Why has May Street been relocated?
The widening of Highway 15 is necessary to ensure transportation safety and corridor efficiency. This component of the project presents a significant challenge because it is located in a high-density urban environment. Various options were, therefore, assessed by Infrastructure Canada and its consultants.
The new configuration was devised to optimize the current space while dealing effectively with the following set of constraints: the presence of a CN railway line; a Hydro-Québec high-voltage line; a retaining wall topped by a noise barrier; the St. Pierre collector, and; access to snow dumps. Based on these constraints, Highway 15 had to be broadened mainly toward the south, that is towards May Street.
The houses on May Street could not be kept for obvious safety and environmental impact reasons (air quality and noise pollution) due to the proximity of the highway.
