Highway Maintenance Culvert Repair Project

Caltrans District 7 in Los Angeles is planning a highway maintenance project to rehabilitate ten deteriorated culverts along Interstate 5, Interstate 5S, and State Route 14 within specified post miles. The work will involve installing cure-in-place pipe liner or concrete invert paving and repairing joints and inverts to restore structural integrity and ensure compliance with current safety standards. The project aims to address the loss of serviceability in these culverts, which has led to risks of erosion, water ponding, and potential flooding, thereby enhancing overall roadway safety. No new right-of-way will be acquired, and no public utilities will be relocated, making the scope focused solely on in-situ repairs. The project is forecasted for release with the primary point of contact being Hannah Tram, Environmental Scientist, who can be reached via phone or email for inquiries. All work will occur between PM R51.43 and 80.00 on I-5, PM C45.49 on I-5S, and PM R28.93 and R48.61 on SR-14, with the forecast posted in July 2026.
