Toronto-based construction company Aecon Group has announced that its infrastructure division has signed two road construction contracts in the Canadian province of Alberta.

The first contract, worth $46.7m, is with Parks Canada to twin the Trans Canada Highway in Banff National Park for a 6.2km stretch from west of Lake Louise to the British Columbia/Alberta border.

The project also includes the construction of three bridges, two over the Canadian Pacific railroad, and one to serve as a wildlife crossing over Bath Creek with wildlife fencing along the project’s length.

The other contract is with the city of Calgary for a six-lane extension to connect 96 Avenue Northeast with the Deerfoot-Trail Airport Interchange in the city.

The contract includes upgrading the interchange, constructing four new bridges over Nose Creek and the Canadian Pacific rail tracks, as well as construction of new storm-water facilities and sanitary sewers.

Work on both the projects is underway and is expected to be complete by 2012.
