MassDOT outlines Cut Bridge replacement plans
The state is proposing a project to replace the Blynman Canal drawbridge, shown on Friday, Feb. 24, which was built in 1907. The bridge connects West Gloucester with the island containing Gloucester and Rockport. It’s only one of two ways by car on and off the island.
“Massachusetts Department of Transportation highway officials and their project consultants have offered up a first look at what a new Blynman Bridge, aka the Cut Bridge, might look like someday.
Conceptual renderings show a bridge with a single moveable bascule span instead of a drawbridge with two spans on each side of the canal that now exists.
One concept is a simple trunnion bascule, which involves the span rotating around a single pin or shaft. The other is a rolling lift bascule, which is similar in function to the existing bridge, but with mechanical components that operate the bridge suspended above the roadway.
During a live virtual public meeting Thursday, MassDOT Project Manager Joseph Breen said the state is in the very early stages of the drawbridge replacement project with a design phase expected to last until 2027. Breen said it is also too early to give a cost estimate or a construction timeline, though two city councilors and state Senate Minority Leader Bruce Tarr of Gloucester urged that the work to replace the 1907 bridge go as “quickly as possible.”
“This bridge is a major piece of transportation infrastructure and it’s important to point out that it is really only one of two access points on to the outer edges of Cape Ann including Gloucester and Rockport and as such it’s continued viability is absolutely essential to all of us,” Tarr said…”
