Four years ago, the Transportation Corridor Agencies (TCA), the operators of The Toll Roads, celebrated the grand opening of the Oso Parkway Bridge. The bridge provides drivers with a direct connection between the 241 Toll Road and Los Patrones Parkway.
The bridge was a multiagency collaboration between TCA, Caltrans and the County of Orange designed to improve safety, mobility and connectivity in the region. TCA provided funding for the nearly $40 million project.
Oso Bridge is a 210-foot-long overpass that features six lanes of travel (three in each direction), dedicated bike lanes and wide sidewalks to enhance safety for students and families accessing Tesoro High School.

Oso Parkway Bridge gives drivers mobility options. Thanks to the Oso Parkway Bridge, drivers traveling to or from the 241 Toll Road and Los Patrones Parkway can do so seamlessly by driving under the new bridge rather than having to stop at a busy, signalized intersection – enhancing safety and traffic operations.
The project received local and regional recognition with awards from the Orange County Chapter of Women’s Transportation Seminar (WTS-OC), as well as the Orange County branch and the Los Angeles section of the American Society of Civil Engineers (ASCE).


For TCA, the greatest recognition comes from drivers who have seen surface street congestion eased, commute times lowered and access to businesses, restaurants and recreational activities increased.
