Route description

SR 127 begins at an interchange with US 12, between Starbuck and Pomeroy, paralleling US 12 for a short period before turning northeast through some hills before passing over a small creek and leveling off. The highway turns north, passing through lightly populated rural Eastern Washington. Just after passing the Garfield–Whitman county line, the highway crosses over the Snake River and passes just east of the Central Ferry State Park. Continuing north, the highway climbs more, turning east briefly after intersecting Big Alkai Road. The highway terminates at an interchange with SR 26 in Dusty.[2]

Every year the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2009, WSDOT calculated that 560 cars use the highway at its southern terminus, and 970 use the highway at its northern terminus.[3] The entire highway is listed on both the WSDOT List of Highways of Statewide Significance,[4] which marks this portion of the highway as a critical to connecting major communities in the state, and the National Highway System, a system of roads that are important to the nation's economy, defense and mobility.[5]

History

SR 127 was part of U.S. Route 295, which was a branch of U.S. Route 95 from 1926 to 1968. US 295 started at U.S. Route 410 (now US 12) near Pomeroy. US 295 went north to the junction of SR 127 and SR 26; then, US 295 went east on SR 26 and ended at U.S. Route 195 in Colfax. While US 295 was a branch of US 95, it never connected to US 95. US 195 connected US 295 with its parent route. U.S. Route 395 also relies on US 195 for its only connection to its parent route.
