US 395 – NSC I-90 Connection

Project overview

This is the final four projects to construct the North Spokane Corridor and connect to I-90. This is the last step to create the limited access 10.5 mile freeway north/south through Spokane that will remove freight and trips off of the local system.

What to expect

The construction of the North Spokane Corridor connection to I-90 will be broken into four projects, with the first anticipated to begin in either late 2025 or spring of 2026. Completion is expected in 2030 as the final link and connection for the North Spokane Corridor.

The four projects are anticipated to be broken into four different stages:

• Stage 1 - Hamilton Street to Thor Street local connections and ramp structures, with construction starting in the spring of 2026.
• Stage 2 - NSC/I-90 interchange structures with construction starting in late summer 2026.
• Stage 3 - Freya Street to Sprague Avenue interchange, local street connections and ramp structures with construction starting in either late 2026 or spring 2027.
• Stage 4 - NSC/I-90 interchange structures with construction starting in spring 2027.

The traveling public can expect closures to various locations on both city streets and I-90 throughout the duration of all four project stages. Closures and detours will be signed and communicated via electronic reader boards, press releases, travel advisories and social media.
