  • The Perkins Bridge was the first AIT Bridge, constructed with 15″ Diameter Tubes. These tubes also featured 25% more carbon fiber, while providing twice the bending strength.
  • All sixteen arches were delivered to the job site in three packaged units and quickly unloaded with a lightweight boom truck and nylon lifting straps
  • There is no impact to the stream which connects to Belfast’s Reservoirs
  • There has been no needed maintenance to this bridge to date.
