Machias Dike Bridge Project

Bridge #2246 carries Route 1 over the Middle River in the Town of Machias, Maine. The Middle River joins the tidal portion of the Machias River at/immediately downstream of the bridge. The existing bridge consists of four box culverts within an embankment structure (causeway). The culverts are constructed of timber and stone masonry and are pproximately 130 feet long, 6 feet wide and 5 feet high. Each culvert has top‐hinged flap gate installed on its seaward side. The causeway is constructed of timber cribbing with rubble and earthen fill and is over 1,000 feet long.

The culverts and the flap gates are deteriorated. MaineDOT is studying options to rehabilitate or replace the bridge.
