Construction Inspection Services - Peace Bridge Improvements

This project reconfigured access between the U.S. Peace Bridge and I-190 in Buffalo. A new NB ramp (Ramp D) now provides a direct connection to I-190, including a new structure over the CSX railway tracks. Portions of Ramps C and N were rebuilt to accommodate the new ramp. Porter Avenue Bridge over the CSX tracks and I-190 was reconstructed and includes a roundabout with two realigned ramps. The Riverwalk trail was realigned and includes new bridges over the CSX tracks and I-190.The roadway going through Front Park was eliminated and the park was restored to its original configuration.

This was a multiyear staged construction project. The bid included a time component for completion. The contractor worked all winter and two shifts during the summer of 2015 and 2016 to meet the scheduled completion date and claim the incentive bonus.
