Mercer Island is actively working to expand and improve its pedestrian and bicycle facilities, aligning with the goals set out in the Transportation Element of the Comprehensive Plan. This initiative enhances conformity with current standards and emphasizes the importance of connectivity and signage for non-motorized transport throughout the Island. The Pedestrian and Bicycle Facilities Plan, first approved in 1996 and updated in 2010, serves as a critical guide for investments and actions related to the Island's infrastructure. Current and upcoming projects include the 76th Avenue SE mid-block crossing and the East Mercer Way shoulders upgrade, which aim to provide safe and accessible routes for cyclists and pedestrians. The city encourages residents to visit the Getting Around page for comprehensive resources, including a bike route map.

This initiative demonstrates a significant commitment to improving the quality of life for Mercer Island residents through enhanced transportation options. By prioritizing these developments, the city fosters a more inclusive environment for all forms of transit, reflecting a broader trend towards sustainable urban planning.
