Latest project update - April 2013
The Airport Trail Tunnel is a 620 metre tunnel that will run under the new Calgary International Airport runway and will extend Airport Trail from Barlow Trail to 36 Street N.E. The estimated cost for the construction of this tunnel is $294.8 million, approved by City Council in February 2011. This project is expected to be completed in May 2014.
Closure of 36 Street N.E. near the Airport
36 Street N.E. will be closed between 80 Avenue and Country Hills Boulevard beginning April 8, 2013, so that the roadway between Airport Trail and Country Hills Boulevard can be reconstructed and expanded from two to four lanes.
The closure will also allow the Airport Trail connections to be made onto 36 Street going east out of the Airport Trail tunnel. During the closure, motorists are encouraged to use Métis Trail as the main alternative.
Even though the tunnel structure has been poured, work continues on many fronts. Backfilling the storm tank and portal walls continues along with work inside the tunnel, such as fireproofing the walls and roof, electrical and mechanical work, and installing lighting and fans.
Most of the roadwork will take place in 2013, inside and outside the tunnel, as well as widening Airport Trail between Deerfoot Trail and Barlow Trail from four to six lanes.
Construction of the Airport Trail tunnel is on schedule
The Airport Trail tunnel project includes:
- Tunnel excavation - Tunnel excavation involved the removal of approximately 440,000 cubic metre of rock and earth material.
- Underground Utilities under the Tunnel Structure - Installation of underground utilities such as water for firefighting purposes and storm drainage pipes to manage storm water.
- Tunnel Structure - Concrete work on the structure itself began with the installation of the footings followed by forming and pouring of the tunnel walls and roof. Anticipated completion of tunnel structure concrete work is fall 2012.
- Life Safety Systems - Installation of communication/surveillance system, fire detection system, emergency egress accommodations, ventilation system, electrical system (including emergency/back-up), and traffic control system will progress as the tunnel structure is completed.
- Roadworks (Airport Trail / Deerfoot Trail to 36 Street N.E.) - Existing Airport Trail between Deerfoot Trail and Barlow Trail will be upgraded from four to six lanes. Airport Trail between Barlow Trail and 36 Street will be constructed to six lanes. Most of the roadworks will be constructed in 2013.
