Mountain Road 112 (M112) over Deer Creek Bridge Replacement Project

In 2023, severe winter storms and flooding caused significant damage to the two-lane bridge on Mountain Road 112 at Deer Creek, leading Caltrans to declare it in failed condition and close the structure. A temporary single-lane bridge was installed approximately 75 feet upstream, and the original bridge was subsequently demolished. The current project aims to replace the damaged infrastructure with a new permanent two-lane bridge, while also removing the interim structure that has been in place since the closure. The work is being coordinated under the oversight of the Regional Water Quality Control Board, Region 5 – Fresno, which is responsible for ensuring compliance with environmental and water quality regulations during construction. The project is forecasted to be solicited in 2026, with the place of performance located in Porterville, California, near the Deer Creek crossing. The primary point of contact for inquiries is Ernesto Garcia, Water Resource Control Engineer, who can be reached via email or phone for further details regarding regulatory requirements or project updates. This initiative is critical to restoring safe, reliable transportation along Mountain Road 112 and ensuring long-term resilience against future extreme weather events, while addressing ecological and hydrological impacts associated with bridge construction in the watershed.
