Thornton Creek Bridge Study

Updated: August 22, 2019

What’s happening now?

We're currently studying 4 bridges in the Matthews Beach neighborhood of northeast Seattle. The bridges each carry thousands of vehicles per day across the Thornton Creek Channel and are, on average, over 65 years old.

The bridges are showing signs of deterioration; therefore, we are exploring rehabilitation and replacement options.

Our primary goal is to identify affordable solutions that address the transportation needs of all people using the bridges. It is important to note that these bridges will remain safe to use while we conduct this study.

You can join our email list to stay up to date with latest project information. We will send emails at major milestones. If construction is required, we will work closely with community members to communicate construction schedules and details.

We recently completed two open house meetings with community members where we gathered feedback. This will be shared with the project team to inform design concepts. We will share those design concepts with the community later in the year.

The study is being conducted as part of the 9-year Levy to Move Seattle approved by Seattle voters in 2015

Project Overview

There are 4 bridges being studied during 2019. All the bridges cross Thornton Creek Channel:

  • Bridge 105 is on NE 110th St, 200 feet east of the intersection with 35th Ave NE

Bridge 105

  • Bridge 115 is on 39th Ave NE, 120 feet north of the intersection with NE 105th St

Bridge 115

  • Bridge 104 is on NE 105th St, at the intersection of 40th Ave NE

Bridge 104

  • Bridge 109 is on 45th Ave NE, 70 feet south of the intersection with NE 97th SE

Bridge 109

Various experts have visited each bridge to study their current condition and to write a report detailing their findings. These experts examined many factors, including the structure of the bridges, the condition of the soil beneath them, the flow of the creek, and the potential environmental impacts of any work.

We will complete this study in the early part of 2020 and share recommendations with the community in order to secure feedback from all interested parties.

Schedule

The elements of this preliminary study will be ongoing throughout 2019. Initial public outreach has been completed. The schedule for additional public meetings will be published here once determined.

Funding

This study has been funded through early planning. Funding for design and construction will be evaluated following a review by the Levy to Move Seattle Oversight Committee.
