Magnolia Bridge Planning Study

What's happening now?

We've been collaborating with local stakeholders to develop an Emergency Transportation Response Plan for the Magnolia Community in the event one or more of the bridges are closed. The plan provides actions and processes to ensure resiliency in the transportation network including emergency contacts, transportation hubs and surface street routes into the community. Additionaly, we have identified short-term solutions to improve the capacity and operation of existing routes into Magnolia. The final report summarizing the plan is here.

Concurrently, we've kicked off the long-term Magnolia Bridge Planning Study, which will develop a permanent alternative tot he existing Magnolia Bridge structure. SCJ Alliance, a local engineering firm, brings a new lens to evaluate solutions that address the current and future transportation needs in the area and a solution that can be constructed. We intend to keep the public engaged throughout the process. Email us with questions at magnoliabridge@seattle.gov or subscribe here to receive occasional project updates.

Project Overview

Environmental impacts over the last two decades have weathered the Magnolia Bridge. We perform regular maintenance and frequent inspections on the bridge to ensure it is safe to use. However, in the long term, we will need a replacement for the bridge. In 2002, the year after the Nisqually Earthquake, we received a grant to identify a Magnolia Bridge replacement that would meet the community needs and the environmental conditions in the area. The team began with more than 20 options. Many of these options were eliminated due to environmental restrictions, community concerns, and engineering limitations. Five alignments were presented to the community. Ultimately, the community's desire drove the decision for a parallel bridge south of the existing Magnolia Bridge. Unfortunately, we've been unable to obtain adequate funding to complete the design and construct the preferred option.

We'll use the recommendations from the 2002 Magnolia Bridge Replacement Study as a basis for identifying short-term, and permanent solutions for accessing Magnolia should the bridge be closed. Our primary goals throughout the study are to identify financially feasible solutions and maintain a level of service similar to the current traffic conditions.

Funding

This planning study is funded by the 9-year Levy to Move Seattle, approved by voters in 2015. Learn more about the levy at www.seattle.gov/LevytoMoveSeattle.

History

The Seattle Department of Transportation (SDOT) and the Federal Highway Administration (FHWA) released the Final Magnolia Bridge Replacement Project Environmental Assessment (EA) in July, 2015 as part of the National Environmental Policy Act (NEPA). The EA examined the potential effects of the project on the natural and built environments. However, due to a lack of funding, the project is currently on hold.
