Specifications include, but are not limited to: The project consists of repairing the existing culvert bridge with the installation of expansion joints at both ends of the bridge. To support the joints, two new adjoining walls will be installed inside the existing culvert. The interior wall will become the new structural wall that supports the top culvert slab. The new exterior wall will be the abutment wall. New approach slabs and a new bridge slab (connecting to the existing slab) will support the new expansion joint along with the new walls. Demolition of the existing bridge guard rails, the existing roadway, and the existing bridge slab will also be required. All work shall be performed as shown in the construction plans prepared by TDCJ Facilities Engineering.
