1. A method of manufacturing a prefabricated link slab joint connection, the method including:
determining a size and shape of the prefabricated link slab joint connection to provide a flush connection of top surfaces of decks of respective connecting spans of a bridge superstructure, the bridge superstructure further including top flanges, webs, and bottom flanges that are under the decks;
in a controlled factory environment, setting reinforcing bars to correspond to the decks of the respective connecting spans; and
in the controlled factory environment, pouring Ultra High-Performance Concrete (UHPC) including over a central portion of the reinforcing bars;
in the controlled factory environment, curing the UHPC into the prefabricated link slab joint connection, wherein
the size and shape of the prefabricated link slab joint connection corresponds to cut-out portions of the top surfaces of the decks of the respective connecting spans, and
a top to bottom thickness measurement of the prefabricated link slab joint connection is less than a top to bottom thickness measurement of the decks of the respective connecting spans.
