Interstate 8, the vital east-west passage connecting San Diego and Phoenix, is undergoing significant pavement replacement work through the picturesque Cuyamaca Mountains writes the Southwest Concrete Pavement Association. Led by Caltrans and Project Manager Abdul Malikyar, this project aims to enhance road durability and safety along a 10-mile stretch between Alpine and Pine Valley Bridge.
More than 39,000 cubic yards of concrete are being utilized for Continuously Reinforced Concrete Pavement (CRCP) installation, ensuring a long-lasting roadway that can withstand heavy traffic and adverse weather conditions for up to 70 years. This innovative choice minimizes future maintenance needs, reducing disruptions for travelers and risks for highway workers.
Despite challenges posed by the mountainous terrain and weather delays, Granite Construction, the prime contractor, is making steady progress. The project involves lane reductions, implemented behind concrete barriers, to facilitate CRCP work while maintaining traffic flow. Additionally, upgrades to bridge railings enhance overall road safety.
The completion of Stages 1 & 2 saw improvements on several bridges and individual slab replacements. Now, Stage 3 is in full swing, focusing on CRCP installation and bridge rehabilitation. With Stage 4 underway and Stage 5 slated for completion next year, this project promises improved infrastructure and smoother journeys for commuters traversing the scenic Cuyamaca Mountains.
