Côte Saint-Luc Rd. westbound will be reduced from three lanes to two lanes between Borden Ave. and Robinson Ave. from Thursday, July 18 to Saturday, July 20, 2019 between 7:00 a.m and 2:30 p.m. The city’s contractor will be repairing 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.
