re: Proposed and Conceptual Interstate Corridors in Louisiana

While I see the merits to both sides of the I-49 ICC in Shreveport it may come down to money. If you connect the 2 parts of I-49 you only have to build a 3 mile stretch of interstate.

However if you decide to "Loop it" and convert 3132 and 220 into thru interstate road as now I-49, it will take more than just throwing up new signs. The current roadway would need to be expanded and that would mean a whole new cloverleaf at I-20, something would have to be done about the nearly 90 degree curve on eastbound 220 at I-20, as well as a new bridge over Cross Lake.

In the end, money may determine the outcome.

In the end, this is what they have to work through. That is why I think if they built the interstate through that area, it would need to be below grade. Keep/reconnect the established street grid and let the freeway be secondary.

Something like this (proposed in Birmingham)




Essentially, that is also what is going to need to happen in BR, at some point in the future. You know, once they fix the existing infrastructure we do have (new bridge, expansion of existing interstate, etc).
