Global professional services company, GHD, has been selected as the prime consultant for the rehabilitation projects of the Lewiston-Queenston Bridge and Rainbow Bridge.

The refurbishment of the two critical connections linking New York State and Ontario was awarded to GHD by the Niagara Falls Bridge Commission (NFBC).

GHD will oversee detailed design, administration, and contract inspection, partnering with renowned bridge construction and preservation experts, Greenman-Pedersen Incorporated (GPI), to deliver the work.

The Lewiston-Queenston Bridge and Rainbow Bridge have served as vital economic trade routes for more than 60 years. Over the years, the humid conditions of the Niagara Gorge have resulted in early signs of corrosion on the bridges’ skewback connections. GHD and NFBC aim to extend their operational lifespans and ensure seamless traffic and goods flow across the border.

Accessing the two structures presents significant challenges due to steep embankments and the swiftly moving waters of the Niagara River below. The work will involve working with 76.2-mm (3-in.) diameter anchor bolts, which are fixed and cannot be readily replaced. This will require a meticulous coating and reassembly process designed to keep the structures in service during the rehabilitation work.
