Magnolia Bridge Planning Study

Updated: July 17, 2018

What’s happening now?

Thank you for attending our 4 Magnolia Bridge Planning Study drop-in sessions and participating in our online open house and survey! The drop-in session display boards are available in the project library at the bottom of the page. We've summarized neighborhood input received and updated the Magnolia Bridge Stakeholder Group on July 17.

Later this year, once a lower-cost alternative is recommended from this planning study, it will be presented to decision-makers alongside the cost and traffic impacts of the in-kind replacement that was selected through the 2002-2008 Magnolia Bridge Study.

For answers to other questions we’ve been hearing from the community, please see this update provided by Councilmember Bagshaw. For additional details regarding our evaluation process, see the latest presentation materials below in the Project Library.

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.

Magnolia Bridge Planning

Emergency & Short Term Planning

We've collaborated with the local stakeholders to develop an Emergency Transporation 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. Additionally, we have identified sort-term solutions to improve the capacity and operations of existing routes into Magnolia. The final report summarizing the short-term traffic maintenance plan is here.


Community involvement will be important in determining the permanent solutions. Please visit this website to learn where we are in the planning process and how you can provide comments. Subscribe to receive occasional project updates.

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.
