I-10 in Baton Rouge
CoreySamson:
re. article:
I guess it's good that a lot of the traffic on I-10 in BR is local. That seems to indicate (at least for me) that when the new Mississippi River bridge south of I-10 is built, it will take off quite a big load off of the I-10 bridge. That leaves I-10 for the cross-country traffic.

It's already 6 lanes over the river. Maybe do a little more research before asking?

6 lanes may not be enough. Maybe do a little traffic engineering?

Only on the Mississippi River Bridge section, then it drops back to 4 lanes west of LA 1.
The proposed I-10 widening would add an additional lane in either direction from the LA 415 interchange to LA 1, but would still leave the bridge intact as is.
Only way you could improve capacity on that bridge is to add another span; and that would require some serious reconstruction of both the LA 1 interchange and the approach to the I-10/I-110 Split, and prohibitive cash.
Better to build a freeway grade south bypass around Plaquemine and Gonzales, or build a north bypass using Airline Highway, an improved US 190 Mississippi River bridge (along the lines of what was done to the Huey P. Long bridge in NOLA), and a connection to I-10 west of Westport.

6 lanes wasn't enough 15 years ago. But as Anthony noted, improving that bridge location would be prohibitively expensive.
webny99:
An observation, not specific to Louisiana: when a bridge lacks or has extremely narrow shoulders, it can still be a constraint on traffic even when it has the same number of lanes as the roadway on either side. I-190 crossing the Niagara River and I-95 crossing the Susquehanna (near Havre De Grace, MD) are examples of this.
