Originally built in 1882, the Hines Memorial bridge crosses over the Merrimack River between Amesbury and Salisbury, MA. The bridge features a swing span section which pivots to allow passage of barge and boat river traffic. The Massachusetts Dept. of Transportation commissioned a comprehensive redesign and rebuild of the bridge which was completed in 2012. The project included the replacement of two approach spans and the center swing span superstructures as well as the electrical and mechanical systems.
Nuttall Gear worked with BRH Engineering to develop conceptual designs for bridge’s new gearboxes. Once approved, Nuttall manufactured four different enclosed drives. All units featured fabricated steel housings and all welds were inspected by an Independent Certified Weld Inspector (CWI).
