New signal and crosswalks coming to 47th Ave SW and SW Admiral Way

The Seattle Department of Transportation will begin work to install a new traffic signal, new crosswalks and upgraded curb ramps at the five-leg intersection of 47th Avenue SW and SW Admiral Way at SW Waite Street. Crews will work at this location for up to four months.

Residents, businesses and travelers can expect to see crews and equipment in the area beginning tomorrow, March 10. Construction will begin with survey work and site preparation. Crews will begin saw cutting at the northeast corner of 47th Avenue SW and SW Admiral Way as soon as Wednesday, March 11, with demolition of the northeast corner to follow on Thursday, March 12. “No park” signs will be placed around the work zones prior to the start of work. We will notify adjacent properties prior to the start of work at a given corner.

Crews will begin work to demolish the existing curbs and prepare to set the foundation for new signal equipment. Crews will continue to work in preparation for installation of the signal but there may be a lull of activity between the corner work and installation of the new signal. The existing overhead pedestrian signal will remain in place until the new signal is operational and the crosswalks are marked. No impacts are expected to adjacent Metro bus stops.

During construction you can expect:

  • Construction activity from 7 a.m. – 4 p.m., Monday to Friday
  • Pedestrian and bicycle detours around work areas
  • Temporary lane and parking restrictions during off-peak travel times on 47th Avenue SW, SW Admiral Way and SW Waite Street
  • Noise, dust and vibration associated with concrete removal and paving

If you have questions or concerns during construction, contact Rachel McCaffrey, construction outreach lead, at rachel.mccaffrey@seattle.gov or 206-615-0925.
