Project Overview

Orange County Public Works (OCPW) has identified the need to widen Brea Boulevard to be consistent with the Orange County Master Plan of Arterial Highways (MPAH) designation of a Primary Arterial Highway.  The Brea Boulevard Corridor Improvement Project (Project) is located partially within the City of Brea and partially within unincorporated Orange County.  The Project begins at the intersection of Central Avenue/State College Boulevard and extends north  to the State Route 57 (SR-57) southbound on-ramp approximately 1,700 feet northeast of Tonner Canyon, a total length of approximately 8,000 linear feet or 1.7 miles. 

The Project involves widening Brea Boulevard from two to four lanes (two lanes each direction) between Canyondale Drive and the northern end of the corridor (approximately 1.5 miles), replacing and widening three functionally obsolete bridges, installing traffic signals approximately 1,200 feet north of Canyon Country Road and the intersection of Brea Boulevard and Tonner Canyon Road, replacing the existing signal at Canyon Country Road, modifying existing driveway ingress/egress, installing a new wildlife overpass/land bridge, adding open graded asphalt concrete paving (OGAC) at the southern end of the corridor, and providing striping and installing a new signage. Construction of these improvements would be conducted within permanent and temporary limits of disturbance along the corridor (i.e., the project limits).
