Spokane Airport Interchange Construction Update

Another adjustment to the schedule for work on US 2 near Spokane International Airport (SIA). The revised plan for the remaining series of on and off ramp closures to grind out old pavement and place new asphalt is below. The full closures are limited to single-lane ramp sections. The most intense work will be scheduled during overnight hours.

During the following days and hours, single-lane segments of on and off ramps leading to and from SIA on US 2 and Sunset Hwy. will be closed for construction. Detours will be in place but expect delays and allow extra time to avoid missing flight connections.
