Pudding Creek Train Trestle Rehabilitation

MacKerricher State Park, CA

This picturesque redwood timber train trestle crossing Pudding Creek to MacKerricher State Park built in 1917 for the Union Lumber Co. is uniquely representative of the regional timber industry.  Originally built entirely of old growth timbers, the repair of these members as well as use of re-purposed timbers from a Santa Cruz Trestle were key to the project success. The design and retrofit included innovative and unique methods vital to protecting the habitat of endangered species. Helical piles driven through the sand to bedrock provided support in the tidal zone while minimizing disruption of the creek bed. The final surface of Trex decking and use of redwood and stainless steel cable side handrails provide modern durable elements allowing the rehabilitated trestle to serve as a pedestrian and equestrian path yet maintain its historic legacy.
