Current Emphasis
Extend the corridor to I-90 and
provide a connection to the
Interstate. This practical design allows
use of the full length of the corridor
and can be opened in sections as
construction progresses south.

Cost to Complete
Cost to complete the North Spokane Corridor to I-90 is $750 million, $879 inflated to year of construction.  The bulk of construction was funded by the Legislature to occur from 2019 to 2027.

Why is WSDOT building the North Spokane Corridor?
This project improves mobility by allowing motorists and freight to move north and south through metropolitan Spokane, from I-90 to US 395 at Wandermere. Once complete, the NSC will decrease travel time, fuel usage, and congestion, while  improving safety by reducing collisions on local arterials.

The NSC is considered a multi-modal corridor; as a freeway, it maximizes vehicle capacity and contributes to freight hauling competitiveness, by moving vehicles and freight traffic away from local arterials and on to a free flowing freeway. It supports alternative transportation choices by providing: park and ride lots, vanpooling operations, reserves enough right-of-way for high capacity transit and provides a pedestrian/bicycle trail along its full length.

The End Result
When fully complete, the North Spokane Corridor will be a 60-mile per hour, 10.5 mile-long north/south limited access facility; that connects to I-90 on the south end (just west of the existing Thor/Freya Interchange) and connects to existing US 2 (at Farwell Road) and US 395 (at Wandermere) on the north end.
Interchanges are located along the corridor, at: Trent Avenue (SR 290), Wellesley Avenue, Francis/Freya Street, Parksmith Drive, US 2, and US 395 at Wandermere.

Project Benefits
Consider the following benefits:

  • Travel time between Wandermere and I-90 will be shortened to approximately 12 minutes.
  • The NSC is a free flowing freeway facility that doesn’t conflict with schools, parks or shopping areas; but still will have reasonable access to them.
  • Fewer trucks will be on the local arterials, because they will be using the freeway for north and south destinations points.
  • Spokane will have cleaner air, because drivers won’t be stopping and idling at intersections.
  • Provides a safe bicycle/pedestrian trail that connects to the Centennial Trail and other established trail systems, as well as neighborhoods within the Spokane area.
  • The NSC creates jobs that will improve the economic vitality of the region.

What is the project timeline?

  • In April 1997, the NSC Final Environmental Impact Statement (FEIS) was approved by the Federal Highway Administration (FHWA). In September 2000, a supplemental FEIS was approved for the Spokane River north to US 395 at Wandermere section.
  • In August of 2001, the North Spokane Corridor broke ground with the first construction project titled “Hawthorne Road to US 2 - Grading”. This was a grading and drainage project that was completed in July 2002.
  • In February 2003, a Design and Access Hearing was held for the I-90 to the Spokane River section. In May 2005, an EIS re-evaluation was approved by the FHWA, for this section. The “Findings and Order” was adopted in July 2005, and the final limited access was established in October 2005.
  • In 2003, the State Nickel Gas Tax Package allocated $321 million to fund the project between 2003 and 2011; this allocation provided funds for design, right-of-way purchases and construction of the Francis to Farwell and the US 2 Wandermere & US 2 Lowering projects.
  • In 2005, the State 9.5 cent, Transportation Partnership Act (TPA) gas tax allocated $152 million to fund the project between 2007 and 2019. This allocation provides funds for right-of-way acquisitions north and south along I-90, between the Liberty Park Interchange and the Sprague Avenue Interchange, for the future Collector/Distributor System and to design and construct a noise wall project along this same section of I-90. This allocation also provided funding to design the “shovel ready”, southbound lanes project between the Francis/Freya and Farwell Interchanges.
  • In 2009, the Washington State Legislature allocated an additional $28 million in TPA funds for the corridor. WSDOT chose to use this funding in the Hillyard area, from the Spokane River to the Francis/Freya Interchange. This additional $28 million allocation brings the total TPA funding for the corridor to $180 million ($152 million in 2005, plus $28 million in 2009).
  • On August 22, 2009, the first Nickel Project, Francis to Farwell (between the Francis/Freya and Farwell Interchanges) opened to traffic. 
  • The 5 1/2 mile north half of the NSC is fully completed and open to traffic in October 2012.
  • The first project for the south half, the Francis Avenue Bridge Replacement project began construction in late 2012 and was fully opened to traffic in June 2014.
  • The second southern half project, BNSF Realignment began in late 2013 and was completed in late 2015.
  • The Connecting Washington package, passed by the Legislature in 2015, provides full funding to complete the North Spokane Corridor.

How long will it take to build the NSC?

The final series of construction projects will begin in late 2017 and continue until the entire facility is completed in 2029.  The construction funding schedule was provided by the Legislature as part of the Connecting Washington package.
