South Ballard Corridor Safety Improvements Project

Construction on Shilshole Avenue NW

SDOT will begin repairing the south shoulder of Shilshole Avenue NW between NW 46th Street and 24th Avenue NW in the spring of 2015. Questions? Read more about the construction impacts and timeline below, view a project fact sheet or contact the team for more information.

Project Overview

The South Ballard Safety Improvements Project aims to improve safety and reduce conflict zones between people walking, biking and driving. Some of the elements of this project include shoulder repair, intersection improvements, changing travel lanes and installing signage.

Project elements include:

  • A two-way bike lane on NW 45th Street between 11th Avenue NW (at the Ballard Fred Meyer) and NW 46th Street (just to the west of the Ballard Bridge)
  • Modified travel lanes on NW 45th Street between 11th Avenue NW and NW 46th Street to become one-way eastbound for motorists
  • New intersection signage and painted curb extensions on Ballard Avenue NW at NW 48th street and on Ballard Avenue NW at 17th Avenue NW
  • New 5-foot concrete shoulder on the south side of Shilshole Avenue NW
  • Crosswalk on NW 46th Street at Shilshole Avenue NW
  • Bike ramp at the southeast corner of 24th Avenue NW and NW Market Street


Project schedule

This project began in late 2013 with changes to NW 45th Street and will continue in the spring of 2015 with the shoulder repair on Shilshole Avenue NW. SDOT has made adjustments to the roadway based on community feedback which included

  • Clarifying the western entrance into the two-way bike lane at the intersection of NW 45th Street and 11th Avenue NW
  • Widening the two-way bike lane as it crosses rail tracks under the Ballard Bridge

In the spring of 2015, SDOT will begin repairing the south shoulder of Shilshole Avenue NW between NW 46th Street and 24th Avenue NW and install a bike ramp at the southeast corner of the intersection of NW Market Street and 24th Avenue NW.

We expect the work will begin in the spring of 2015 and last for about 4-6 weeks. During construction, you can expect:

  • Lane restrictions on Shilshole Avenue NW between 10 AM and 4 PM
  • Noise, dust and vibration associated with concrete removal and paving
  • Temporary driveway, walkway and parking restrictions
  • Pedestrian and bicycle detours around the work area

Construction activity during normal work hours between, 7 AM and 6 PM


SDOT is committed to working with property owners and tenants along the corridor prior to and throughout construction to keep you informed and address concerns. The project team will reach out to businesses along the corridor in January and February to share construction impacts associated with work along Shilshole Avenue NW.
