Nigerian ‘analysts’ will take the cost of a road or railway & divide by length & jump to ridiculous conclusions. Without accounting for number of lanes/tracks, topography, compensation, accompanying infra (bridges), etc.
It’s a very illiterate thing to do. Stop it!

Look at the Abuja-Kaduna Rail vs the Lagos Ibadan Rail, for example.
ABJKD = 186km of SINGLE track.
LAGIB = 158km of DOUBLE track = 158 X 2 for actual (main) track length = >300km.
Surely common sense should tell you to factor all these in before comparing relative costs?

Also, for example, its a given that, on ‘like for like’ basis, road projects in the swampy terrains of the Niger Delta tend to cost more than in drier terrain of the North.
Read Julius Berger’ notes about building the Bodo-Bonny Bridges/Road - “the most difficult of terrains…”

All of these variables must be sensibly kept in mind when you’re trying to compare different projects. You can’t just take cost and divide by length/distance, and think you’re making any sense.
Also, compensation and utility relocation costs can be quite significant depending on location. What you’ll pay in Lagos will be way above what you’ll pay in Ondo for example. 20+km of LAGIB rail runs thru built-up Lagos. Imagine the cost of relocating utilities + compensation.
That cost of doing rail in built-up Lagos will definitely not be the same cost when you leave the Lagos metropolis and enter the much less densely populated areas like Kajola and Papalanto.
You must factor all these into your ‘analysis’, or risk coming off as ignorant.

Some Road projects have bridge components, just as Some Bridge projects have road components. Like Bodo-Bonny that is 3 main bridges and several minor ones, and 30+km of Highway, or Second Niger Bridge that is 1 major bridge + 2 minor bridges + 10km of highway.
Context matters.

“So, we have to design an additional lane on both sides comprising of 365 kilometers each way and we have to also make a new design for about 66 bridges across the entire length...” vanguardngr.com/2020/02/fec-ap…
