47th Avenue SW and SW Admiral Way Signal

Update: May 5, 2015

Construction Updates

Construction to stop for approximately three weeks

Crews are wrapping up work this week with remaining asphalt paving and laying topsoil. As we’ve mentioned, construction will stop this week until we receive equipment for the new signal. Pedestrian and bicycle access will be fully restored during this time and no lane restrictions will be in effect as part of this project. Users of the area can expect to see construction cones covering the signal pole foundations at the corners. The overhead pedestrian signal will remain in place until crews are able to install the new traffic signal. We anticipate construction will resume in approximately three weeks, at the end of May, depending on delivery of the signal equipment.
After the signal equipment is received, crews will:

  • Install signal equipment including poles and mast arms, signal heads and cabinets
  • Stripe the intersection with new crosswalks and a new left-turn pocket on SW Admiral Way
  • Remove the existing overhead pedestrian signal
  • Complete remaining landscaping


We are committed to keeping the community informed and will distribute an update approximately one week before work at the intersection resumes. When construction resumes, residents, businesses and travelers can expect the following impacts:

  • Construction activity from 7 AM – 3 PM
  • Pedestrian and bicycle detours around work areas
  • Temporary lane and parking restrictions during of-peak travel times on 47th Avenue SW, SW Admiral Way and SW Waite Street
  • Noise, dust and vibration associated with concrete removal and paving

Project Description

The Seattle Department of Transportation (SDOT) is planning a project to improve the three-way intersection of 47th Avenue SW, SW Admiral Way and SW Waite Street for people walking, biking and driving. SDOT will install a new signal and additional crosswalks at this intersection to help improve the flow of traffic.

Project Elements

The project will include

  • Installing a new traffic signal
  • Adding four additional striped crosswalks
  • Upgrading six curb ramps at key corners of the intersection to be compliant with current American Disability Act (ADA) standards
  • Replacing the existing center-turn lane with left-turn-only pockets on SW Admiral Way
  • Removing minimal parking up to 50 feet from the intersection approaches on the north and south sides of 47th Avenue SW and SW Waite Street
  • Removing the existing pedestrian signal

Project Schedule and Impacts

Project design was completed in late 2014. Construction is scheduled to begin in the spring of 2015 and will last for approximately 12 weeks, depending on weather conditions.

During construction, the following impacts can be expected:

  • Temporary parking and lane restrictions on 47th Avenue SW, SW Admiral Way and SW Waite Street
  • Pedestrian and bicycle detours around the work areas
  • Noise, dust and vibration associated with concrete removal and paving
  • Construction activity during normal work hours, from 7 AM – 6 PM

Project Outreach

SDOT is committed to engaging with the community and understanding needs in the project area. The project team will keep the community informed as the project approaches the start of construction.
