How was the proposed route between the City of Greater Sudbury and Estaire determined?
MTO staff and their consulting engineers, in consultation with the public, determined the preferred route that would minimize the potential natural, social, economic, or cultural impacts associated with the four-laning of the highway. As with the south end study, the work included an investigation to determine if there would be disruption to archaeological or heritage sites, water bodies, fisheries, or wild life. Noise levels were also examined. The process of route selection followed the requirements of the Environmental Assessment Act and was approved by the Ministry of the Environment in 1999. New information came to light concerning the section to four-laning from the City of Greater Sudbury to just south of Highway 537 during the engineering phase design that presented an opportunity to improve upon the previously approved route. An amendment was issued to the previous EA approval.
