Southwest Calgary Ring Road

Preliminary work for the Southwest Calgary Ring Road (SWCRR) project has been underway since July 2016. Full construction on the project started in spring 2017. The project is expected to be complete in fall 2021.

The $1.42 billion project involves construction between Highway 8 (near the Elbow Springs Golf Club), and Macleod Trail SE, including reconstruction of Glenmore Trail from Sarcee Trail to east of 37 Street. This portion of the ring road is approximately 21 kilometres long. An additional 10 kilometres of connector road upgrades will be included in the overall SWCRR project.

NEW Gravel Operations and Asphalt Processing

The SWCRR project has two gravel operations, one located at the south end of the project, within the project footprint—the 162 Avenue interchange will eventually be located here—and one at the north end of the project, within the footprint of the future West Calgary Ring Road.

The south crushing operation is located over 400 metres away from the nearest residence and is expected to finish operations by January 2019. Alberta Transportation is overseeing the work to ensure that noise and dust are effectively mitigated.

The north crushing operation is 150 metres from residences, and as such, the dust, noise and air quality at that location is regularly monitored and all provincial and project requirements and guidelines are being enforced.

An infrastructure project of this size requires asphalt processing locations in close proximity to construction. One is located near the south gravel operation, more than 700 metres from the nearest home. Alberta Transportation worked with the contractor to locate the north asphalt plant in an area with the least impact to area residents. The north asphalt processing plant is located at West Strathcona, south of Highway 8, between 1 and 1.5 kilometres from the nearest home. The contractor has been adhering to Alberta’s Code of Practice for Asphalt Processing Plants, which lays out environmental requirements and manages emissions.

Southwest Calgary Ring Road Gravel Operations Health Impact Assessment

In February 2017, Alberta Transportation commissioned a geo-environmental consultant to complete a Health Impact Assessment of the gravel mining and crushing operations near the community of West Springs.

The assessment reviewed:

  • The forms of silica typically found in Calgary aggregate and their associated risks.
  • Existing regulatory guidelines associated with exposure to fine particulate silica dust.
  • Possible health risks associated with the gravel operation adjacent to the community of West Springs.

The assessment and its findings can be found here. Alberta Health Services reviewed the proposed dust mitigation and monitoring plans and indicated the gravel operation should not negatively impact the health of nearby residents, if the plan is effectively implemented. To date, Alberta Health Services (AHS) has found air quality monitoring results to be reassuring and adequate to protect human health.

Alberta Transportation is working closely with the project contractor to ensure that effective mitigation measures are implemented.

Fine particulate matter, silica, dust, wind and noise levels are regularly monitored throughout the duration of the gravel operation to ensure public health and welfare.

Air Quality and Noise Monitoring
Updated air quality and noise monitoring data will be posted on the Alberta Transportation website monthly. Results obtained to date indicate that the air quality and noise is generally well below all established thresholds. In some instances, the thresholds were exceeded. We are aware of these exceedances, and in addition to construction activity, they are related to:

  • Overall air quality in the City of Calgary.
  • The B.C. wildfires, which put the entire City of Calgary in an air quality warning.
  • The close proximity of another contractor’s work on the West Calgary Connector utility lines.
  • High winds.

Where air quality exceedances occurred, immediate action was taken to quickly identify the potential cause and address it. Alberta Transportation will continue to monitor air quality to prevent future exceedances. Should this occur again, efforts such as sprinklers or tarps, altering work practices, or cessation of work will be repeated to reduce the dust.

A low-noise crusher is being used to minimize noise impacts on local communities. An average threshold of 65 decibels is applied during working hours. Monitoring data indicate noise from the gravel operation is generally well below this threshold. On January 30, 2018, a fourth air quality monitor was added near the community of West Springs. The solar panels powering it failed, and a new wind power generator has been installed to ensure power going forward.

In some instances the threshold was exceeded. Most exceedances occurred at the monitor on the west side of the gravel operations, approximately 300 metres away from the nearest residences, and are influenced by the close proximity of another contractor’s work on the West Calgary Connector utility lines. In addition to gravel crushing operations the exceedances closer to residences are related to:

  • Construction of the east-side berm
  • Tree planting
  • High winds
  • Relocating the monitors, which created anomalies in the data

Alberta Transportation will continue working with contractors to identify opportunities to minimize noise impacts.

Air quality and noise monitoring data is posted here.
