Project Description

Click for largerThe Seattle Department of Transportation is planning to construct pedestrian improvements on 12th Avenue in the Capitol Hill neighborhood. The project will build curb bulbs at all four corners of the intersections of E Howell Street and E Olive Street on 12th Avenue. These improvements will help make important connections to nearby destinations and improve access for all users with the addition of curb ramps that align with current American Disability Act (ADA) standards.


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 expire in 2015.


The project reached final design in 2014. Construction is anticipated to start this fall and will last for 4-6 weeks. The project team will continue to keep the community informed as construction details become available.
