The Billy Bishop Toronto Airport pedestrian tunnel, a Canam-Buildings’ project, won an award at the December 2nd banquet of the Ontario Concrete Awards (OCA) held in conjunction with the Concrete Canada trade show, part of Construct Canada.

An innovative pre-support technique was used to drill seven 1.85-metre-diameter interlocking drift bores, or mini tunnels, above the main tunnel crown using boring machines. The drifts allowed excavation to continue under the crown, while enabling the tunnel to hold its shape. It was the first time in Canada that such a technique was used.

The Billy Bishop Toronto Airport pedestrian tunnel connects the Bathurst Street Terminal to the airport located on an island just opposite. This tunnel allows users to make the crossing in about six minutes and is a complement to the current ferry service.

Canam-Buildings provided 1,201 m2 of steel deck for the construction of this tunnel.
