US Highway 98 runs along much of the U.S. Gulf Coast. between Mobile, Alabama, and crystal River, Florida. It goes through Panama City and Panama City Beach. and really stretches out along the Florida Panhandle.
There are quite a few nice long bridges as well, including the one east of Apalachicola and the Hathaway bridge over St. Andrew's Bay connecting PC and PCB. It is called 3,358 feet long and referred to as the Panama City Beach Parkway.
