Santa ANA mainstem, lower santa ANA river channel, reach 9-bnsf railroad bridge protection, riverside county, california

The project consists of constructing slurry concrete diaphragm walls for scour protection of the BNSF Railroad Bridge just downstream of Prado Dam on the Santa Ana River, Corona, CA. The design incorporates diaphragm walls to protect the bridge piers and abutments from long-term and localized scour with hydromill deep foundation trench excavation techniques to facilitate construction. Diaphragm walls around the existing piers will be 3' thick and varies from 32' to 47' deep. The abutment protection diaphragm walls will be 4' thick and varies from 34' to 92' deep. The deeper walls will need to be constructed under the RR bridge with approx. 25' vertical clearance. The bridge piers will also be protected with pier nose extension CIP walls up to 44' high built on new steel pile foundation. The estimated price range of construction is from $25,000,000 to $100,000,000. The estimated duration of the project is 1,460 calendar days.
