ADA Curb Ramps Upgrade Project
Work began in early June 2025
A newly upgraded curb ramp at the corner of 15th Ave SW and SW 98th St in White Center.
Status update
August 20, 2025
Along the new RapidRide H Line, 27 outdated sidewalk curb ramps at 10 intersections were replaced with ADA compliant ramps. Crews will return to the project site to complete some final punch list items through late summer.
Overview
King County Road Services replaced 27 outdated sidewalk curb ramps at 10 intersections, and added two new crosswalks, along Metro’s new RapidRide H –Line route in White Center. Many of the original curb ramps along this bus corridor were over 30 years old and needed to be brought to modern standards. The improvements make it easier and safer for people walking or in wheelchairs to use the sidewalk when walking to or from a RapidRide bus stop.
The RapidRide H Line operates between the Burien Transit Center and Downtown Seattle. Cities of Burien and Seattle recently improved curb ramps located along their sections of this corridor and now unincorporated King County has updated our section of the route to improve safety and mobility for all.
Curb ramps benefit the whole community and are used by pedestrians, those using strollers, the elderly, in addition to people who are physically disabled.

Benefits of modern sidewalk curb ramps
Curb ramps in 10 intersections were removed and replaced with modern ramps during this project. When public spaces are improved and made more accessible, the whole community benefits. Curb ramps make it easier for people who are disabled. Ramps also make it easier for people pushing strollers, those who need to use a handcart, or people carrying heavy bags.
Our new curb ramps have detectable warning surfaces so that sight-impaired pedestrians know where to safely exit the sidewalk.

The bright color and raised bumps also help disabled people find the other side of the street more easily. View larger image (534KB)
