Nipigon River Bridge

Highway 17 at Nipigon is a major bridge on the Trans-Canada Highway.

NIPIGON, ON

The existing bridge was a four-span steel girder bridge with a total length of 260 metres and a maximum span of 82 metres.

The bridge was demolished to accommodate the new span at the site. Western Mechanical was retained by Priestly Demolition to remove the existing structure with a reverse launch procedure.

Western Mechanical designed the reverse launch equipment in house.

Entuitive was retained by Western Mechanical to complete the analysis to confirm the structure at all stages of the reverse launch. Our team developed all the strengthening details required for the existing structure due to the changing support condition, determined the required cable staging forces to support the cantilever through all phases of the reverse launch, determined the sequencing of concrete removals to maintain adequate ballast, and reviewed the interface between the reverse launch hardware and the existing structure.
