Travel directions

US 95 near Cambridge.

US 95 at Lewiston.

In an uninhabited desert, US 95 in Oregon enters the state of Idaho from Winnemucca, Nevada, and then heads north. One then descends to the valley of the Snake River. You pass through Homedale, after which the road around Parma is double numbered with US 20 / US 26. The roads then turn toward Oregon, where US 95 crosses Interstate 84 and US 30. You pass through Fruitland and then through Payette, two regional towns. Then one leaves the valley of the Snake River and the road follows a route north, some distance from the Oregon border.. The area that US 95 runs through consists of a dry desert mountain range that turns into a forested area to the north. You then pass through the Payette National Forest. The road runs west of the Salmon River Mountains and begins a long route north. The road then follows the valley of the Salmon River. A little further west, the Snake River passes through Hells Canyon. The distances are great and you don’t get through many more places bigger than a village. A slightly larger town is Grangeville. Here you come to a plateau, after which the road branches off to the northwest, towards Lewiston. The city is reached from the east, via a short double numbering with the US 12. One then enters the valley of the Clearwater River, a tributary of the Snake River. One then ascends again to the plateau, after which the connection with the US 195 follows on the border with the state of Washington, the road to Spokane, which actually runs parallel to the US 95. The area through which you then pass is a lot greener with meadows and mountains in the distance.

You then pass through the town of Moscow, after which the road starts on a route to the north. You pass through an area with somewhat lower mountains and not too much forest. The road then runs along Lake Coeur d’Alene. One then passes through the town of the same name, which has a small agglomeration. Interstate 90 is crossed here. The road then continues along Lake Pend Oreille, where US 2 merges from Spokane and begins a 40-mile double-numbering road north. To the west is a slightly higher mountain range and at Bonners Ferry US 2 turns back to Kalispell in Montana. Not far after that, the border with Canada follows at Eastport. British Columbia ‘s Highway 95then continue towards Cranbrook.


US 95 was created in 1926 and originally ran only from Fruitland to the border with Canada in central and northern Idaho. In 1938 the route was extended a long way south to Blythe in California.

Traffic intensities

Every day, 1,500 vehicles drive between the Oregon border and Marsing and 2,100 vehicles at Homedale. 6,600 vehicles and 19,000 vehicles drove through Parma between Fruitland and Payette. Further north, this drops to 1,700 to 2,300 vehicles between Weiser and New Meadows. Between New Meadows and Grangeville, 1,700 to 2,000 vehicles and 3,000 to 3,900 vehicles continue to Lewiston. Between Lewiston and Moscow, 5,000 vehicles and 2,400 to 2,900 vehicles ran between Moscow and Coeur d’Alene. North of I-90, 28,000 vehicles drove, then rapidly descending to 12,000 vehicles at Sandpoint and 6,100 vehicles as far as Bonners Ferry. 1,000 vehicles drove on to the border with Canada.

Mountain Passes in Idaho

Galena Summit in central Idaho.

This is an overview of mountain passes in Idaho above 2,000 feet.


According to Liuxers, Idaho’s high mountain passes are primarily in the Bitterroot Range on the border with Montana, and are scattered throughout the center and eastern part of the state. The highest mountain pass, Galena Summit is also the most beautiful in Idaho at 2,652 meters. The road network in central Idaho is thin and erratic and mostly follows the valleys, so there have traditionally been few through connections in this area. There are relatively more through mountain routes through the Bitterroot Range. Idaho’s mountain passes are all below the tree line, but most in the south of the Bitterroot Range are in open steppe territory. The passes in central Idaho are usually more spectacular than those in the Bitterroot Range because the highest parts of this mountain range are not criss-crossed by mountain passes.


Not much is known about the history of the mountain passes in Idaho. The Lost Trail Pass is believed to have been used by the Lewis and Clark Expedition of 1804-1805 that first mapped the northwestern United States from the east. They crossed northern Idaho. Galena Summit was also discovered relatively early, in 1824.
