47th Avenue SW and SW Admiral Way Signal

Update: April 20, 2015

Construction Updates

Construction continues on the south side of 47th Avenue SW and SW Admiral Way

This week, crews will continue electrical and utility work on the southeast and southwest corners at 47th Avenue SW and SW Admiral Way. We anticipate pouring new curbs and sidewalk beginning this Friday, April 24, continuing into next week.

Corners may be closed to pedestrians and bicyclists during work. People walking and biking will need to follow marked detours or find an alternate route. Access to Alki Mail & Dispatch will be maintained at all times.

Installing the new signal

We are approaching a pause in construction while we wait for the delivery of signal equipment. We anticipate completing work at the corners in the beginning of May and will stop work in the area until this equipment is delivered. Once the materials arrive, work will resume and continue for approximately three more weeks while we install the signal. We will continue to keep you informed as more information is available related to installation and configuration of the new signal.

Construction timeline

Construction will take approximately four months to complete, weather depending. Crews will first begin working at each corner demolishing the existing curbs and preparing 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 delivery/installation of the signal. The existing overhead pedestrian signal will remain in place until the new signal is operation and crosswalks are marked.

What to expect during construction

  • 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.
