Scope of Work
Cianbro will construct and replace the Sarah Mildred Long Bridge located on the Piscataqua River. The existing steel vertical lift bridge carries the U.S. Route 1 Bypass, providing a critical link between Kittery, Maine, and Portsmouth, New Hampshire. The new 2,800 ft concrete vertical lift bridge will be constructed at a higher elevation than the existing, with a vehicular structure stacked over a railroad level, as well as a longer lift span at 300 ft. Other differing characteristics include long open spans, fewer piers, and wider shoulders.  

Project Details
  • Construct concrete roadway and railroad superstructures
  • Construct a high quality and reliable 300-foot-long steel lift span
  • Construct four angular lift span towers 
  • Construct approach roads and intersections
  • Facilitate and foster collaboration, communication, and partnership with all members of the Project Team and stakeholders
  • Avoid and minimize Project impacts to roadway, railway, and maritime traffic, local business, and communities during construction

  

Unique Challenge



As a member of the Integrated Project Team (IPT), Cianbro will continue to work collaboratively with the Maine and New Hampshire Departments of Transportation as well as Figg Engineering and Hardesty & Hanover, on New England’s first Construction Manager/General Contractor (CM/GC) alternative delivery approach to this project. With the successful completion of preconstruction services, Cianbro will address safety, improve the project schedule, enhance overall quality, and adhere to the budget goals.
