the Hagadone Corporation. Infrastructure Transportation Roads and highways In Coeur d'Alene, the city roads are oriented in the four cardinal directions, with roads going north–south being designated as "streets" and roads going east–west as "avenues". Sherman Avenue divides the streets into north and south and Government Way divides the avenues into east and west. Major east-west thoroughfares include Sherman Avenue and Harrison Avenue and major north–south thoroughfares include U.S. Route 95, Government Way, 15th Street, and Ramsey Street. Coeur d'Alene is accessed from Interstate 90 at Exits 11 through 15. Not too far to the east on I-90 is the Fourth of July Pass and further east near the Montana border is Lookout Pass that traverse the Rocky Mountains near Mullan, Idaho. The route of the interstate east of Coeur d'Alene closely mirrors that of the old Mullan Road, although I-90 crosses the Fourth of July Pass south of John Mullan's passage, which was carved out using pickaxes and shovels on July 4, 1861, and is now listed on the National Register of Historic Places and marked by a monument. Before the construction of I-90, the city was served by U.S. Route 10, which ran through downtown; this route is now Northwest Boulevard and Sherman Avenue. The former U.S. 10, between I-90 exits 11 and 15, is now designated as Interstate 90 Business. Interstate 90 was completed on October 14, 1960, and dedicated by Governor Robert E. Smylie 10 days later as the state's first major interstate highway project to be completed. Major state highways in the area include Idaho State Highway 41 and U.S. 95. Idaho State Highway 41 has its southern terminus in Post Falls and is routed from I-90 northward to the Newport, Washington area, where it is in the vicinity of U.S. Route 2 and Washington State Route 20 and U.S. 95 runs north to south across the whole of western Idaho, connecting the city with Sandpoint to the north and Moscow, Lewiston, and eventually Boise to the south. Originally an exclusively in-state highway when it was proposed by the United States Numbered Highway System in 1925, spanning from the Canadian border to Payette, it is significant for connecting the long-disconnected northern panhandle to the rest of the state; prior to the construction of U.S. 95, one would have to travel through Washington and Oregon for passage to avoid the mountainous topography.
