TORONTO - A pedestrian tunnel linking Toronto to the Billy Bishop island airport has reportedly reached its final design stages and construction is expected to start next month.

The president of the Toronto Port Authority Geoff Wilson has told the Toronto Star that a groundbreaking ceremony for the tunnel is set to take place sometime in February.

Wilson says that construction is expected to take two years.

Late last year the TPA announced that Forum Infrastructure Partners, which includes PCL, Arup and Technicore, will design, build, finance and maintain the tunnel.

Wilson says the 240-metre-long structure, which will run both above and below ground, will be a spectacular piece of infrastructure.

Passengers going into the tunnel from the Toronto side will enter the tunnel through a pavilion and head down through elevators.
