I am pleased to announce that this week MassDOT will perform its first “Bridge Move”.
During the past several weeks, a bridge superstructure has taken shape right next to the intersection of Route 2 and Route 2A in Phillipston. Last night, crews demolished the old bridge that carried Route 2 over Route 2A. You can see some great photos of the demolition on our Flickr page.
A superstructure is the part of a bridge that spans the roadway, river, or railroad track that the bridge crosses. Later this week, MassDOT will be moving this bridge’s new superstructure into place using remote-controlled, self-propelled trailers called Goldhofer trailers. Two of these trailers will lift the bridge superstructure from its temporary supports and carry it into its final location—the location of the superstructure we just demolished.
Now that the old superstructure is demolished, travelers on Route 2A and Route 2 must be detoured around the immediate bridge location. We expect the detour period to last approximately eight-and-a-half days, an extremely short period of impact for a bridge project. By building the replacement superstructure away from Route 2, we have limited the Route 2 impact to just the eight-and-a-half day period. Traffic on Route 2A has had some short-term lane closures for movement of equipment and personnel. Conventional construction methods would have required long periods of lane closures for Route 2, resulting in long periods of congestion.
We anticipate that we will move the replacement superstructure later this week. We will more information about when and how to view the Commonwealth’s first Bridge Move. Please visit the project website at www.mass.gov/massdot/heavyliftphillipston to learn more, see detour maps, and watch a video.
