Lake Washington Boulevard Renovations

Summer 2025

Lake Washington Boulevard is a valued space and vital connection for communities in Southeast Seattle and beyond. Your input played a key role in shaping the design of the safety and access improvements in this project. Learn more here: Outreach Summary for the Lake Washington Boulevard Renovations Project. 

Next Steps

The City of Seattle is implementing this project through a phased approach to effectively manage resources, expedite improvements, and address community needs in a timely and comprehensive manner. This strategy allows the City to deliver immediate, high-priority safety and accessibility upgrades while planning for long-term enhancements across the entire three-mile corridor within the available budget. The phased approach also enables the City to leverage matching funds from the Washington State Transportation Improvement Board’s Complete Streets grant and supports an incremental, adaptive process that prioritizes continuous monitoring and data-driven adjustments to ensure the project’s success.
