CARLSBAD — Construction will begin in late January to replace a 1920s-era bridge on Carlsbad Boulevard south of Palomar Airport Road, requiring the temporary closure of a portion of the southbound side of the road. During the closure, traffic will be re-routed to Avenida Encinas. Northbound traffic on Carlsbad Boulevard will not be affected.
Work on the project was scheduled to start Jan. 25. The southbound side of Carlsbad Boulevard will remain closed until the project is completed, with the road reopening on May 28, just before the Memorial Day weekend.
During construction, southbound traffic, bicyclists and joggers on Carlsbad Boulevard will be directed east to Avenida Encinas and will rejoin Carlsbad Boulevard at Poinsettia Lane. The northbound side of Carlsbad Boulevard will not be affected.
City staff reminds the public to drive carefully in the construction zone and take alternate routes when possible. Signs will be posted around the construction site to inform the public of the road closure.
Once the existing bridge is demolished, a new concrete bridge, built to current safety and seismic standards, will be installed in its place. The new bridge will consist of precast concrete segments, which will be cast offsite, and then assembled at the construction site.
The new bridge will include two lanes for vehicle traffic, a bicycle lane, shoulders and aluminum safety rails on each side. The bridge itself will be a tan color, similar to the seawall projects built along Carlsbad Boulevard in the 1980s.
The project will also include rebuilding and extending the rock revetment on both the north and south sides of Las Encinas Creek to protect the roadway from damage during storms and high tides.
The project will be constructed by Bert W. Salas Construction, Inc., of San Diego. The project was designed by Nolte Associates.
The total construction cost is $2.6 million. The project is funded through the city’s Planned Local Drainage Area Fund and South Carlsbad Redevelopment Area Fund and is part of the city’s commitment to investing in infrastructure.
The 120-foot-long bridge spans Las Encinas Creek and was originally built by the state of California in 1913. It was expanded to its present width in 1928.
