SR 160 - Vashon Terminal - Timber Trestle and Terminal Replacement - Complete September 2016

Washington State Ferries upgraded the 50-year-old Vashon trestle to meet current seismic standards.


How you benefit

Improves safety
In the event of an earthquake, the main transportation corridor for Vashon Island residents will be better protected.

We installed seismic braces at 10 critical locations along the dock and replaced 200 feet of timber trestle with concrete supported by steel vertical piles.

We modified the traffic pattern and vehicle waiting lanes on the dock. These modifications remove conflict with cars and working ferry slips, making it safer for school children, pedestrians and people with limited mobility to travel to and from the ferry.


Partnerships & cooperation
Washington State Ferries worked closely with the Vashon community, Ferry Advisory Committee and local legislators on the design and construction of this project.


Total project cost: $15 million. Funding was provided through a mix of federal grants and state funding.
