Mathews Bridge, Cantilever road bridge in Jacksonville, Florida, United States

Mathews Bridge is a red steel cantilever bridge carrying the Arlington Expressway over the St. Johns River in Jacksonville. Its lattice truss rises into two peaks, a taller one and a shorter one, and the steelwork rests on massive grey concrete piers built as paired vertical legs. The bridge opened in 1953 and is 2,248.2 metres long.

Calls for a bridge to Arlington and the beaches grew in the early 20th century as car use rose; in 1938 the Duval County Commission ended ferry service to build support. John E. Mathews, a state legislator and later Florida Supreme Court chief justice, helped secure funding for the $11 million project, backed by bonds and toll revenues. The bridge opened on April 15, 1953, and tolls remained until 1989.

The bridge was originally silver and was repainted garnet in 1984 to mark Jacksonville's short-lived United States Football League franchise, the Jacksonville Bulls. The name honours John E. Mathews, a state legislator and Chief Justice of the Florida Supreme Court who helped secure funding. The bridge also appears in "My Generation" by Limp Bizkit, a band that started in Jacksonville.

The bridge carries traffic on the Arlington Expressway between downtown Jacksonville and Arlington, with a concrete riding surface over the center span since the 2007 deck replacement. Its charted clearance was corrected to 146 feet (45 m) after the 2013 ship collision. There is no walkway for visitors, so view it from the riverbanks.

The Mathews Bridge appears in the lyrics of "My Generation" by Limp Bizkit, a band that began in Jacksonville. Its center span was also the site of a 2013 collision: the ship USNS 1st Lt. Harry L. Martin struck the span, closing the bridge until repairs finished on October 29, 2013.
