Oso Parkway Bridge Project

The Transportation Corridor Agencies and Orange County Public Works will build an overcrossing bridge structure for a portion of Oso Parkway, at the southern end of the 241 Toll Road, to allow traffic from Los Patrones Parkway to travel under Oso Parkway and connect to the 241 Toll Road. Direct access to the 241 Toll Road will improve traffic flow, enhance safety, and support mobility for the region. Construction of the Oso Parkway Bridge is anticipated to begin Summer 2018.


Project Overview

Map of Oso Parkway Bridge ProjectThe Oso Parkway Bridge Project consists of constructing an overcrossing bridge structure for a portion of Oso Parkway to allow the future connection of Los Patrones Parkway to the 241 Toll Road. The future bridge will contain six lanes (three in each direction), sidewalks and bike lanes for public use; enhancing pedestrian access to Tesoro High School and providing a more efficient connection to and from Los Patrones Parkway and the 241 Toll Road.

Los Patrones Parkway is currently under construction by Rancho Mission Viejo as a four-lane transportation corridor that extends from Cow Camp Road to Oso Parkway.  Los Patrones Parkway will terminate at Oso Parkway via a northbound off ramp and a southbound on ramp. The Oso Parkway Bridge project includes constructing the roadway to connect the north end of Los Patrones Parkway to the 241 Toll Road under the bridge structure.
