As part of the Patrick-Murray Accelerated Bridge Program (ABP) to reverse years of neglect and significantly reduce the backlog of structurally deficient bridges in Massachusetts, the Broadway Street Bridge, which connects Hanover to Hanson and crosses over the Indian Head River, was scheduled to be replaced. The original, deteriorating structure was built in 1907 and rebuilt in 1930.
Since the ABP was approved in 2008, the number of structurally deficient bridges has dropped from 543 to 458, a decline of more than 16 percent. As a result of ABP alone, 42 bridge projects are already complete, with another 69 under construction and an additional 49 scheduled to start construction within the next year. Over the course of the program, more than 200 bridges will see active construction.
To complete this program, MassDOT and the Department of Conservation Recreation (DCR) rely on the use of accelerated project development and constrution techniques. In fact, this project was value engineered and it was determined that a precast structure would not only shorten the construction schedule but also save money.
A BEBO® arch structure with a 54-ft. span, 6-ft. -8-in. rise and 38-ft. length was chosen for this project because the precast arches allowed for a rapid and cost-effective construction. The construction actually saved more than $300,000 for the taxpayers of Massachusetts. In addition, the structure promised a long life cycle with virtually no maintenance.
“The early, under budget completion of the Broadway Street Bridge project that, once again, links Hanover and Hanson is certainly welcomed news for area residents and those who travel these roads regularly” said State Senator Tom Kennedy. “I appreciate the efforts of the Administration, the Department of Transportation and all those involved with expediting the reconstruction of this bridge, and am pleased that constituents have one less detour during their morning and afternoon commutes”
The bridge reopened in October 2010, more than 20 months ahead of schedule.
