General Project Information

The contract to build the Gut Bridge was awarded to Cianbro Corporation, Pittsfield, Maine on June 30, 2014.  Their bid for the project came in at $10,995,622. The project includes the bridge replacement and construction of an operator’s house, new traffic warning systems, and some approach work.   

Cianbro will begin to mobilize to the site Sept 8, 2014 and will be constructing the new retaining walls/abutments that are adjacent to the existing bridge.  This will, at times, require alternating, one-way traffic. Motorists should expect delays. The project will shut down in mid-January, 2015 due to federal in-water work restrictions.  The project will re-mobilize in 2015 after the community weekend celebration scheduled for July 17-19th. At that time, the contractor will complete preparations for installing the temporary bridge and implement the channel closure which is scheduled to begin September 10, 2015.

During the 213 days allowed for the channel closure, we will open the temporary bridge to traffic, demo the existing bridge, construct the new bridge and remove the temporary bridge.  It is anticipated that the new Gut Bridge will open it to traffic in April, 2016.  After that time, work will continue including constructing the approaches, dirt work, paving, etc.   The contract completion date is November 15, 2016, though MaineDOT is optimistic that it will be completed during the summer months.
