Project Description

The Seattle Department of Transportation will install new curb extensions, curb ramps compliant with Americans with Disabilities Act (ADA) standards and marked crossings where 1st Avenue W and 2nd Avenue W intersect W Harrison Street. These improvements are part of the Neighborhood Street Fund program and improve pedestrian mobility and safety.

As part of the Lake to Bay Loop, W Harrison Street helps  connect Elliot Bay to Lake Union through Uptown, Lower Queen Anne, South Lake Union and Belltown. However, the street currently lacks marked crosswalks and pedestrian amenities.

The project team selected three intersections along W Harrison Street to which curb bulbs will be added. The selected sites were chosen in conjunction with the final Bicycle Master Plan update and will complement future bicycle facilities in this area.

  • Install new curb extensions and marked crossings on W Harrison Street at 1st Avenue W and 2nd Avenue W to improve pedestrian visibility and shorten the length of pedestrian crossings
  • Construct curb ramps compliant with ADA standards at each of the new curb bulb locations
  • Repair damaged concrete panels
  • Install drainage inlets to improve the drainage system

Project Benefits

The goal of these improvements is to allow safer crossings for pedestrians and improve mobility for all users. Curb bulbs help reduce crossing lengths and improve visibility between drivers and pedestrians. The work will include:

  • Curb bulbs to facilitate safer, shorter crossings for pedestrians
  • ADA-compliant curb ramps, for smoother and better access


The work is one of the 12 projects selected by the Bridging the Gap Oversight Committee to be completed as part of the Neighborhood Street Fund program, which is funded by the Bridging the Gap (BTG) transportation levy, passed by voters in November 2006 and scheduled to end in 2015. NSF projects are identified and prioritized by communities, then sent to the Bridging the Gap Oversight Committee for final review and selection.

Project Schedule

The project reached final design in 2014. Construction will start as soon as August 3 and last approximately 6 weeks, weather dependent. The project team will continue to keep the community informed as construction details become available.
