Coeur d'Alene stretches along the north shore of Lake Coeur d'Alene, right where the Spokane River begins its run west. I-90 crosses the city east to west, linking it with Post Falls and Spokane in one direction and climbing over Fourth of July Pass toward the Silver Valley in the other. US 95 runs north through Hayden toward Sandpoint and south along the west side of the lake toward Moscow, and SH 41 connects Post Falls with Rathdrum and Spirit Lake.
In town, Northwest Boulevard brings traffic from I-90 to downtown, Sherman Avenue is the main street along the lake, and Government Way, Ramsey Road and US 95 carry most of the north-south driving. Summer is the crowded season, with visitors filling downtown lots and boat trailers lining the roads to the launches. Winter traffic is lighter but slower, and the grades on Fourth of July Pass are where plenty of cars find out their brakes or tires aren't ready.
Most airline travelers use Spokane International Airport across the state line, while the Coeur d'Alene Airport in Hayden handles general aviation. The Citylink bus connects Coeur d'Alene with Post Falls, Hayden and Plummer, but most people drive and value a repair that comes to them. Growth across Kootenai County has made the US 95 corridor through Coeur d'Alene and Hayden one of the busiest roads in North Idaho, with signals and turn lanes that test brakes every day.
