SC&MB - La Selva Beach Trestle
NOTE: The original structure has been demolished. Stacy & Whitbeck has installed a modern analogue of the structure with the same overall design but modern construction techniques and mitigation.
Bridge is comprised of 9 deck girder spans of varying lengths, affixed to steel towers or bents. Three primary spans are mounted to towers, whereas the approach spans are affixed to the bents.
In 2012, a survey conducted by J.L. Patterson and associates on behalf of the the Santa Cruz County Regional Transit Commission [SCCRTC], which found the bridge structurally deficient, with "significant section loss with portions of columns having either 100% loss of member flanges or webs" and "the lateral and longitudinal bracing is for all intents and purposes non-existent in many of the towers". As such, the bridge is unfit for rail traffic, and the SCCRTC thusly decided the bridge will be reconstructed "from the footings up", and opted to install a bridge constructed by the firm Stacy & Witbeck.
As of August 2014 work on a replacement bridge has begun. All parts were fabricated offsite by S&W so therefore all that will be done on-site is assembly. Removal of the original bridge began in September, 2014 and installation of the replacement bridge's girder sections was complete by December 5th, 2014.
