US-12 and US-95: the primary regional connectors

US-12 runs east-west through Lewiston along the Clearwater River corridor, connecting toward the Idaho Panhandle and Montana, while US-95 runs north-south, connecting to Coeur d'Alene and North Idaho -- the primary commuting and travel corridors for residents.

The Port of Lewiston: a real, distinct river-shipping transportation mode

Idaho's only seaport provides a real, distinct multimodal transportation option -- river barge transport combined with rail and trucking -- unlike any other market in this project's Idaho build, though this mode primarily serves freight and commercial shipping rather than personal travel.

A genuinely car-dependent city for daily transportation

Lewiston carries no significant citywide public transit system for daily personal transportation -- residents rely on driving, consistent with most smaller Idaho markets in this dataset.
