re: Looks like after the 5 year I-10 widening project is done, traffic times will improve 2%

I don’t believe that.

If they can fix the angles and lack of shoulders - they will cut accidents significantly and reduce traffic tie ups.

I noticed in the layout plans that they are adding an additional lane but are making the deck wide enough to add another later. No point in doing that now until they figure out how to widen the bridge.
