Idaho Line to Collins House

  • Distance: 146 miles
  • Routes: SR 2, SR 195
  • Estimated Driving Time: 2.5 hours

Tour Overview

This route, known locally as the Pend Oreille-Palouse Highway, roughly parallels the Idaho-Washington Line. US 195 cuts across the southwest corner of Pend Oreille County and runs almost due south through Spokane and Whitman Counties, swinging slightly to the east near the end of the route at the Idaho Line. It continues to Lewiston, Idaho, where it forms a junction with US 410.

Idaho Line to Spokane

The northern section of the route winds through sparsely settled foothill country cut by small streams, dotted with lakes, and interspersed with prairies and shallow valleys. A hundred years ago these hills were covered with open forests of lodgepole and ponderosa pine, tamarack, and fir; the prairies were unbroken expanses of bunch grass; and the watercourses ran full and clear.
