The bridge spanning the Mystic River in Medford, a suburb of Boston, Massachusetts, was built in 1637, then rebuilt in 1880 and again rehabilitated in 1934. It was determined to be structurally deficient several years ago - one of many of state-owned bridges - and was put into the state’s Accelerated Bridge Program.

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 41m at centre-line with a width of almost 9.2m.

Because two of the original bridge’s four lanes are closed during the rehabilitation, it was critical to add additional capacity to handle daily traffic in excess of 16,000 vehicles, including almost 300 public transit buses.

Acrow’s bridge solution was purchased by MassDOT for reuse after the completion of the Cradock Bridge job. Design engineer for the project is 1397 AECOM and the contractor is R. Zoppo, based in Stoughton in Massachusetts.

“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,” said Bill Killeen, chief executive of Acrow Bridge.
