Nigeria;second World Largest Deposit Of Bitumen,world Greatest In Road Potholes

i have travelled various road networks in Nigeria, i found out that some are not worthy to be called a road,but a death trap,tyre punchers,some potholes are even six feet deep,worst hit is okigwe- Enugu road.
It was once said we got the second largest bitumen deposit in the world. we dont have good road,police are busy asking of "road worthiness certificate" from motorist, pls i want somebody to post a model of a standard road for me,im tired of this road patching engineers that parades themselves as construction companies in nigeria,pls take a look at that picture that is welcome to portharcourt,
