North Spokane Corridor: Spokane River to Columbia

Spokane, WA: Extension of the North Spokane Corridor from Wellesley Ave to Euclid Ave

Project Details

The River to Columbia Project marks Kuney's fifth project on the NSC, which will ultimately provided a much needed north-south freeway in Spokane, connecting I-90 with US 395.

This one mile long project will complete the Wellesley Ave Interchange, including the mainline NSC bridge over Wellesley and two ramp bridges over BNSF spur line tracks. The project will also complete the roadway excavation and embankment required to complete the mainline NSC down to the north side of Carlisle Ave, which includes a mainline bridge over Euclid Ave., retaining walls, HMA and concrete paving, drainage, and ITS and illumination appurtenances for future use.

In total, Kuney and its partners will construct four new bridges, and over 5,500 LF of cantilevered retaining walls, two roundabouts, and place over 2.5 miles of concrete pavement. Once complete, the NSC will be extended from its current end location at Freya Ave, to the new Wellesley Ave interchange.
