I work in the tech park area off Florida but live off of hwy 42 in prairieville close to hwy42/hwy44. From my perspective (concerning daily commute) the biggest problem I face is Hwy 42 itself, Airline from Hwy 42 to Highland, and finally Airline Hwy around Parkview Baptist. These are the specifics of those problems.
Hwy 42 from LA44 to Airline needs to be widened. This project is going to be started this fall with utility moves and then next summer they will start the road work. We are looking at probably a late 2016 or early 2017 completion date at best. The only fix is to add capacity (driving lanes) and turn lanes. At least this is being addressed. The second part is the school busses run during all parts of the morning. I've seen them out at 630 and I've seen them out at 730.
Airline Hwy from LA42 to Highland. The true problem here starts with the light at LA73 in Prairieville. The issue is simple, they need more driving lanes. DOTD reworked the intersection at LA42 to include Jturns. I will say that it has helped traffic on 42 but made the problem on Airline worse. I still am curious as to what the effects will be when school starts. Between LA42 and Old Perkins the road is already widened however since it's only a mile they have it stripped as turn lanes. The other main issue with this part of the road is Highland. They have to make the light sequence stay green long enough to help highland out between LA73 and Airline. It's a short distance of about half a mile however it's a three lane road (1 each direction + 1 center turn lane). This road stacks very badly so the light for them stays green longer then it should causing traffic to backup on Airline. I know DOTD will never put an overpass here but it would be the best outcome. They also should and hopefully will add an extra driving lane to this short segment of highland.
Airline Hwy around Parkview is just a matter of two-four laned roads merging into each other with only two continuous lanes. They need to have airline be 4 lanes for the stretch of road that is shared with HWY73. Northbound is almost always stacked morning and evening. The southbound left turn lanes onto Jefferson have a very long green light (which it needs) but this causes the north bound lanes to stack.
My wife and I for our next house are considering moving back to EBR just to avoid 1 & 2. There are still good areas in EBR and our low satisfaction primarily stems from traffic and lack of planning in Ascension parish. The only thing that keeps us is the fact that Ascension has really good schools. Livingston also has decent schools so we may decide to move a little further north but I don't think in 2 years we will be living in Ascension parish. I know several of our neighbors are very unhappy with the area and would move back to EBR if it weren't for the schools. Some have said screw it and moved anyway and are paying for private school if they can afford to.
