- Slip 1 is back in service as of May 16.
This project will preserve the transfer span system by replacing it with a hydraulic transfer span (H-span) design. The H-span is a moveable bridge that connects the trestle to the vessel.
Why is WSDOT
preserving the Port Townsend transfer span system?
- The structures were constructed in 1982 and are at the end of their lifespans.
- This work will increase reliability.
- Changing the transfer span will decrease operational costs. The H-span is much simpler and requires fewer staff to operate.
- This project brings the transfer span up to current seismic mechanical and electrical standards.
The End Result
The new H-span system will improve reliability and safety and reduce environmental impacts and operational costs.
Because the H-Span system is simpler and requires less staff to operate, costs to maintain the system are expected to decrease.
The project will bring the span up to current seismic, mechanical, and electical standards.
