In 2003, after considering a variety of plans involving the rebuilding of US 41/SR 90, the Corps recommended that a 3000 feet causeway be built near the Northeast Shark Slough northeast of Everglades National Park, all road fill removed that would otherwise be adjacent to the bridge, the 57 culverts that are already in place maintained, and the appropriate water flow rate maintained under the non-causeway portions of the Tamiami Trail crossing the Everglades.
