popular Apapa bridges. This only points to one conclusion: easing the congestion around the commercial centers is worth more to the Kano state government than allowing hassle-free commute for other road users from one end of the city to another. Suffice to say that a solution that does not cater to this goal is not a solution at all.

No, I am not suggesting a reversion to the full-blown madness that might have been commonplace in that area before the bridge came onboard but isolating the traffic around that busy area from the benefit of linking to the speed lanes at all is the real problem. In other words, controlled access is the solution, rather than a complete cut-off.
In your case concerning the Kubwa express, you alluded that human indiscipline was the bane of the expressway. It cannot be wished away and will eventually crop up even in this system. To counter it I would reference Rumuokuta bridge in Port Harcourt, where the flyover has done next to nothing to alleviate traffic.
If we look at the picture where the bridge passes over the busiest section of the commercial center (which was my focus while responding) there is a connection from the road from that point to the bridge and it isn’t far off from the busy hotspot. With the rate at which the umberella/ kiosk owners are already invading the small space left, I shudder to think about what will happen when the bridge is completed and they can blast at full power. This will mean an inevitable backlog of traffic right down to the foot of the flyover linking that area to the main bridge and even further backward. And since there is no alternative route, the situation will be very much worse than it was before but all commuters will have to wait it out before they can get to the bridge for a reprieve. Now imagine for some reason you were stuck in that kind of traffic...

Hours will be lost, goods delivered late and basically, the economic potential of that center will be depreciated appreciably. To those using the length of the bridge, of course, there is no issue, but what is their economic relevance compared to the busy center? This is why I was sure to use the word optimal. The bridge is not an optimal solution.

Allowing access to the speed lanes through pedestrian bridges will serve to depressurize the market. Human traffic is mostly the cause of vehicular traffic in many congested areas. If we allow the buyers of small handy goods a means to access the speed lane and get away from the center fast enough, the road serving those transporting heavier bigger goods will be a lot freer.

Maintaining wire fences is a lot cheaper in the long run than maintaining a bridge. Only one safety assessment can pay for kilometres of wire fence installation. One area where fence installation has proven to be effective is Ikorodu, Lagos. The problem of stubborn and unruly pedestrians can be effectively handled by law enforcement officials i.e. in Lagos.

We may disagree on the approach to tackle this issue but I think we will agree on one thing: Our cities are not properly planned.

but what's the point of that flyover is it to solve traffic congestion or what

1. The foot of the bridge I meant is the one linking the busy center to the length of the main flyover.

3. The difference is in the access of pedestrians to the speed lanes which would be next to impossible or terribly arduous with the flyover design. I am also advocating simplicity.
4. Not necessarily, the road needn’t be widened beyond reason, a lane or two extra is not going to be much of a big deal.
5. A ten lane expressway is an overkill in this case but I get your stance, although I doubt there is a need for such level of expansion on that road.

7. Human traffic slows down vehicular traffic and for the busy area this is actually a real problem as you would have more people using that zone that vehicles on a normal day. i.e. a market.

This only points to one conclusion: easing the congestion around the commercial centers is worth more to the Kano state government than allowing hassle-free commute for other road users from one end of the city to another. [This is the basis where i think we do not agree. Where is this congestion? Its in a road mind you. Congestion and hassle-free commute are like 2 sides of the same coin. The solution they have provided is not for human congestion like it was mentioned before, it is for vehicular congestion. 2 types of vehicular cummuters meet at this point, those who are there for commercial activities and those who are passing because there is no alternative road. The solution needed must separate the two. In road construction, there is no better road traffic separator that is better than flying over or under. That is the best option that was chosen for this location.] Suffice to say that a solution that does not cater to this goal is not a solution at all.

No, I am not suggesting a reversion to the full-blown madness that might have been commonplace in that area before the bridge came onboard but isolating [Best means of isolating traffic is flying over or under not concrete median as you seem to suggest] the traffic around that busy area from the benefit of linking to the speed lanes at all is the real problem. In other words, controlled access is the solution, rather than a complete cut-off. [By this comment, i think you have misunderstood the whole solution. This fly over does not lift the pre existing road off the ground and off the commercial area, no. The fly over is like an entirely new road constructed with piers in the middle section of the pre existing road leaving the old road in place. This means that there is an under pass and over pass. There are now 2 roads, the flyover and the pre existing road. This just separate the traffic, those passing should fly over, those accessing collector roads go under, those going to the formerly congested would also go under.]

[No engineer should base his design on law enforcement. A traffic light is designed to accommodate that person who eyes a green light turning to amber but accelerating to pass before the red comes on. The designer puts in anywhere between 1-5 seconds delay in between a red on the stop side and a green on the go side. In designing automatic speed tickets, tickets are not given when you pass speed limit by a small margin say 1-3km/hr above the limit. Designer considers speedometer errors in your car. Engineers consider a lot of human errors and even deliberate law breakers to an extend.]

We may disagree on the approach to tackle this issue but I think we will agree on one thing: Our cities are not properly planned.

My words in Red

onwards:


The Flyover as a solution is actually counter intuitive from a design standpoint. The goal is to decongest traffic but what I see is just a relocation of the traffic hotspot from the center of the commercial area to the foot of the flyover.

