re: West side Expressway with new bridge ( aka Loop) gaining traction

I think the best plan would be a northern loop that goes from around Denham to meet up with Airline near Plank Road. At that point, Airline is a controlled Access highway all the way until 190 crosses the Old Bridge. From then on, you just build a span to connect 190 to I-10 right past Lobdell.

On the Southern end, create the Westbank Expressway along Highway 1, then 4 lane with turn lanes Highways 30, 73, 74, and 70 through Ascension and Iberville Parishes and put a new bridge in St. Gabriel where 74 hits River Road, then add I-10 interchanges at 74 and Bluff Road.
