Project Description

The Covina Boulevard et al Street Improvement Project will reconstruct approximately 325,000 square feet of pavement using approximately 9000 tons of asphalt concrete. The project will rehabilitate Covina Boulevard between Arrow Highway and the 57 freeway on/off ramps providing an aesthetically pleasing, smoother, and quieter street surface for many years. Along with the street rehabilitation the project will replace minor curb, gutter, sidewalk panels and corner ramp upgrades improving accessibility.

Construction is scheduled to start October 4, 2021 and is anticipated to take approximately three months to complete.

Where feasible this project uses environmentally friendly and cost-effective construction processes including Full-Depth-Reclamation (FDR) which recycles the existing asphalt concrete and underlying aggregate base/soil material.  The existing pavement will be pulverized or crushed, mixed with cement, and rolled into a stronger sub-base; left to cure for up to five days per lane and closed to vehicle traffic. Following the cure time, the new asphalt concrete pavement shall be constructed.

The project cost is approximately $2 million and of that cost $600,000 is SB 1 Road Maintenance and Recovery Act of 2017 funded (Gas Tax). The new pavement’s estimated useful life is 20 to 25 years.
