Built in 1953 and designed by renowned engineer Jean Muller, the Dominguez Elementary School Pedestrian Overpass in Carson, California, stands as one of the first post-tensioned bridges in the United States. The bridge provides a critical safe crossing over the busy Santa Fe Avenue, serving the students and staff of Dominguez Elementary.

In 2019, an overweight semitrailer hit the bridge, and the damage was very significant: post-tensioned tendons were broken and exposed, and consequently, the bridge was closed as a safety precaution.

Project Description

Dominguez Elementary School Pedestrian Overpass - Damaged Concrete

Due to the critical safety issues that the damaged Dominguez Elementary School Pedestrian Overpass caused for the local community, Freyssinet USA was contacted by the Los Angeles Unified School District to examine the bridge’s condition after the accident.

The engineers at Freyssinet inspected the structure, developed, and executed a solution in order to quickly turn the bridge back to safe operating conditions, including:

  • The exposed tendons were sealed, and the damage to the concrete was repaired using a high-strength concrete mix.
  • New concrete brackets with high-strength post-tensioned bars were attached to the bridge.
  • A new external PT tendon was added to restore the structural strength lost due to the damage in the original tendons. This new tendon was based on the Freyssinet 4C15 system.

Freyssinet achieved successful completion of this project within 4 months.

Thanks to Freyssinet’s proven concrete restoration & post-tensioning expertise, the project successfully preserved the original structure, minimized repair costs, and allowed the Dominguez Elementary School Pedestrian Overpass to reopen to pedestrian traffic in a very quick timeframe.
