City engineers had ordered the lane closed to cars after discovering the trap door to the underground sewer entrance was cracked, making the area unsafe for drivers.
Those planning trips to or from the Island of Montreal on the weekend should note that there are several route closures to be expected. The Louis-Hippolyte-La Fontaine tunnel, the Saint-Pierre interchange and on the Highway 15 in the Atwater Avenue sector will all feature closures and should be avoided, as well as others listed below.
