MassDOT Employs Acrow's Modular Steel Bridging to Maintain Traffic Flow During Major Renovation of Cradock Bridge Over the Mystic River
PARSIPPANY, NJ Acrow Bridge, a leading international bridge engineering and supply company, reports it completed the installation of a modular steel structure to maintain traffic flow during the renovation of the historic Cradock Bridge in Medford, Massachusetts. The bridge, originally built in 1637, was rebuilt in 1880 and rehabilitated in 1934. It was determined to be structurally deficient several years ago, and added to the list of state-owned bridges to repair under MassDOT's Accelerated Bridge Program.
The work on the stone arch bridge is to include demolition and rehabilitation of three concrete piers underneath the structure, and installation of renewed stone archways, upgraded utilities, new pavement and sidewalks. Remnants of an abandoned dam structure will be renovated to restore full flow of the river. It is anticipated that the project will be completed in November 2019.
Acrow's two-lane detour structure is 133 feet-10 inches at centerline with a width of 30 feet. Because two of the original bridge's four lanes are closed during the rehabilitation, it was critical to add additional capacity to handle traffic in excess of 16,000 vehicles per day including almost 300 public transit buses carrying nearly 7,000 passengers - with particularly heavy traffic during rush hour.
"It's a professional achievement to be a part of projects that facilitate the restoration of historically significant bridges like Cradock Bridge," said Randy Needham, New England Region Manager for Acrow Bridge.
Bill Killeen, President and CEO of Acrow Bridge, said, "The growing use of our components for planned repair and rehabilitation work proves the value of Acrow to deliver a safe product and keep state DOTs and contractors on time and on budget."
The bridge was purchased by MassDOT, which will reuse the components after the completion of the job. The design engineer is AECOM and the contractor R. Zoppo Corporation of Stoughton, Massachusetts.
