US 10 and US 395 in 1969. During the 1964 highway renumbering, Washington converted its highways to the present state route system, to take effect in 1970. US 195 replaced PSH 3 and its branches along its present route, with its southern terminus at US 95 atop Lewiston Hill in Idaho and its northern terminus at I-90 in Spokane at an interchange that was opened in December 1965, along with a new segment between Thornton and Rosalia. The State Department of Highways completed construction of three highway bypasses between 1973 and 1975, avoiding Pullman, Rosalia, and Plaza, using funding originally intended for the canceled Bay Freeway project in Seattle. A four-lane bypass of Colfax was approved for construction in 1971, but deferred indefinitely due to a lack of funding. US 95 was relocated onto its present freeway, bypassing Washington state, in 1977 and US 195 was extended south into Idaho to the new interchange with a spur route traveling towards northbound US 95. The highway between Uniontown and Rosalia was designated as part of the Palouse Scenic Byway on December 19, 2002, as part of the Washington State Scenic and Recreational Highways program. In 2002, WSDOT adopted a long range plan to upgrade US 195 within the Hangman Valley in Spokane to limited-access standards by constructing new interchanges at four intersections. One of the interchanges, at Cheney–Spokane Road, was completed in 2014 at a cost of $9.4 million. Funding for the remaining interchange projects, estimated to cost $106 million in 2002 dollars, was not allocated and WSDOT is instead considering lower-cost improvements to the intersections. Increased traffic congestion on US 195 in Spokane lead to a development moratorium in place until capacity improvements are made to the highway. The first ramp meter in the Spokane area was installed at US 195's interchange with I-90 in 2019. Major junctions Spur route US 195 has a spur route near its southern terminus on the Washington–Idaho state line that travels east from US 195 to serve US 95 northbound atop Lewiston Hill. The unsigned highway, also known as the Genesee Spur, was established in 1979 on the former alignment of US 95 as it passed briefly through Washington before it was moved onto its present alignment. WSDOT included the road in its annual AADT survey in 2012 and calculated that 100 vehicles per day used the spur route. ITD designates the spur route
