The Mariner Overpass Structural Rehab & Intersection Upgrade involves targeted rehabilitation of the Mariner Way Overpass—including concrete repairs, expansion joint replacement, and drainage  improvements—along with transit ramp and intersection upgrades such as traffic signal works, median modifications, pavement repairs, and new markings. The work is delivered under a unit-price contract, largely at night, with comprehensive traffic and environmental controls to minimize impacts while extending the service life of the infrastructure.
