AirLINX Transit Partners, a joint venture between Aecon Construction Group and Dufferin Construction Company, has been selected to design and build a three-kilometre rail spur line from an existing railway to Toronto’s Lester B. Pearson International Airport.

The consortium will also build a rail station at the airport.

The spur line will be part of an Air Rail Link (ARL), which is being built by Metrolinx to provide express service every 15 minutes between Union Station and the airport.

Metrolinx plans to have the service up and running in time for the Toronto 2015 Pan Am Games.

Financial close on the spur line project is expected in early 2012 and construction will begin in the spring.

The spur line will branch off the Weston Subdivision (GO Georgetown corridor) and connect to the airport at terminal one.

Infrastructure and Transportation Minister Bob Chiarelli said the ARL will make life easier for residents, businesses and travelers.

“The Air Rail Link project is part of our government’s long-term infrastructure plan, Building Together, which builds on the government’s unprecedented infrastructure investments to date and will improve our economy, our environment and our quality of life.”

Metrolinx president and CEO Bruce McCuaig said the ARL will be a “vital service” delivered in time for the Pan Am Games.

“The Air Rail Link is a signature project for the Greater Toronto and Hamilton Area that will provide a great new transportation option between our nation’s two busiest transportation hubs.”

Infrastructure Ontario will announce the cost of the spur line project once negotiations are complete.
