State Route 263 (SR 263, also known as Devils Canyon Road) is a 9.24-mile (14.87 km) long state highway in the U.S. state of Washington, serving rural Franklin County and the Lower Monumental Dam. The highway begins at the Port of Windust on the Snake River and travels east to the Lower Monumental Dam and north to SR 260 in Kahlotus, paralleling the Columbia Plateau Trail. Devils Canyon carried traffic on the Spokane, Portland and Seattle Railway in the early 20th century before the completion of a road serving the Lower Monumental Dam in 1961. The Devils Canyon Road was paved and signed as SR 263 in 1991 and the railroad became the Columbia Plateau Trail the same year.
