Primary State Highway 22-Coulee Reservoir Highway

PSH 22 (trunk)

PSH 22 started in Davenport at Jct PSH 2 and headed north, crossing PSH 3 near Kettle Falls, and continued north via Northport to the Canadian Border. PSH 22 originally crossed the Spokane River about 10 miles upstream from its mouth near Detillion. A newer PSH 22 bridge was completed closer to the mouth of the Spokane River near Fort Spokane around 1940 while Grand Coullee Dam was under construction. Since 1964, PSH 22 has been signed as SR 25. The provincial route connecting with SR 25 at the border is still numbered BC 22. PSH 22 had no PSH branches.
