Theres only 2 ways to get from the east to the west. I10 across the atchafalaya basin bridge, (fun fact, when built it was the 2nd longest bridge in the US). or HWY 190 which goes around but cuts thru a bunch of small towns. Yes watch for cops. The speed limit on the basin bridge is 55 for trucks and 65 for cars, but speeding is common, which is why you'll see State Troopers often. Any wreck will close the bridge forcing everyone to bypass on 190 and it creates a ridiculous mess. And then lets not forget about baton rouge traffic in general. IT SUCKS. Where I10 and I110 merge its the only place in the US where the interstate is 1 lane. If you have to come thru, best times is at night, or super early, Avoid the rush hours at all cost.
