East-West Tie Line Project

Valard was selected by NextBridge Infrastructure to construct the Ontario East-West Tie Line Project. The project scope included providing project management, material management, construction permitting, and the installation of approximately 290 miles of double-circuit 230-kilovolt transmission line connecting Hydro One’s Wawa Transformer Station, Marathon Transformer Station, and Lakehead Transformer Station. At the end, 1,387 towers were erected in a line of 485.5 km, 4,903.6 km of conductors were installed, 5,548 foundations were needed and employed 39 First Nation communities.

Uniqueness: The project overcame numerous challenges during construction, such as a global pandemic and a historic forest fire activity in the region.

Start of Construction: October 2, 2019

Completion Date: The last tower was up on January 28, 2022, and achieved project completion on March 2022.
