They do typically suspend tolls during mandatory evacuations (health and safety), but I am not aware of any rule stating that they couldn't make 331 a toll road. If my memory is correct, they had a group come in and explain how it could likely be built sooner if it was made a toll road.
I thought I remember it being suspended after a storm too - I was in town, which means everyone was back from any evacuation as I really err on the side of caution w/ storms.

Hope someone lets us know when they plan on moving that unexploded ordinance. I may make a timed trial run up already four-laned 79 across already four-laned West Bay Bridge next time I head up to NoWal from SoWal. I'll have to decide whether I want to cut back all the way on 20 to new 331 bypass in Freeport or take 81 and other scenic backroads in to town. Any plans for a toll on that bridge? Until the new Panama City - Bay County airport opens near West Bay, traffic should be easy. Miles may be more, but time may be better with construction delays. I've been wanting to make that trip again anyway.
