Roads' ADA Transition Plan and Accessibility Services

Americans with Disabilities Act (ADA) Transition Plan

The King County Road Services Division (Roads) completed an Americans with Disabilities Act Transition Plan in April 2021. This plan will guide our efforts to make sidewalks, curb ramps and crosswalks on unincorporated King County roads more accessible to all.

The plan was developed using input from community members, an assessment of existing pedestrian facilities, and analyses of county policies, practices, and finances. The plan describes how pedestrian facilities were evaluated and prioritized, how much it will cost to improve each type of facility, and a timeline for improvements. The plan addresses all pedestrian facilities maintained by Roads, and does not include roads located inside city limits, highways, or trails.

ADA Performance Report

In December 2025, Roads published its first performance update, reporting on progress toward addressing accessibility barriers identified in the 2021 ADA Transition Plan.

The 2025 report (1mb) includes policy updates and best practices that relate to implementation. Another valuable improvement is the creation of a framework for internal monitoring of future accessibility improvements

This report is the first step to fulfilling a commitment to provide periodic updates on Roads’ progress towards plan implementation.
