According to allcitycodes, US 395 is a US Highway in the US state of Washington. The road forms a north-south route through the east of the state, from the Oregon border through the Tri-Cities and Spokane to the border with the Canadian province of British Columbia. The route is mainly developed between the Tri-Cities and I-90 at Ritzville with 2×2 or as a highway. The route is 443 kilometers long.

Travel directions

The Blue Bridge over the Columbia River between Kennewick and Pasco.

At Plymouth, US 395 in Oregon with Interstate 82 in Oregon double -numbered from Hermiston and Pendleton enters Washington State by crossing the Columbia River. US 395 is then double-numbered with I-82 as far as Kennewick, where it exits from I-82 and continues through town as an urban arterial. Via the Blue Bridge you cross the Columbia River again, and you arrive in the smaller town of Pasco. Here US 395 is a highway and the road crosses US 12 here. On the north side of Pasco, US 395 turns north and becomes a 2×2 divided highwayup to Ritzville, with two freeways. The road leads over the fairly flat plateau east of the Columbia River and occasionally crosses more important state routes. The distance from Pasco to I-90 at Ritzville is about 120 kilometers and one passes through a vast agricultural area. At Ritzville, US 395 merges with Interstate 90 from Seattle to begin a 100-kilometer double-numbering to Spokane.

On the west side of Spokane, US 2 from Wenatchee merges and a little further, US 195 from Lewiston ends at I-90/US 2/US 395. At the center of Spokane, the road then turns north and continues as Division Street through town. The road crosses the Spokane River here and US 2 and US 395 split in the north of the city, US 2 runs to Newport and Sandpoint in the northeast, US 395 runs northwest to the border with Canada180 kilometers away. The first kilometers after Spokane are still fairly flat, but then you enter the Selkirk Mountains, a mountain area with peaks up to 1600 meters. US 395 runs through the Colville River valley and at Kettle Falls the road crosses the Columbia River for the third time, over Franklin D. Roosevelt Lake. The road then runs along the Kettle River. To the west is the Kettle River Range, the road leads through a sparsely populated valley to the north and at Laurier follows the border with the Canadian province of British Columbia. Here Highway 395 in British Columbia continues to Castlegar.


The southern portion of the state was extended from Spokane to Oregon in the 1930s, but followed then US 410 (now US 12) and US 730, via the east bank of the Columbia. The track was not routed to Kennewick on a more direct route, over I-82, until 1985. The main highway from Pasco to Spokane was created in 1913, the road was improved in 1923 and became State Route 11. In the 1930s, US 395 was extended south from Spokane to Pasco and Oregon. In the 1950s and 1960s, the section from Ritzville to Spokane was replaced by I-90.

Pasco – Ritzville

Between Pasco and I-90 at Ritzville, US 395 has been developed as a 2×2 divided highway with varying degrees of grade separation over a distance of 120 kilometers. This isn’t a full-fledged freeway everywhere, but the US 395 is part of a higher-quality connection between the Tri-Cities and Spokane. It is the main connection in Washington State that is not an Interstate Highway.

The road was largely widened to 2×2 lanes between the 1960s and 1980s. First, the southern portion has been widened to 2×2 lanes between Pasco and Mesa, which connects to State Route 17. At this point, traffic flows north (SR-17) and northeast (US 395), so the portion from Mesa to Ritzville had lower traffic volumes than further south. In 1991, the Intermodal Surface Transportation Efficiency Act designated US 395 as a priority within the National Highway System. Subsequently, between 1991 and 1995, the northern section between Mesa and Ritzville was widened to 2×2 lanes, which was completed on November 21, 1995.

North Spokane Corridor

In the city of Spokane, part of the North Spokane Corridor has been constructed, a partly planned 17 kilometer long freeway that runs from Interstate 90 to the north of Spokane. Through north-south traffic no longer has to cross Spokane. The new highway is being built through eastern Spokane. The first 11 kilometers of this were opened in 2009 and 2012.

As early as 1956, a north-south highway through Spokane was planned, but scrapped in favor of I-90, which was being built by the federal government. Spokane had a population of 170,000 at the time and was the largest inland city in the northwestern United States. It is unclear why no Interstate Highway along Spokane for north-south traffic was planned at the time. Subsequent traffic studies in the 1960s and 1970s constantly pointed to the need for a north-south highway through Spokane, but never materialized.

The project only became concrete in the mid-1990s, with an environmental decision in 1997. Construction of the first 6 kilometers between Freya Street and US 2 started in 2001. This project was reduced in scope, it was planned to be to construct a deepened six-lane highway, eventually a 2×2 highway at ground level was realized. Construction took no less than 8 years, this segment was opened to traffic on August 22, 2009. On June 13, 2012, another 5 kilometers opened in northern Spokane.


South of Freya Street, the North Spokane Corridor should be extended to I-90. A right-of-way is not available everywhere for this, so that land and buildings have to be purchased. This is probably the most expensive part of the highway to build.

Traffic intensities

Every day, 18,000 to 48,000 vehicles pass through Kennewick, peaking at 67,000 vehicles over the Columbia River bridge. Thereafter, 18,000 vehicles run from Pasco, gradually decreasing to 9,000 vehicles per day until I-90 at Ritzville.

Thereafter, 26,000 to 28,000 vehicles pass through Spokane, dropping to 10,000 vehicles after the split with US 2. This drops to 5,000 vehicles closer to the border with Canada and eventually only 600 vehicles per day at the Canadian border.
