Lambert Road Rehabilitation (Phase I) Project


OE provided design engineering services to the City of Brea to rehabilitate this aging arterial roadway that services up to 40,000 vehicles per day.  With the project area encompassing nearly 300,000 SF of pavement, OE’s design included pavement grinding and AC overlay of various depths, and replacing median island noses, custom designing rebar-reinforced ADA-compliant ramps, installing video detection at Traffic Signals, reconstructing PCC Driveways, installing 73 water valve sleeves and lids, coordinating with MWD to adjust manholes, and replacing portions of curb, gutter, and sidewalk. OE designed multiple construction details to clearly convey the design intent to the contractor. Our team also conducted an extensive drivability review and assessed post design roadway cross-falls relating to new ramp and driveway accessibility.
