Oso Parkway Bridge

The Transportation Corridor Agencies (TCA) and Orange County Public Works will replace a portion of Oso Parkway with a new bridge structure to provide motorists with a direct connection between Los Patrones Parkway (a new road connecting with Rancho Mission Viejo) and State Route 241. The new bridge will improve traffic flow and enhance safety on Oso Parkway and direct access to the 241 Toll Road will support traffic flow in the area. Construction of the Oso Parkway Bridge began in August 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 connection of Los Patrones Parkway (Opens in a new window) to the 241 Toll Road. The future bridge will contain six lanes (three in each direction), sidewalks and dedicated bike lanes for public use. Pedestrian access to Tesoro High School will be improved with the construction of a new sidewalk on the south side of Oso Parkway.

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.

Project Schedule​

Construction began in August 2018 and is expected to last approximately two years. Construction work is scheduled weekdays, 7 a.m. to 5 p.m. with limited night work. Two lanes will remain open on Oso Parkway at all times.
