Project Highlights:
  • Accelerated Bridge Construction
  • Temp roadway on metal arch

This MassDOT project utilized the Accelerated Bridge Construction method to replace I-95 Northbound and Southbound bridges over North Ave in Attleboro, MA. The bridges are the most heavily traveled bridges in the corridor receiving more than 100,000 vehicles per day. A competitive advantage was gained with the bid by eliminating the specified temporary bridge and utilizing a temporary diversion roadway constructed with a corrugated metal arch and wire mesh retaining walls.

Bridge replacement work included the full demolition of the bridge, new concrete substructure including footings, abutment and wing walls. J.F. White utilized conventional cast-in-place methods for the substructure reconstruction. In addition, the replacement bridge superstructure included the installation of four precast bridge deck units (PBUs) comprised of steel beams with composite concrete decking tied together with closure pours.

In addition to the replacement of the bridge, the scope of the project also included: removal and replacement of related road and utility construction along the alignment, excavation and embankment, bituminous pavement, curbing, sidewalks, and pavement markings along with the installation of a new soundwall structure. The Northbound Bridge was opened to traffic 9 days early earning a Milestone Completion Incentive Bonus from MassDOT. Work on the South Bound structure will begin in the early spring 2018 followed by Final Completion in the Fall of 2018. .
