Oak Grove Bridge - Los Angeles, CA

- Design-Build - Seismic Retrofit of 2 freeway bridges

This design-build project consists of per­forming Seismic Retrofitting and repairs to two (2) concrete arterial highway bridges built in the late 1950’s and early 1960’s. The two bridges span two canyons. The West bridge spans the Flint Canyon which has a small stream of water flowing into the Devils Gate Dam. The East bridge spans the Arroyo Seco Canyon, which is at the outlet and overflow of the Devils Gate Dam. The implementation of proper storm water pollution control measures was critical to this project. One of the project require­ments was to implement a series positive storm water pollution control program that would insure no polluted water would come from the construction site and enter the two canyons below the bridges and road sur­faces. Another of the critical aspects of this project is to provide a safe and workable traffic control plan the will allow the project to be built and keep the motoring public informed and safe.
