The project involves the reconstruction and realignment of the main roadway through the growing biotechnology hub in South Lake Union, connecting a number of urban centers to I-5 in Seattle. The project will build multi-modal improvements along Mercer and Valley Streets, including widening Mercer to create a two-way boulevard, reconstruction Valley Street as a local access street, providing new and wider sidewalks, improving connections to transit and adding bicycle lanes.
Why are we Building This Project?
The project area is in extremely poor condition and in need of rehabilitation. The roadwork will reengineer a key bottleneck and will also upgrade the water, sewer, and electrical infrastructure that serves the area. The project is fully integrated with Seattle's transit, bicycle and pedestrian plans, and it re-routes traffic flow and opens space for alternative transportation options and mixed-use development. The design criteria include innovative options for stormwater runoff, lighting and other project components. The South Lake Union development area is a pilot for Leadership in Energy and Environmental Design for Neighborhood Development (LEED-ND).
