La Loma Bridge Rehabilitation Replacement Project

La Loma Bridge Rehabilitation Replacement Project

The Public Works Department of the City of Pasadena, in cooperation with Caltrans and the Federal Highway Administration (FHWA), is proposing to improve the existing La Loma Bridge to meet current seismic codes and standards. The 378-foot long reinforced concrete bridge was built in 1914 over the Arroyo Seco, a major tributary to the Los Angeles River. The existing Bridge was listed on the National Register of Historic Places on July 14, 2004. The La Loma Bridge carries two lanes of vehicular traffic, and includes 50-foot wide sidewalks on both sides of the bridge. A retrofit/rehabilitation or replacement of the existing bridge is necessary because of the deteriorated condition of the bridge, which is evidenced by the dilapidated appearance, including spalling (i.e., breaking of concrete into chips or fragments) and falling concrete, and its low sufficiency rating. The City of Pasadena, in cooperation with Caltrans and FHWA, is seeking to rectify these conditions through the use of local funds, SAFETY-LU funds, and funding to be obtained from the Federal Highway Bridge Repair and Rehabilitation (HBRR) Program. Three build alternatives are under consideration: (1) rehabilitation, (2) replacement with a box-girder design and (3) replacement with concrete box-girder bridge with decorative arches. The width for the bridge under each of the alternatives would be 42 feet, which is 4 feet wider than the existing bridge, including two standard 5-foot-wide sidewalks. The rehabilitated or new bridge would continue to provide two traffic lanes, one in each direction. Construction of the proposed project would last approximately 18 months.
