Drivers on Highway 401 westbound near Waterloo should plan for overnight slowdowns later this month, with two left lanes scheduled to close for roadwork. (therecord.com) The closure is set to begin at 10 p.m. on Saturday, April 26, 2026, and continue until 6 a.m. on Monday, April 28, 2026. The affected stretch is on Highway 401 westbound in the Waterloo area. (therecord.com) Ontario 511 lists roadwork and construction on provincially maintained highways and says its service provides up-to-the-minute information on closures, incidents and travel conditions. That makes the 401 work one of the disruptions drivers and carriers are expected to monitor in real time before leaving. (511on.ca, 511on.ca, 511on.ca) The timing matters because the work runs through two nights on one of Ontario’s busiest freight and commuter corridors. Even partial lane reductions on Highway 401 can back up weekend traffic, overnight deliveries and early-morning trips into Waterloo Region. (therecord.com, 511on.ca) The Record’s closure notice was generated from Ontario 511 data, which the Ministry of Transportation uses to publish scheduled short-term repairs and maintenance on provincial highways. Ontario 511 separates those entries from incident closures, which cover crashes and other unplanned events. (therecord.com, 511on.ca, 511on.ca) For drivers, the practical advice is simple: check Ontario 511 again before the weekend of April 26, because posted highway work can shift as crews and conditions change. The road stays open, but with two westbound lanes out overnight, the trip past Waterloo is likely to take longer. (511on.ca, therecord.com)
