City, Airport Authority finalize agreement

A lease agreement between The City of Calgary and the Calgary Airport Authority (YYC) has been reached, which sets out the terms and conditions for The City to access YYC land to construct the Airport Trail tunnel.  This project will extend Airport Trail from Barlow Trail to 36 Street N.E. under the airport runway and provide an east-west connector and future LRT right of way for commuters and travelers. 

With this agreement in place, Calgarians can expect to see work on the Airport Trail tunnel started by the end of June with an expected completion date in 2014.  Work will include:
  •  Construction of the tunnel under the new runway;
  • Widening Airport Trail between Deerfoot Trail and Barlow Trail to six lanes; and
  •  Extending Airport Trail through the tunnel to 36 Street N.E.

The estimated cost of this work is $280 million, which is within the $294.8 million funding envelope approved by Council in February 2011.  This work is considered the first stage of three for the overall Airport Trail tunnel project. 

Future additional stages of this project will be addressed as funding sources are identified and secured and subject to Council approval of the necessary budgets. 

Construction of the interchanges along Airport Trail at Barlow Trail and 19 Street N.E. and the extension of Airport Trail to Metis Trail will be the second stage of construction.  The City will contribute $50 million and YYC will contribute $20 million to the cost of the two interchanges.

The City and YYC will partner for the third stage, which includes construction on the upgraded interchanges to provide access and egress from Airport Trail to the airport when warranted by traffic levels.  Upgraded interchanges are not expected to be required for another 20 to 30 years.  This stage of construction will be shared 50/50 by The City and YYC. The City’s share will cost an additional estimated $66 million (2011 dollars). 

The tunnel is an essential part of the northeast area transportation network and is the most viable way to provide future LRT to the airport terminal from the northeast LRT line.
