Abstract: |
In October 1989, the Loma Prieta earthquake (magnitude 7.1 M) caused the upper roadway of the I-880 Cypress Street Viaduct in Oakland, CA to collapse. The project to replace the collapsed viaduct was divided into seven contracts. The Maritime Off-Ramp is one of the eleven bridges that make up one of these contracts, and is located at the intersection of Interstate highways I-880 and I-80. It is a curved steel orthotropic bridge providing access to the Port of Oakland via a U-turn from the westbound carriageway of I-80. The bridge is also known as the Horseshoe (HS) Line because of its 75-m-radius horseshoe shape. |
