The north and south expansion joints for Structure 1 were installed and set in place at the end of November. Expansion joints are a critical component of a bridge, and allow the structure to expand and contract in response to temperature changes, traffic loads, and other environmental factors. Bridges are large structures made of materials like steel and concrete, which naturally expand in hot weather and contract in cold weather. Without expansion joints, these movements could cause cracking, buckling, or structural damage. Additionally, the North expansion barriers were cast in concrete on Jan 20, 2026 and the South expansion joint barriers are anticipated to be cast in concrete early February, 2026.
