I remember the bridge at Chester IL as being unpleasant with a poor surface, no shoulder, lots of traffic, bad expansion joints, and so on. It was a wait for a lull in traffic, take the lane, and make a fast run for it kind of situation. Far from ideal and probably many folks nightmare stuff, but it didn't scar me for life or anything.
I forget what the bridge was like at Baton Rouge, so it must not have been too bad. I think it had a nice shoulder, but my recollection is hazy.
