Storm Sewer Installation

traffic, the work will be performed using a micro-tunneling methodology

and one receiving shaft is required to extract the TBM

• The TBM will operate 24/7 during the tunneling operation – approx. 2 weeks

• Taunton Road will be closed at Eglinton Ave E for eight (8) weeks while the

launch shaft is in place
