West Calgary Ring Road



1. What are the project hours?

  • The project hours for the construction of the Southwest Calgary Ring Road (SWCRR) are Monday to Friday from 7:00 a.m. to 10:00 p.m. and Sundays and holidays from 9:00 a.m. to 10:00 p.m.
  • The hours for the north gravel site and haul road are Monday to Friday from 8:00 a.m. to 8:00 p.m. and Sundays and holidays from 9:00 a.m. to 8:00 p.m.
  • Select activities may occur outside of these hours with special permission from Alberta Transportation.
  • There are other third-party contractors carrying out construction in the Transportation Utility Corridor (TUC) that may work under different hours.

2. What are the construction noise restrictions?

  • Construction activities are subject to a noise level restriction set by the Province of an average 65 decibels over a 24-hour period.

3. Who do I contact if I have a noise concern?

4. What are the noise level restrictions for the SWCRR?

  • The SWCRR is located within the Province’s TUC and is subject to provincial noise attenuation guidelines.
  • Alberta Transportation has adopted a noise level of 65 decibels over a 24-hour period (A-weighted) measured 1.2 metres above ground level and 2 metres inside the property line (outside the highway right-of-way).
  • Additional resource:

5. Are the Province’s noise level restrictions the same as the City of Calgary’s?

  • No, the provincial guidelines for noise attenuation in urban areas are different than those used by the City of Calgary; however, they are consistent with the policies used by the City of Edmonton and other urban areas.
  • The provincial guidelines have been used to determine the need for noise mitigation measures along the ring roads in Edmonton and Calgary.
  • The guidelines are regularly reviewed to ensure they remain applicable.

6. Will there be noise mitigation along the SWCRR (e.g., berm or wall)?

  • The construction of any noise mitigation measures is determined by the Province’s guidelines, which require that road noise be addressed if it reaches higher than 65 decibels averaged over a 24-hour period.
  • KGL is currently undertaking a noise modelling study that will determine where measures may be required along the project corridor to meet these guidelines.
  • If the noise is expected to be above this threshold, then KGL is required to construct a barrier.
  • Further to this, once the roadway is open, Alberta Transportation will be doing a noise monitoring study to confirm that noise levels are not exceeding the Provincial guidelines.
  • During the operating period (30 years) Mountain View Partners will monitor noise levels and provide additional mitigation if the threshold is exceeded.

7. When will you know which areas qualify for noise mitigation?

  • The result of the KGL noise modelling study should be available in late 2017, while the detailed design is expected in 2018.



1. How is dust controlled?

  • Dust at all work sites will be monitored regularly during SWCRR construction.
  • Mitigation measures include watering, application of dust palliatives, use of seeding tackifiers, and other site-specific measures.

2. Who do I contact if I have a dust concern?



1. How do I report outages or suggest changes to traffic signals in the project corridor?

2. Why are the speed limits so low along the project corridor?

  • The speed limits in construction zones are set for the safety of workers and the travelling public:
    • There may be workers or equipment in close proximity to the road.
    • There may be construction activity, road conditions or alignment changes that are different than the past or not apparent to the travelling public.
    • There may be equipment entering and existing roads.

3. How is KGL minimizing debris tracked onto public roads?

  • Gravel strips or cattle guards are placed at access points to construction sites to remove mud from haul truck tires.
  • Haul trucks are swept before leaving sites to ensure they are clear of gravel.
  • KGL works with subcontractors to ensure that they adhere to all applicable regulations for hauling, including use of truck bed coverings.
  • A regular street sweeping program has been initiated on roads within the TUC.
  • KGL has retained the services of a 24/7 road maintenance company that performs spot cleanings on roads as needed.

4. How can I report debris on the road?

5. How do you determine the location of haul roads along the project corridor?

  • Haul routes are determined by project needs, access throughout the construction site and safety considerations to remove heavy truck traffic and equipment from public roads.
  • In some cases, traffic signals may be installed along major roads in order to allow haul trucks to safely enter and exit site access points.
  • Truck and equipment operators are provided with route maps to avoid residential neighbourhoods and congested areas.


Light Pollution

1. What is being done to limit light pollution from the SWCRR?

  • There are a number of changes being made to lighting along the SWCRR, compared to other portions of the ring road.
  • This includes shorter light stands, use of LED lights, reduction of lighting to minimum levels, and removal of upward facing lights on directional signs.
  • The LED lights are also recessed into the cover, so they only direct light downwards.


West Calgary Ring Road

1. What is the West Calgary Ring Road?

  • The West Calgary Ring Road is the final portion of Calgary’s ring road that runs from Highway 8 at 101 Street to Highway 1 at Stoney Trail.

2. What is the timeline for construction of the West Calgary Ring Road?

  • A timeline and delivery method has not been announced by the Province.
  • This project is not currently in the Province’s Three-Year Construction Program; however, it is in the Four Year Capital Plan.
