The Seattle Department of Transportation (SDOT) will begin work to rehabilitate the Airport Way South Viaduct on November 28.  The rehabilitation of this 83-year-old Georgetown Neighborhood bridge just north of South Lucile Street requires that it be closed to all traffic for up to 14 months.

Vehicles and pedestrians will be detoured to Fourth Avenue South, while bicycles will be detoured to First Avenue South. Additional detour information is as follows:

• Southbound traffic will be detoured at South Industrial Way to Fourth Avenue South, returning to Airport Way South via South Lucile Street.
• Northbound traffic will be detoured at South Lucile Street to Fourth Avenue South returning to Airport Way South via South Industrial Way.
• Denver Avenue South and South Dawson Street between South Lucile Street and Fourth Avenue South will primarily be used as a northbound truck detour route.

There is a map of the detour route on SDOT’s project Web site.

SDOT’s contractor for this project will have crews working from 6 a.m. to 5 p.m. on weekdays, and on occasional nights and weekends. Drivers should expect traffic delays on Airport Way South near the viaduct and allow extra time for their trips. There will be some parking restrictions adjacent to the viaduct and its approaches.  For information on changes to bus service, look for Rider Alert notices at bus stops, visit Metro Online at www.kingcounty.gov/metro, or call (206) 553-3000.

With over 13,000 vehicles traveling on Airport Way South daily, stress to the structure is significant. Completing this project is necessary to maintain a safe and reliable transportation corridor. The project work includes seismic retrofitting as well as rehabilitation of the mainspan. The estimated total project cost of this Bridging the Gap project is $34 million.
