Jul. 2020 – Jan. 2022

Overview

To replace a structurally outdated 1956 bridge along California’s Highway 101, Thompson Metal Fab fabricated the new Panther Creek Bridge under Caltrans standard specifications. Environmental sensitivities in the area required a tied-arch bridge design that minimized impact to the creek below. TMF fabricated approximately 130 tons of steel using a progressive shop assembly process to verify fit before delivery. The unique design featured tie-girders with a diamond-shaped slope beneath the roadway to facilitate natural drainage. Deliveries were staged progressively from summer 2021 through early 2022 to align with the site installation schedule. The project demonstrates TMF’s ability to manage environmentally sensitive bridge fabrication with precision and flexibility.
