TORONTO—Toronto Port Authority (TPA) has announced that the seven drift tunnels that will form the crown of the pedestrian tunnel to Billy Bishop Toronto City Airport have been completed. This will allow for the next phase of construction, said the airport.

“The completion of the seven drift tunnels is a major project milestone,” said Geoffrey Wilson, TPA president and CEO. “It marks the end of an important phase of construction that takes us one step closer to providing passengers with fast and efficient access to Billy Bishop Toronto City Airport.”

The seven interlocking drift tunnels, three of which will house City of Toronto water and sanitary mains, will form a crown that will prevent water ingress. The drifts were completed using two Canadian-made boring machines dubbed “Chip” and “Dale”. The machines will now move onto the project’s next phase, which facilitates the excavation of the main pedestrian tunnel.

Construction began on the pedestrian tunnel in March, 2012. The tunnel will link Billy Bishop Toronto City Airport to the mainland and provide access for the airport’s users. Project completion is expected in mid-2014.
