•   Utility relocation at headwalls
•   Construction of headwalls – 6 to 8 months
•   Construction of extraction shaft at Yonge Street

Tunnel Boring Machine

The construction of new tunnels under Eglinton Avenue is done by tunnel boring machines or TBMs. Each TBM moves forward by pushing off against concrete segments. The operator advances the machine as soil is removed from the TBM face through a conveyor system. The launch pit remains active for removal of muck/spoils.

Launch of the Tunnel Boring Machine

The Eglinton Crosstown tunnel will consist of side-by-side or twin tunnels. Each tunnel will be 6.75 metres internal diameter. Initially, one machine will begin excavation; the other will follow on a parallel course soon after.

Launch Shaft Operations

To keep the tunnel safe for the crew a ventilation system pumps fresh air into the tunnel and exhaust air is moved out of the tunnel. Cranes remain in position during the mining operation; muck will be hauled out and new concrete tunnel segments will be delivered.

Tunnelling Begins

Tunnel boring machines will work beneath Eglinton Avenue, allowing business activities and traffic to continue. A single TBM will tunnel 75 metres per week, and each machine is capable of moving 500 cubic metres of earth per day. The machines are made in Toronto by Caterpillar Tunneling Canada Corporation, formerly LOVAT, a world leader in tunnel boring machine manufacturing.

Stations and Stops

Avenue Station

Local Context: Demand

Avenue Road and Eglinton represents an area of high demand for transit

There are many residences within 900m radius of the Avenue Road station.

Local Context: Land Use

There is a mix of residential, commercial and storefront businesses in proximity to the future Avenue station

The above rendering is an aerial view of the Avenue Road and Eglinton Avenue intersection, demonstrating the types of neighbourhoods and businesses this station will serve.

Secondary Entrance Location

The above rendering is a preliminary representation of the entrances and station, subject to change throughout the next phases of the design process. Passengers will travel below ground to the concourse level where they will pay their fare and then proceed down to the station platform to board their train.

Alternative Financing and Procurement (AFP)

The public-private partnership model has been underway in Canada for 20 years and has been used in 165 projects, including the Canada Line rapid transit project (Vancouver), Autoroute 25 in Montreal and the Trans-Canada highway in Atlantic Canada. In Ontario, AFP has been used for the Pan AM games athletes’ village, Ottawa Light Rail Transit, Highway 407 East Phase 1 and the Rt. Hon. Herb Gray Parkway (formerly the Windsor-Essex Parkway).

Owner’s Role Changes with AFP

Advantages of AFP include:

Increased capacity to bring projects to market.
Transfer of risk: Appropriate risks are transferred to the private sector to ensure “on time, on budget” delivery and to offer value for money. Design, construction, cost escalation, schedule delays, operations, maintenance, life cycle, and financial risk are all transferred to the private sector.
Cost certainty: AFP provides the optimal cost combination, combining capital, maintenance and life cycle costs while integrating design and construction.
