Tidal causeway and bridge connecting islands
Northstar Hydro, Inc. provided hydrologic, hydraulic and scour analysis to Maine DOT’s contractor for preliminary design for the Oceanville Bridge replacement in Stonington, Maine. This bridge connects two islands and allows tidal interchange in the channel that divides the two islands. Flow is complex and analysis included modeling, on-site monitoring and data review to determine how flow tides interact with the existing and proposed bridges. The first photo shows the site location and the second photo shows the existing bridge.
