Signal installation at 22nd Avenue and East Union Street to begin July 20

Work will complete Phase 1 installation of Central Area Neighborhood Greenway

The Seattle Department of Transportation will begin installation of a new enhanced pedestrian push-button signal at the intersection of 22nd Avenue and East Union Street on Monday, July 20. Up to one lane will be closed intermittently in both directions of East Union Street at 22nd Avenue during normal working hours, 8 a.m. to 4 p.m., Monday through Friday. This work is being done as part of SDOT’s Central Area Neighborhood Greenway Project.

The new signal will be connected on Saturday, July 25, from 7 a.m. to 4 p.m., in order to have the least impact on traffic. Drivers will see intermittent lane closures in both directions of East Union Street with a uniformed police officer directing traffic at the intersection. Once the poles and signals have been installed and tested, crews will mark the crosswalk to guide pedestrians and bicyclists across East Union Street. Signal installation is expected to be complete by Friday, July 31, and will mark the completion of Phase 1 of the Central Area Neighborhood Greenway Project. Note that detours will also be in effect in the area on July 25 for the 23rd Avenue Corridor Improvements Project, including the northbound closure of 23rd Avenue between S Jackson and E Cherry streets and a full closure of the 23rd Avenue S and S Jackson Street intersection.

In addition to enhanced pedestrian signals, Central Area Neighborhood Greenway elements include curb ramps, bicycle pavement markings on the route, stop signs on streets crossing the greenway, and approximately one speed hump per block. Flashing beacons for pedestrians and bicycles have been installed at 25th Avenue and East Yesler Way and also at 25th Avenue and East Cherry Street. These signals are currently activated and in use.

Installation of Phase 2 and Phase 3 of the greenway (at the south and north ends, respectively) will take place concurrently beginning this fall. SDOT expects all phases of the Central Area Neighborhood Greenway Project to be complete by the end of the year, extending the route from East Roanoke Street to Rainier Avenue South on residential streets parallel to 23rd Avenue.

Neighborhood greenways are residential streets made safer and more comfortable for people of all ages and abilities to walk and ride bikes. Greenways can provide access to schools, trails, parks, transit, and neighborhood businesses.
