US 395 - North Spokane Corridor - History

Originally conceived of in 1946, it has taken more than 50 years of research, planning, legislation and public input to gain approval for the North Spokane Corridor (NSC).

Other North-South arterials exist in Spokane, including Division Street, Hamilton Street and the Maple/Ash couplet, but the NSC will be the first high-speed route to connect Interstate-90 with points north of Spokane.

This new corridor will bring a greater level of safety for the traveling public and provide an efficient route for the thousands of cars and heavy trucks that pass through Spokane daily.

The corridor also includes a separate pedestrian and bicycle trail system and reserves enough room in the median for future high capacity transit throughout its length.

The new corridor will take an estimated 10-20 years to complete depending on funding, but segments of roadway and trail will be opened to the public as they are completed in sequence.

Over the past 20 years, well over 550 public meetings that included open houses, community group / neighborhood council presentations, and formal hearings have been held to gather public input and present the design and environmental aspects of this new facility. Numerous one-on-one meetings between interested citizens and WSDOT staff have been held in the WSDOT project and regional office as well.
