Magnolia Bridge Planning Study

Updated: October 31, 2018

What’s happening now?

Thanks for stopping by the Magnolia Planning Study web page. We're currently developing and reviewing cost estimates and travel times for 3 alternatives and updating the cost estimates and travel times of the in-kind replacement to provide a comparison. While the planning study won't make a recommendation, we anticipate the key findings will provide good information for the Department and our elected officials as they determine next steps. Elected officials are currently reviewing funding options and working with various partners to better understand the larger system of projects occurring in the Interbay (15th Ave W) corridor. 

We know vacations, work, kids and other obligations can keep people from attending City hosted events. So, for those unable to go to one of our four summer drop-in sessions, or to take the related online survey, we placed a mobile display at the Magnolia Community Center, at two Magnolia Farmers Market events and continue to have one at the Magnolia Library until November 26. The mobile display describes the history of the Magnolia Bridge; reiterates that the in-kind option is being included in the planning study; describes the work we've completed to-date; and shares next steps.

We've been working with the Magnolia Chamber of Commerce and Office of Economic Development and hired a consultant to conduct an intercept survey for Magnolia Village visitors. The survey will provide data about where people are coming from, what they are doing, how long they stay and what mode was used to get to the business hub. We expect to have results to share by the end of the year. 

We've extended our planning schedule to better incorporate information on the Sound Transit 3 alignment through Interbay, Expedia plans and to prepare for the permanent Alaskan Way Viaduct closure scheduled for January 11, 2019. We now expect to have results to share next spring.

For answers to other questions we’ve been hearing from the community, please see this update provided by Councilmember Bagshaw. For additional details about the planning study, 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 an alternative that would meet community needs and be well-suited to environmental conditions in the area.

The team began with more than 20 options, many of which were eliminated due to environmental restrictions, community concerns, and engineering limitations. Five alternatives were presented to the community. Ultimately, the community's preferred alternative was an in-kind replacement that would parallel the existing bridge to the south. To date, funding to complete the design and construct the preferred option has not been identified.

In 2017, we launched the Magnolia Bridge Planning Study to identify additional alternatives for the Magnolia Bridge. The study was funded by the Levy to Move Seattle. The primary goal is to identify an alternative that meets the functional needs of the existing Magnolia Bridge and the Magnolia community.

Once the alternatives analysis phase of this Planning Study is complete, a comparison of the 2 selected alternatives (the preferred alternative from the previous study and the preferred alternative from this current study) will be presented to the Mayor, SDOT directors, and City Officials. This comparison will support an analysis of the 15th Ave W corridor and how the Magnolia Bridge, Ballard Bridge, 15th Ave W, and future light rail alignment support the corridor. No decision on the Magnolia Bridge will be made until this analysis is complete.

Magnolia Bridge Planning

Emergency & Short-Term Planning

We've collaborated 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. Additionally, we have identified sort-term solutions to improve the capacity and operations of existing routes into Magnolia. Read the final report summarizing the short-term traffic maintenance plan.

Involvement

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.

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.
