The City of Montreal says it will take at least a day longer than anticipated to replace a water main on Décarie Boulevard at the corner of Côte-St-Luc Road.
Until Monday night only one of three lanes will be open southbound on Décarie, and officials expect there could be traffic bottlenecks during morning and evening rush hours.
The work began last Tuesday and was planned to be completed by Sunday.
However, workers say they need at least another day to finish the work.
Police officers will be on site to direct traffic.
