NRC assists investigation of Nipigon Bridge failure

Ontario’s Ministry of Transportation (MTO) requested help from the National Research Council (NRC) in its efforts to determine the cause of the failure of the Nipigon River Bridge.

The bridge split in two last week causing major traffic and transport delays since it severed the Trans-Canada highway.

Starting next week, NRC’s experts will begin to analyze the damaged bolts from the bridge, that will be transported to facilities in Ottawa for further testing. Failure analysis will be carried out on the bolts used to hold together two sections of the cable-stay bridge.

“We are pleased to work with Ontario’s Ministry of Transportation to analyze the conditions that led to the bolts’ failure on the Nipigon River Bridge,” said Richard Tremblay, general manager of construction for NRC. “The National Research Council is deploying its best industry-leading experts in materials analysis and critical infrastructure and advanced equipment to arrive at a timely, safe, and lasting solution for Canadians using this important trade corridor.”
