Airport Trail tunnel was one of three City of Calgary projects to receive top honours at the 2013 American Concrete Institute (Alberta Chapter) Award of Excellence banquet on May 31.
Latest project update - October 2013
On July 31 The City of Calgary turned over the last section above the Airport Trail tunnel—the area underneath the west perimeter road—to the Calgary Airport Authority (CAA). The section above the tunnel under the east perimeter road was turned over on June 30. The City has now met all the tunnel turnover dates required by the CAA. This is one of the final major milestone markers in moving toward the completion of the Airport Trail tunnel.
Transportation General Manager Mac Logan talks to reporters about meeting all the tunnel turnover dates.
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.
36 Street N.E. now has limited access to-and-from Country Hills Boulevard (CHB)—EB CHB (right turn) onto SB 36 Street, and NB 36 Street (right turn) onto EB CHB.
NOTE: At this time, there is no left turn from WB CHB onto SB 36 Street and no left from NB 36 Street onto WB CHB.
Motorists can still use Métis Trail as the main an alternative route.
Construction activity is also taking place on Airport Trail and Barlow Trail which may impact traffic heading to and from Calgary’s International Airport.
Even though the tunnel structure has been poured, backfilling of the storm tank and portal walls are complete and fireproofing inside the tunnel is substantially complete, work continues on many fronts. Both east and west control rooms at each portal end have been installed and various electrical and mechanical works within the control rooms are ongoing. Inside the tunnel, electrical and mechanical work such as pulling streetlight and fan power cables, installing junction boxes, air quality monitoring equipment, light fixtures, fire alarm wiring/hardware and a P.A. system, continues.
Work along Airport Trail and the intersections at Barlow Trail and 36 Street, as well as the widening of Airport Trail between Deerfoot Trail and Barlow Trail from four to six lanes, has started and will continue over the summer months.
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. Completed 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 overall tunnel project 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.
