"State Route 20 (SR 20), also known as the North Cascades Highway, is a state highway that traverses the U.S. state of Washington. It is the state's longest highway, traveling 436 miles (702 km) across the northern areas of Washington, from U.S. Route 101 (US 101) at Discovery Bay on the Olympic Peninsula to US 2 near the Idaho state border in Newport. The highway travels across Whidbey Island, North Cascades National Park, the Okanagan Highland, the Kettle River Range, and the Selkirk Mountains. SR 20 connects several major north\u2013south state highways, including Interstate 5 (I-5) in Burlington, US 97 through the Okanogan\u2013Omak area, SR 21 in Republic, and US 395 from Kettle Falls to Colville. SR 20's path across the Cascades follows one of the oldest state roads in Washington, established in 1896 as a wagon route. The wagon road fell into disuse within a decade, and the state government postponed the construction of a new route across the North Cascades for several decades. The development of the Skagit River Hydroelectric Project spurred boosters to lobby the state for a new route across Washington Pass, which was opened in 1972. SR 20 originally ran from the Mount Vernon area to Okanogan. By 1973, SR 20 was extended over existing state highways in northern Washington, replacing SR 113 and portions of SR 525 and SR 536 near Port Townsend; SR 30 and SR 294 from Tonasket to Tiger; and part of SR 31 from Tiger to Newport. Although US 12 has a larger east\u2013west extent, SR 20 is the longest highway in Washington at 436.13 miles (701.88 km), only 5.3 miles (8.5 km) longer than US 12. The highway has been called \"The Most Beautiful Mountain Highway in the State of Washington.\""@en . . . . . . . "Sedro-Woolley"@en . . . . . "Former SR 237"@en . "Ferry"@en . . . .
