It is also important to note that San Diego Roads & Highway Projects help infrastructure meet the demands of today’s traffic demands, while also meeting current seismic and safety standards.
San Diego County has 51 pedestrian or bicycle bridges and 772 highway pedestrian bridges, meaning they are used by both vehicles and pedestrians. Approximately 300 bridges are located within the City of San Diego.
With an expected completion date of mid-2022, the West Mission Bay Drive Bridge Project will replace the existing 4-lane bridge with a 6-lane bridge having a northbound and a southbound Class I bike facility and pedestrian sidewalks. The project includes a bike path on both bridges, and roadway widening and improvements along Sports Arena Boulevard, West Mission Bay Drive and the westbound I-8 off-ramp.
As one of San Diego’s busiest thoroughfares, the West Mission Bay Drive Bridge provides access to and from the Pacific Beach and Mission Beach neighborhoods. Traffic and population have changed greatly since the original bridge was built in the 1950s. Designed to handle 40,000 daily trips, a 2009 study revealed daily traffic volumes exceeded 64,000 vehicles a day. Caltrans evaluated the more-than-60-year-old bridge and found it to be functionally obsolete.
The estimated total cost of the project is $149 million with an estimated construction contract cost of $111 million. The project is fully funded through the Federal Highway Administration Highway Bridge Program, $4.9 million from Sea World traffic mitigation and $13.5 million from a Transnet Extension fee.
