 The current interchange between US 2 and the North Spokane Corridor, a spur route of US 395, was opened in November 2011 to coincide with the opening of the northernmost of the future freeway.In the early 2000s, WSDOT began planning a series of 56 projects to improve the US 2 corridor between Snohomish and Skykomish, where the highway is two lanes wide and has been the site of over 2,600 collisions between 1999 and 2007 that caused 47 fatalities.A study, conducted by WSDOT in 2007, divided the corridor into four segments, each with a specialized development plan.
