Lewiston | USA Idaho

Lewiston is the seat of Nez Perce County and serves as the primary port and industrial center for Northern Idaho. It is located at the confluence of the Snake and Clearwater Rivers, directly across from Clarkston, Washington.

Historical Timeline

The area is part of the ancestral homeland of the Nez Perce (Nimiipuu) people. In 1805, the Lewis and Clark Expedition passed through the confluence. The city was founded in 1861 during the Clearwater Gold Rush and served as the first capital of the Idaho Territory from 1863 to 1864. Its economic history is defined by its status as an inland seaport and a center for timber and paper production, specifically the PotlatchDeltic (formerly Potlatch Corp) mill established in 1927.

The city is the western terminus of US-12 and a major stop on US-95. Lewiston-Nez Perce County Regional Airport (LWS) provides commercial flights to Salt Lake City and Denver. The city is unique for its "water highway," with tugs and barges transporting grain and wood products to the Pacific.

Facts & Legends

Lewiston is the farthest inland port on the West Coast, reachable by ocean-going barges via eight locks on the Columbia and Snake Rivers. A local legend involves the "Ghost of the Spiral Highway," a phantom hitchhiker reportedly seen on the old winding road. Historically, the city is unique for the "Capital Theft" of 1864, where the territorial seal and records were allegedly smuggled out of Lewiston by night to move the capital to Boise.
