U.S. Route 195 (US 195) is a north–south

United States Highway, of which all but 0.65 miles of its 94.02 miles (1.05 of 151.95 km) are within the state of Washington. The highway starts in rural Idaho north of the city of Lewiston as a state highway in an interchange with US 95. As the road crosses into Washington it becomes a state highway that connects communities in the Palouse region of Eastern Washington. US 195 travels north, serving the cities of Pullman, Colfax and Rosalia in Whitman County before continuing into Spokane County to its terminus in the city of Spokane at an interchange with Interstate 90
(I-90).

The first section of US 195 designated as part of Washington's state highway system was codified in 1913 from Colfax to Spokane as the

State Road 3 in 1923 and US 195 during the creation of the US Highway System on November 11, 1926. Originally, the northern terminus of the highway was at US 95 in Sandpoint, but was truncated to Spokane after US 2 was extended west from Bonners Ferry
in 1946.

US 195 was cosigned with

divided highway
.

Route description

US 195 runs 94.02 miles (151.31 km) in Idaho and Washington and is listed in its entirety as part of the National Highway System,[4][5] a system of roads crucial to the nation's economy, defense and mobility.[6] As a state highway in both states, the roadway is maintained by the Idaho Transportation Department (ITD) and Washington State Department of Transportation (WSDOT).[1]

Idaho

US 195 travels within Idaho for 0.577 miles (0.929 km) from an interchange with US 95 to the Washington state line, entirely north of Lewiston atop the Lewiston Hill in unincorporated Nez Perce County.[7] ITD surveys the roads under its control on a regular basis to measure the amount of traffic using the state's highways. These traffic counts are expressed in terms of annual average daily traffic (AADT), a calculation of the average daily number of vehicles on a segment of roadway. A July 2011 survey reported average daily traffic of 6,761 vehicles being served the US 95 interchange.[8]

Administratively, US 195 does not exist in Idaho. According to ITD's milepoint log, both carriageways are officially US 95 ramps into Washington state.[2]

Washington

Hangman Creek in Spokane
, viewed from the east

US 195 travels 93.37 miles (150.26 km) north through the

Hangman Creek and ends at a partial cloverleaf interchange with I-90, cosigned with US 2 and US 395.[7][17]

US 195 is defined by the Washington State Legislature as SR 195.[18] 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 2012, WSDOT calculated that the busiest section of US 195 within Washington was in Hangman Valley before the I-90 interchange in Spokane, serving 19,000 vehicles, while the least busiest section was between Pullman and Colfax, serving 3,100 vehicles.[19] The entire route of US 195 is designated as a Highway of Statewide Significance by WSDOT,[20] which includes highways that connect major communities in the state of Washington.[21]

History

The

PSH 3 in 1937, while State Road 6 became PSH 6.[34][35]

Shields of US 195, circa 1961, and former PSH 3

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,[18][40] 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 7.2-mile (11.6 km) segment between Thornton and Rosalia.[41][42]

Between 1973 and 1975,

State Department of Highways completed construction of three highway bypasses around Pullman, Rosalia, and Plaza.[43][44][45] Funds that were originally intended for the canceled Bay Freeway project in Seattle were instead redirected to the bypasses earlier in the decade.[46][47] A four-lane bypass of Colfax was approved for construction in 1971, but deferred indefinitely due to a lack of funding.[48][49] The western bypass of Pullman was completed in 1974 at a cost of $1.04 million.[43]

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

limited-access standards by constructing new interchanges at four intersections.[53] One of the interchanges, at Cheney–Spokane Road, was completed in 2014 at a cost of $9.4 million.[54] 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.[53][55] Increased traffic congestion on US 195 in Spokane lead to a development moratorium in place until capacity improvements are made to the highway.[56] The first ramp meter in the Spokane area was installed at US 195's interchange with I-90 in 2019.[57]
