The SML replacement project is a joint venture between the Maine and New Hampshire Departments of Transportation, with MaineDOT serving as the lead. This project is part of a "Three Bridge Agreement" between Maine and New Hampshire to address their jointly owned bridges spanning the Piscataqua River. The other two bridges are the "high level" bridge that carries I-95, and the Memorial Bridge that links the communities of Portsmouth and Kittery, and offers vehicle, bike and pedestrian travel.
- The design process began in 2013 and construction started in January 2015.
- The project is scheduled to be completed by the summer of 2018.
