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

Easiest reasonable thing to do to help traffic in br is to remove the majority of traffic lights on airline highway so traffic can actually move. Airline was supposed to be the bypass.

If you want more then widen the median (there is plenty of right of way) and install median u turns, maybe a single point urban interchange or 2.
