E. L. Patton Yukon River Bridge, Road bridge in Yukon-Koyukuk Census Area, United States.

The E. L. Patton Yukon River Bridge is a girder bridge 2,295 feet (700 m) long and 30 feet (9.1 m) wide, carrying the Dalton Highway and the Alaska Pipeline across the Yukon River. Its driving surface is timber, laid on a steel deck attached to a pair of steel box girders. The span rises about 200 feet (61 m) above the river and changes length by nearly 2 feet (0.61 m) between summer and winter.

Construction of this bridge began in 1974 and was delayed by setbacks with foundation work before opening to traffic in 1975. The project was tied to the development of oil resources in northern Alaska and the expansion of infrastructure along the Dalton Highway.

The bridge is named for Edward Patton, who was president of the Alyeska Pipeline Service Company during the pipeline's construction; the state gave it his name in March 1982. Until the pipeline was finished, Alyeska controlled the span, and the haul road and bridge passed to state control in October 1978 after debate and litigation over who could use them.

This bridge is part of the Dalton Highway serving traffic traveling to northern Alaska. Because of its remote location, visitors should be prepared for harsh conditions and carry adequate fuel and supplies.

The bridge deck is timber laid over a steel deck on two steel box girders, and the wooden surface has been replaced four times: in 1981, 1992, 1999 and 2007. Its length also changes by nearly 2 feet (0.61 m) between summer and winter.
