Specifications include, but are not limited to: Third Avenue Culvert (LOP 208): The proposed repair is to pressure grout or inject epoxy into the cracks of the existing culvert at the west-facing headwall, wingwall and culvert concrete barrier. The cracks measure approximately 20 feet in length. Third Avenue Bridge (LOP 209): The headwall on the west side of the bridge structure has a horizontal crack along the length of the headwall. The proposed repair is to remove the top portion of the existing damaged headwall and wingwall and construct a new headwall supported on 18-inch cast-in-drilled-hole (CIDH) piles. The new headwall will be connected to the existing bridge structure with drill and bond dowels. The existing bridge barrier will be removed and replaced with a new concrete barrier. The existing guardrail will be removed and replaced with a new metal beam guard rail type A77Q1-A77Q5. Temporary shoring will be required during demolition work and roadway excavation.
