Doran Memorial Bridge


The Doran Memorial Bridge is the twin pair of steel girder bridges that carry eight lanes of road traffic on Interstate 280 over San Mateo Creek near Hillsborough, California in San Mateo County.

History

The Doran Memorial Bridge was originally known as the San Mateo Creek Bridge according to Caltrans plans. It was dedicated as the Eugene A. Doran Memorial Bridge in 1969 after the Hillsborough police officer who was killed near the site on August 5, 1959. In 2004, the bridge was rededicated as the Officer Eugene A. Doran and Marine Lance Corporal Patrick M. Doran Memorial Bridge to include his son, Patrick, who died in Vietnam on February 18, 1967 while serving in the United States Marine Corps.
It won the Medium Span, High Clearance category in the 1970 AISC steel bridges contest. Markers commemorating Eugene A. Doran and the AISC award are at the Crystal Springs Safety Roadside Rest Area off northbound I-280, approximately north of the bridge itself. The Doran Memorial Bridge was featured on the cover of the 1972 Highway Statistics report published by the Federal Highway Administration with other recently completed major structures, including the Verrazano-Narrows Bridge, the Chesapeake Bay Bridge-Tunnel, and the Cowlitz River Bridge.

Design and construction

is credited with the design of the bridge. Ciampi was commissioned to design freeway structures for I-280 by the Division of Highways in 1963.
Four arched concrete piers support the twin girder bridges. The twin bridges contain five parallel welded steel girders and are connected by a wide concrete slab. The structural steel is concealed by a slanted panel on either side. Bids were opened on April 7, 1965, for the stretch of freeway including the San Mateo Creek Bridge.