In engineering, utility, aesthetics and safety are the three tenets and sadly this overly complex flyover meets none of these criteria convincingly. The Flyover is unnecessarily long, the space beneath it doesn't link more than one perpendicular road network i.e. eliminating roundabouts, nor is it economically viable (warehousing) due to safety concerns.

A reasonable solution is to create a 4 lane road. With, the two center lanes dedicated to commuters who have no business with the commercial area. The two other outlying lanes will go through the busy area. Each flanking the speed lanes.

Each of these four lanes will be adequately seperated by means of concrete lane guards or short width trenches (for drainage purposes if that is a concern) complemented with simple wire fences. This will automatically prevent any vehicular or human movement from one lane to another. Separation of concerns is complete.

To tackle the traffic in the busy lanes, two or three strategic locations will have pedestrian bridges (crossing the entire 4 lanes and with stairway access to the two speed lanes).They will be erected to ease human traffic out of the market and allow the people means to access the speedlanes so as to board vehicles out of the area fast. This will prevent any further traffic buildup on the busy lanes.

In case of emergencies too, you can easily access the busy lanes through the speed lanes using contraptions over the trenches and cutting through the wire fences to reach victims. There will be no need to factor in elevation contingencies as would be the case with this 2km long flyover. Now all 4 lanes will share the traffic load optimally and prevent any gridlock in the future. This solution meets the three engineering requirements adequately.

In engineering the simplest solutions are the best. Ockam's razor and yes, this flyover is not only unnecessary but sub-optimal as a solution.

Have you seen the blueprint? Or just came to this long conclusion based on the above pictures?
Have you even ever being to the place and observed the nature of the traffic flow?

SO WHATS YOUR HEADACHE.

UfuomaUN:
Nigerian governors think development is about overhead bridges! Cosmetic projects to siphon funds. The only state that probably needs a bridge of this magnitude is Lagos cos of the huge vehicular traffic in that state! Why spend a lot on building a 2km bridge when cheaper alternatives exist? A state with a very high poverty rate for that matter!

Please stop displaying your ignorance. Just Hate if your going to hate, Nobody would beat you.
Some states also have traffic hold ups and Jams in Certain places and at particular times. Travel round and Don't just stay glued to Lagos.
And fyi, Kano has the 7th Highest IGR & 6th Highest GDP in Nigeria. And the Largest Commercial city up North. Google is there to help you.
And lots of your brothers are there making it big.

No offense, I don't see any meaning, logic or relevance in your argument. I'll pass.

UfuomaUN:
Nigerian governors think development is about overhead bridges! Cosmetic projects to siphon funds. The only state that probably needs a bridge of this magnitude is Lagos cos of the huge vehicular traffic in that state! Why spend a lot on building a 2km bridge when cheaper alternatives exist? A state with a very high poverty rate for that matter!

Kano is a poor state according to your ignorant conclusion, but the same poor Kano built and commissioned better quality projects than the whole of your region combined.


All you people do is spew rubbish and needless insult and put other people down, but your own leaders re so corrupt and incompetent that you can not even show us anything meaningful they did with your taxes, allocations and derivations, it's like your own useless leaders are invisible to you, but leaders and people in other states are always visible to bad mouth and insult.

This fly over does not lift the pre existing road off the ground and off the commercial area, no. The fly over is like an entirely new road constructed with piers in the middle section of the pre existing road leaving the old road in place. This means that there is an under pass and over pass.

My words in Red

If there were an underpass and overpass, we wouldn't be debating this design.

Actually, the flyover DOES lift the preexisting road off the ground and away from the commercial centre. At least going by the pictures presented in this thread. The bridge is supported by two piers per section and not one central pier, the old road is effectively eliminated I'm afraid. I attached a photo for clarity purposes.

That's fine too.

Going by the same pictures, the bridge sits in and consumed just the middle lane with rooms left on the right and left sides of the bridge for vehicular traffic below.

Are we not looking at cars moving on both sides of the bridge in the other pictures?

We are saying the same thing. It is effectively a 4 lane highway but the center lanes are now converted to a flyover.

These two post of yours do not agree with each other.

There are so many cars in the pictures and so many intersections which have obviously been under the flyover.

Honestly, you're so un intelligent and daft I have to ignore you!

Please stop displaying your ignorance. Just Hate if your going to hate, Nobody would beat you.
Some states also have traffic hold ups and Jams in Certain places and at particular times. Travel round and Don't just stay glued to Lagos.
And fyi, Kano has the 7th Highest IGR & 6th Highest GDP in Nigeria. And the Largest Commercial city up North. Google is there to help you.
And lots of your brothers are there making it big.

I don't have brothers in Kano

They are doing great things in Kano for sure. These are solid first projects

And,according to you,theres nothing to show in Ekiti cos the brave Fayose is Pdp. Equally nothing to show in Ondo cos Mimiko was there. Typical of betrayers and descendants of that olt time runaway ilorin weak paper warrior,a..ja

You said the road is effectively eliminated, but it's not, the center lane was elevated to allow and move traffic heading to other parts of the city sidetrack the congestion and intersections down below, but they still have underpass/extra lanes for vehicular traffic down below.
