Where the Snake and Clearwater rivers meet, barges load grain bound nearly 750 kilometres downriver to the Pacific — Lewiston is the most inland seaport on the U.S. West Coast, and most of its heavy freight never sees a runway. Lewiston-Nez Perce County Airport (IATA: LWS, ICAO: KLWS) opens the door to Hells Canyon, the deepest river gorge in North America. Scheduled service is flown by Delta Connection (SkyWest), with daily flights to Seattle (SEA) and Salt Lake City (SLC); Seattle is the busier route. The field handles essentially no air cargo of its own; urgent shipments route through Spokane (IATA: GEG), the nearest capable cargo airport about 185 kilometres north.
