NE 45th St Viaduct to Close Jun 14 – Sept 10

The NE 45th Street Viaduct’s existing west approach is nearing the end of its structural life and needs to be replaced to maintain a safe and efficient travel corridor for vehicles, pedestrians and bicycles. SDOT will replace the 468-foot west approach during the University of Washington’s summer session when traffic volumes are lighter. Between June 14 and September 10, the viaduct will be completely closed to all traffic, pedestrians and bicycles.

The NE 45th Street viaduct is a major thoroughfare in northeast Seattle. It connects I-5 and the University District to the Northeast Seattle neighborhoods, the University Village, the University of Washington’s Husky Stadium, Seattle Children’s Hospital, and businesses along Sand Point Way NE.

SDOT recently awarded the construction contract to Guy F. Atkinson Construction, LLC, the lowest bidder. The engineering construction estimate for the project was approximately $7.5 million; Atkinson’s estimate came in at just over $4.5 million. The cost savings will allow SDOT to put money back into the Bridging the Gap program for future projects.

The contractor has begun site preparation activities near the NE 45th Street Viaduct. During the closure period this summer, traffic will be detoured to nearby major arterial streets including 25th NE and NE 65th Street to the north, and Montlake Boulevard NE and NE Pacific Street to the south. Please see the project Web site at for specifics on detour routes and options to bike, bus and walk around the area.

SDOT will host an open house on June 9 from 4 to 7 p.m. at the University Heights Community Center (5031 University Way NE) to talk with neighbors about construction impacts and prepare the traveling public for the closure and detour.

To encourage busing, biking and walking during the closure, SDOT is providing incentives and information on local bus, bike and walking routes in the area. SDOT will also provide free bicycle lectures and workshop to promote biking on the Burke Gilman Trail, which will remain open during construction.

SDOT will also continue to work closely with local government, institutions, community groups, businesses, residents, as well as transportation agencies and other nearby construction projects through the completion of construction on this project.
