New bridge for the St. Lawrence : air quality assessment in the new bridge for the St. Lawrence corridor : preliminary report. : En154-76/2015E-PDF

“On October 5, 2011, the Government of Canada announced that the Champlain Bridge would be replaced with a new one. The Champlain Bridge is one of the busiest bridges in Canada and is a key corridor for the regional economy and for Canada as a whole. The corridor project for the new bridge over the St. Lawrence includes not only the new bridge for the St. Lawrence but also a new bridge for Nuns’ Island, as well as the reconstruction and expansion of the federal section of Highway 15. As part of the environmental assessment for this project, Infrastructure Canada has agreed to put in place an air quality monitoring program. It was within this context that Environment Canada installed a mobile sampling station in June 2014 near the old Champlain Bridge toll station, on Nuns’ Island, in order to take air quality readings before the project’s planned start in 2015. This report is a preliminary analysis of the data gathered at the sampling station on Nuns’ Island, operated by Environment Canada, as well as from three other air quality measuring stations belonging to Quebec’s Ministère du Développement durable, de l'Environnement et de la Lutte contre les changements climatiques (MDDELCC) and the City of Montréal”--Intro.
