47th/Admiral Signal Project

Update: June 30, 2015

Construction Updates

Work continues at the intersection

The signal equipment arrived last week and the installation of the span wires, wiring, signal heads, push buttons and signal controller is now complete. The new signal and pedestrian heads are currently bagged and crews are connecting the signal controller wiring this week. We will begin testing the signals after Seattle City Light connects power to the signal service cabinet and SDOT signal crews install the wireless sensor systems, at the end of this week at the earliest. Testing will not affect traffic.
Crews will begin deconstructing the existing pedestrian beacon once the new traffic and pedestrian signals are brought online. During the beacon removal, traffic will be temporarily detoured around the work area.


Residents, businesses and travelers can expect the following impacts:

  • Construction activity from 7 AM – 4 PM
  • Temporary traffic detour during removal of the existing pedestrian beacon (in place approximately 10 minutes)
  • “Temporary revised signal ahead” signs alerting motorists once the new signals are running
  • Noise (very minor) and activity from construction equipment and vehicles

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.
