Caltrans, in conjunction with the City of San Diego completed the rehabilitation and retrofit project of the Cabrillo Bridge over State Route 163. Caltrans rang in the new Year by lighting up the arches on the Cabrillo Bridge, which is now illuminated at night.
The Cabrillo Bridge (Laurel Street Overcrossing) Retrofit and Rehabilitation Project team met its goal to complete the exterior work and restore the bridge to its original beauty in time for the Balboa Park’s Centennial Celebration in 2015. New Year’s Eve marked the unveiling of new LED arch lighting, creating a stunning nighttime view of this historic San Diego landmark. Temporary concrete barriers along State Route 163 were removed in early 2015. Work to install electrical conduit and metal ladders and doors on the catwalks continues inside the columns.
Work began on the seismic retrofit and rehabilitation project in September 2013. Work sequence and timing challenges had to be met to ensure that the work was complete before the Park’s Centennial Celebration. This included closing the bridge to vehicle traffic for six months.
Crews were faced with removing a century’s worth of sludge made up of dirt, silt and animal waste inside each of the 14 piers and two abutments. Workers had to climb into small enclosed chambers and manually shovel the mire into buckets which were hefted up and down by rope.
The exterior work to upgrade the bridge deck and repair unsound concrete was completed November 2014. Interior work included installing vertical and horizontal post tensioning steel cables, reinforcing column walls, replacing utilities, and installing a catwalk system for future bridge inspection and maintenance. A new storm drain system was also installed as part of the project.
