The highway starts in rural Wasco County in Central Oregon at an intersection with US 97. US 197 travels north as a continuation of The Dalles-California Highway No. 4 through the cities of Maupin, Tygh Valley, and Dufur to The Dalles. Within The Dalles, the highway becomes concurrent with US 30 and intersects Interstate 84 (I-84) before it crosses over the Columbia River on the The Dalles Bridge into Washington. The highway continues through the neighboring city of Dallesport in Klickitat County and terminates at a junction with State Route 14 (SR 14).

Route description

US 197 runs 69.93 miles (112.54 km) in Oregon and Washington and is maintained by the Oregon Department of Transportation (ODOT) and Washington State Department of Transportation (WSDOT).[1][2]

Oregon

US 197 crossing the Deschutes River into Maupin in rural Wasco County

US 197 begins at an intersection with US 97 at Shaniko Junction in unincorporated Wasco County, located between the cities of Madras and Shaniko in Central Oregon.[3] The highway, a continuation of The Dalles-California Highway No. 4,[4] travels northwest over the 3,363-foot-high (1,025 m) Criterion Summit and down along Stag Canyon through the community of Criterion towards Maupin.[5][6] US 197 crosses the Deschutes River and a BNSF rail line on a warren truss bridge,[7][8] becoming Deschutes Avenue as it passes South Wasco County High School and through the city of Maupin.[9][10] The highway continues west into the Juniper Flat and intersects Oregon Route 216 (OR 216), designated as Wapinitia Highway No. 44,[4] and forms a concurrency.[11] US 197 and OR 216 travel north and northwest to Tygh Valley,[12] where OR 216 leaves the concurrency and heads east on Sherars Bridge Highway No. 290 towards Grass Valley.[4][13][14] The lone highway continues north up Butler Canyon onto Tygh Ridge,[15][16] passing through the 2,710-foot-high (830 m) Tygh Grade Summit.[17] US 197 travels east of Dufur and down into the Columbia River Gorge, entering the city of The Dalles.[18][19][20] The highway begins a 0.24-mile-long (0.39 km) concurrency with US 30, traveling north over a east–west BNSF rail line to a diamond interchange with I-84.[8] US 197 leaves the interchange and the state of Oregon on The Dalles Bridge, crossing over the Columbia River into Washington.[21][22][23]

Washington

US 197 is carried by The Dalles Bridge over the Columbia River into Washington

US 197 enters Washington on The Dalles Bridge, a steel cantilever truss bridge that crosses the Columbia River downstream of The Dalles Dam,[24][25] and travels into Dallesport in Klickitat County.[26] The 2.76-mile-long (4.44 km) highway continues north past Columbia Gorge Regional Airport to its northern terminus, an intersection with SR 14.[2][23][27] US 197 is defined by the Washington State Legislature as SR 197, part of the Revised Code of Washington as §47.17.382.[28] Every year, WSDOT conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of AADT, which is a measure of traffic volume for any average day of the year. In 2011, WSDOT that Washington section of US 197 served between 3,600 to 5,800 vehicles, mostly on The Dalles Bridge.[29]

History

When US 197 was created in the 1950s, US 197 went from US 97, its current southern terminus, north to U.S. Route 830 and east to US 97 in Maryhill, Washington. The portion from US 830 to US 97 was co-signed with US 830 until 1968, when US 830 was removed from the system and US 197's northern terminus was moved to SR 14, which is the former route of US 830. Even though the section was removed in 1968, the portion of US 197 was not removed from most highway mileage logs until 2006.
