Due to the 4 bridges in a row closed on US-90, and with a current earliest possibility of them even being replaced by 2028, I recommend adding a point at the eastern* end of the closure so people can still clinch that area partially, as you can still cross over the Pearl River bridge @ the LA/MS border into LA. The 'US190' point is within 0.5 miles of the western* closure, so I don't think an extra point on that side is necessary.
Eastern* end of the closure: 30°14'13.6"N 89°37'40.9"W
