17, as the old route through Bridgeport and over the Brewster Bridge became a new branch that was later signed in 1964 as SR 173. SSH 11G was also created in 1951, traveling north from US 395 in Eltopia through Mesa and Moses Lake to Soap Lake along existing gravel roads from the late 1930s, later straightened and widened in the 1970s. SR 17 was originally a highway, extending south from Mesa to Eltopia when it was created in 1964 and codified in 1970, but was shortened by to its current route after US 395 was re-aligned between Eltopia and Connell. The new alignment, part of improvements to SR 17 in the Mesa area in the late 1960s, was approved in 1968 and opened in late 1979. No major revisions to the route of SR 17 have occurred since 1979, as WSDOT has improved the sections of the highway through widening and barriers. Within Moses Lake, the two-lane highway was designated to be widened to a four-lane limited-access highway between Pioneer Way and Stratford Road in 1997 and completed a decade later on October 8, 2007. The highway between SR 26 in Othello to US 2 west of Coulee City was designated as the Coulee Corridor Scenic Byway under the Washington State Scenic and Recreational Highways program in 1967 and under the National Scenic Byway program on September 22, 2005.
