Purpose/Challenges:

The existing two lane overpass of Fall Hill Avenue that runs over I-95 needed to be widened to four lanes. MSE abutments, constructed in two phases were needed to complete this work.The first phase consisted of constructing a new two lane bridge with MSE abutments just south of the existing two lane bridge. Once completed, the existing bridge was demolished to make way for the second half of the new bridge, also supported by two new MSE abutments.

Solutions:

To enable the new bridge to be constructed in two phases, a temporary wire faced MSE wire wall was required to be built perpendicular to the face of each Abutment at the center line of the new bridge structure.

Services Provided:
  • MSE Abutment (two phases) and one Stand Alone MSE Wall including Leveling Pads
  • MSE Wire Faced Temporary Walls at each Abutment
  • Precast Coping on MSE Abutments and Wall, including Leveling Concrete on top of Walls
