What) The Pensacola Bay Bridge, also known locally as the Three-Mile Bridge, runs between downtown Pensacola and Gulf Breeze. It carries four lanes of U.S. Highway 98 across Pensacola Bay. The bridge opened to traffic on October 31, 1960, at which time it replaced the Thomas A. Johnson Bridge, a narrow two-lanestructure that ran parallel just to the east. The decommissioned original bridge served as two 1.5-mile-long fishing piers until they were largely destroyed by Hurricane Ivan in 2004.

    In 1989, the bridge was struck by a barge and was out of service for several months. All traffic was diverted to ferries, causing severe backups in both Gulf Breeze and downtown Pensacola. In January 2010, as the bridge neared the end of it's 50-year design life, the Florida Department of Transportation announced that the bridge was structurally deficient and would have to be replaced within six years.

    Why) We drove across many bridges during this trip and I took pictures while crossing most of them (especially when I wasn't driving).  You only have to look at the ones with some artistic merit.
