Canadian collapse injures five workers

Work on a single-span bridge in Canada halted just hours from the completion of its concrete deck last week when the scaffolding supporting it collapsed.
Fifteen construction workers were pumping and screeding the final 30m3 of a 260m3 pour on the deck for the two-lane bridge, when its single 18.3m span collapsed into the river below.

Five workers were left injured from the failure of the £330,000 bridge, which crosses a small creek between Lucknow and Amberley in central Canada, 200km west of Toronto.

A County of Bruce Highways Department spokesman said: "We are pleased to report that to the best of our knowledge there are no serious long-term injuries. We are now working with the various authorities and the contractor to determine an appropriate path forward."

Work on the new bridge began in July and was scheduled to finish by the end of September. It was already running 10 weeks behind schedule due to setbacks during the demolition of its predecessor.
Contractor Allen-Hastings had recently completed the forming of the deck and the placement of reinforcing steel.

Both the county engineer and designer BM Ross confirmed that it was the scaffolding that had collapsed. It is thought the wet concrete would have weighed in excess of 500t.

The Ontario Labour Ministry is now investigating the cause.
