re: How would closing the washington exit help traffic?

If people would realize they can go faster than 40mph through there it would help.

That's the plan I believe. I also suspect the non yes-man engineers at DOTD are telling the Secretary and politicians to walk back their public comments that this will fix I10 traffic congestion.

What would help a ton and doesn't require any construction would be to make Port Allen truck traffic on LA1 enter I-10 at hwy 415 instead of at LA1(foot of the bridge). Those trucks get into the bridge traffic at about 20 mph. The on ramp is too steep and they cannot build any speed. It causes a huge back up in traffic everyday. Same goes for trucks entering on the BR side at Highland.

I don't think they are closing it. Just offering an alternative they hope will get used. It's ridiculous and won't help much at all. 110 should be 1 lane and 10 should get the 2. 110 gets 50,000 cars a day at that point. 10 gets 100,000 and that's double since 1997. Doesn't take a genius to know what needs to be done here. Also 110 travelers will have plenty of distance to merge and it's relatively straight and with no incline to deal with that slows the trucks. The bridge has an incline and travelers will pass slow vehicles in a choice of 2 other lanes both of which must be merged from eventually. There is also a curve to deal with and the trucks will continue to constipate the ramp causing major slow downs and many times accidents which only make matters worse. So a lane needs to be switched from 110 to 10 until a permanent fix can be implemented.
