The Manitoba government has released the findings from an extensive independent study of noise levels created by traffic using the PTH 101 (North Perimeter Highway) and PTH 59N interchange. The study concluded that noise mitigation measures are not warranted based on measurements taken and forecasted future noise levels.
“In response to public concerns, our government listened and commissioned a traffic noise study to review the impact of sound created by cars and trucks and their impact on surrounding residences,” said Infrastructure Minster Ron Schuler. “The study incorporated sound levels, traffic volumes and geographical features including ground elevation data, terrain type and tree cover. The study concluded, the levels are well within thresholds and will not have an impact on residential or outdoor recreational areas.”
The interchange at PTH 101 and PTH 59N was constructed between 2015 and 2018, fully opening to traffic on Oct. 31, 2018. The interchange construction included realignment of PTH 101 and the construction of a grade separated crossing under PTH 101 west of the interchange. The study reviewed noise levels around the interchange comparing findings to noise forecasts done prior to construction of the interchange and provided a discussion on noise criteria used by Manitoba and other Canadian jurisdictions. The study concluded that noise attenuation measures are not warranted.
An informational fact sheet on the noise criteria was also prepared to provide information on environmental noise and to outline the guidelines Manitoba Infrastructure uses for determining the need for noise reduction measures.
