Coastal Trail Bridge Replacement

As a result of the pedestrian bridge failure at Westchester Lagoon on June 16, 2014, Parks & Recreation contracted an engineer to complete a structural analyses of the pedestrian bridges along the entire Coastal Trail.  The Department received two final structural assessments:

1. North Lagoon Bridge Failure Assessment (4 MB)

2. Coastal Trail Bridge Assessment (remaining 4 bridges) (8 MB)  

3. Construction Documents (3 MB)

These reports provide a very detailed assessment of the cause of failure for the North Lagoon bridge as well as the current condition of the remaining four Coastal Trail bridges.

Project Status and Upcoming Replacement Schedule

As directed by the structural reports, all vehicles heavier than a snow machine or ATV are prohibited from crossing all bridges on the Coastal Trail.

In the fall of 2015, the North Lagoon Bridge was replaced. The contractor was Bristol Prime Contractors, LLC.

In the fall of 2016, the Fish Creek Bridge and Sisson Bridge were replaced. The contractor was Roger Hickel Contracting, Inc. Starting in spring of 2017, both bridges will be getting new asphalt and landscaping.


The Fish Creek and the Sisson Loop bridges on the Coastal Trail will be CLOSED DAILY from 6:30am to 5:30pm for final upgrades. Closures begin with the Fish Creek Bridge closure on Tues. May 9th to Mon. May 15th, and Sisson Bridge closure on Mon. May 22nd to Thurs. May 24th. We will be re-paving the surfaces with asphalt and doing landscape repairs. Detour signs will be posted or click links below. Thank you for your patience!


The Fish Creek Bridge will require a large detour through the adjacent neighborhood. Maps and message signs will be posted. The route selected utilizes sidewalks and crosswalks. An on-street neighborhood bicycle route is also be noted on the map.

The Sisson Loop Bridge will require an un-paved trail detour in the area of the bridge. Caution is strongly advised.

Please plan your commutes accordingly, as detours will increase travel times.
