The Airport Way South Viaduct in neighboring Georgetown, just north of South Lucile Street, will be closed to all traffic beginning on November 28 for up to 14 months while the bridge is rehabilitated by the Seattle Department of Transportation (SDOT).
Vehicles and pedestrians will be detoured to Fourth Avenue South via South Lucile and South Industrial Way, and bicycles will be detoured all the way west to First Avenue South via South Lander Street. (Which seems like a heck of a long detour.) Denver Avenue South and South Dawson Street between Lucile and Fourth will be used as a northbound truck detour route. See a map of the detour routes here.
Crews will work from 6 a.m to 5 p.m. weekdays, as well as on some nights and weekends. Expect traffic delays in the area.
The rehabilitation project includes seismic retrofitting of the 83-year-old bridge just west of Beacon Hill and I-5. The viaduct bears 13,000 vehicles daily.
