Background informationProject Created: December 20, 2017

Project Name: Sarah Mildred Long Bridge Replacement (NH/ME)
Year in Operation: 2018
Sector: Transportation
Subsector: Roads, Bridge
Status: In Operation
Type: New Facility
Description: The project is a joint venture between the Maine and New Hampshire Departments of Transportation, with MaineDOT serving as the lead. The two states have entered into a Three Bridge Agreement covering their jointly owned bridges spanning the Piscataqua River. This is a complete replacement of the 1940 steel lift bridge that crosses the River between Portsmouth NH and Kittery ME. The design includes the first-ever use of precast-concrete segmental towers on a lift bridge. The new bridge will carry one lane of vehicle traffic in each direction, with a set of railroad tracks down the middle. In an innovative design, the railroad tracks will be stored in a much higher rest position, providing significantly higher clearances and reducing movements of the lift structure by more than 60%. The design also includes innovative tower piers that sustain vessel impact without a large separate fender system.
