Interstate 90 West - Shoshone County

Interstate 90 west
Interstate 90 enters Idaho at Lookout Pass (elevation 4,680 feet), facing north briefly before turning west to parallel the South Fork Coeur d'Alene River. A truck brake check area lies along the eastbound lanes beyond the Exit 0 on-ramp from Montana. Photo taken 09/01/06.
Interstate 90 hugs the hillside of Runt Mountain on its westerly curve toward Mullan. The welcome sign for Idaho coincides with a sign advising motorists of Pacific Standard Time Zone. Photo taken 09/01/06.
Within Idaho, Interstate 90 is designated the Caption John Mullan Highway. Mullan directed a crew of 230 soldiers and civilians that built the Mullan Road, a military and supply route, from Fort Walla Walla to Fort Benton between spring 1859 and August 1, 1860.1 I-90 today parallels much of the original course of the Mullan Road. Photo taken 09/01/06.
Winding westward, south of Snowstorm Peak, Interstate 90 straddles the hillside north of the South Fork Coeur d'Alene on the five-mile trek to Mullan. Wallace and Coeur d'Alene lie ahead over the next 59 miles. Photos taken 09/01/06.
A westbound wayside follows, allowing drivers a place to stop and read about the Murray Gold Fields and the 1910 Fire. The 1910 fire consumed more than 3,000,000 acres of timberland during the drought-ridden summer of 1910. Murray began as a permanent camp established on January 22, 1884 for the many gold miners that flocked to the area. The settlement was the Shoshone County seat between 1885 and 1898. Photos taken 09/01/06.
Six more ess curves await westbound motorists from the historic site pull-off to the first Idaho exit at Mullan. Photo taken 09/01/06.
The last ess curve includes a runaway truck ramp situated just east of the Willow Creek Road overpass. Interstate 90 lowers over 1,300 feet in elevation from Lookout Pass to the city of Mullan. Photos taken 09/01/06.

Willow Creek Road originates from within Coeur d'Alene National Forest as National Forest Road 8008 to the south of Interstate 90. The local road parallels I-90 westward to become Friday Avenue, following a stretch of old U.S. 10 from this overpass into Mullan. Photo taken 09/01/06.
Interstate 90 west reaches Exit 69 in one mile, where Business Loop I-90 begins a 1.00-mile trek through Mullan. Photo taken 09/01/06.
A second truck escape ramp lines the westbound lanes of Interstate 90 leading toward the diamond interchange with Atlas Road and Business Loop I-90 west. Photo taken 09/01/06.
Exit 69 departs Interstate 90 west for Atlas Road north and Business Loop I-90 west to River Street and the city center. Photo taken 09/01/06.
