Construction Kicks Off on $30 Million Oso Parkway Bridge Project

The new bridge will provide a direct connection between State Route 241 and the newly constructed Los Patrones Parkway

IRVINE, Calif. - August 22, 2018

Crews have begun work to construct a bridge overcrossing at Oso Parkway that will improve traffic flow and enhance safety for drivers traveling to and from the 241 Toll Road and Rancho Mission Viejo and surrounding areas.

The $30-million project is funded by the Transportation Corridor Agencies (TCA), the government agency that operates Orange County’s 51 miles of toll roads – State Routes 73, 133, 241 and 261. Orange County Public Works (OCPW), in partnership with Caltrans, is overseeing the construction contract led by Ortiz Enterprises.

Work on Oso Parkway will primarily be scheduled weekdays, 7 a.m. to 5 p.m., with limited night work. Separate weekend work in early September 2018 will require closing the on- and off-ramps at Oso Parkway to the 241 Toll Road to reconfigure toll equipment, repave and restripe the roadway. Drivers will be required to use Antonio Parkway to access Oso Parkway or northbound 241 Toll Road.

The two-year project is set to open in 2020. Once completed, the Oso Parkway Bridge and new roadway will allow drivers from Los Patrones Parkway to directly access the 241 Toll Road without having to use an off-ramp, wait at a signalized intersection and then use an on-ramp to access northbound 241 Toll Road.

The new Oso Parkway Bridge will include six lanes, three in each direction, with sidewalks and dedicated bike lanes on both sides. The final project will improve access, enhance traffic flow and safety and improve pedestrian access to and from the nearby Tesoro High School.

The Transportation Corridor Agencies (TCA) are two joint powers authorities formed by the California legislature in 1986 to plan, finance, construct and operate Orange County’s 67-mile public toll road system. Fifty-one miles of the system are complete, including the 73, 133, 241 and 261 Toll Roads. TCA continues to meet the region’s growing need for congestion-free transportation alternatives.
