Côte Saint-Luc Rd. eastbound will be reduced from three lanes to two lanes between Cavendish Blvd. and Borden Ave. from Monday, July 15 to Wednesday, July 17, 2019. The city’s contractor will be repairing two catch basins on that block. A catch basin (sometimes called a storm drain) is a drainage structure with the sole function of collecting rainwater and snowmelt from streets.
