State Highway 8 (SH-8) is an Idaho state highway in Latah and Clearwater counties, running from the Washington state line in Moscow to Elk River. It is 53.589 miles (86.24 km) in length, and runs primarily east–west.

Route description

SH-8 begins at the Washington state line, connecting with Washington State Route 270 to Pullman. Between the cities to the north is the Pullman-Moscow Regional Airport. The two state highways comprise the "Moscow-Pullman Highway" in the 8 miles (13 km) between the two university cities.

In Moscow, Highway 8 runs east along the northern boundary of the University of Idaho campus as Pullman Road, enters an "S" curve and becomes Third Street. It briefly overlaps US 95, and runs south through the city center (one ways: Jackson St. southbound and Washington St. northbound; a block on either side of Main). South of downtown Moscow, SH-8 branches east to become the "Troy Highway" and heads out to Troy, where it intersects SH-99. East of Troy, SH-8 heads generally northeast, intersecting SH-9 shortly before entering Deary and overlapping SH-3 in Deary. From Deary, the overlapping highways run east and northeast to Bovill, where they diverge.

From Bovill, SH-8 heads south and southeast into Clearwater County. It then turns east and northeast into Elk River, where it ends at the intersection of 1st and Main Streets.

Associated trails

For non-motorized traffic, Highway 8 is paralleled to the south by a series of paved trails from the state line to Troy, on former railroad corridors. The Bill Chipman Palouse Trail originates in Pullman and terminates a mile into Idaho at Perimeter Road. There it links with the Paradise Path, which runs along the north and east edges of the UI campus and connects to the Latah Trail in southeast Moscow.
