11/17 Seismic Retrofit & Rehabilitation of Laurel Street Overcrossing

Location: Sufi Mediterranean
Presenter: Peter Smith, Bridge Engineer, from T.Y. Lin International
Summary: Caltrans, in partnership with the City of San Diego, completed the seismic retrofit and rehabilitation of the Laurel Street Overcrossing in 2014. This National Historic Landmark, also known as the Cabrillo Bridge, was constructed in 1914 for the Panama-California Exposition of 1915. The bridge crosses the SR 163 Freeway and provides the only access for pedestrians and vehicles into the heart of Balboa Park from the west over Cabrillo Canyon. The bridge was identified for seismic retrofitting and needed rehabilitation to repair corrosion and to improve accessibility for maintenance inspection. Retrofit and rehabilitation work started in 2013 and was completed in time for the 2015 Centennial Celebration of the park.
