Construction on Edmonton's Jasper Avenue remains far behind schedule, but there are questions over how quickly crews are getting the job done.
City councillors were assured by PCL Construction was redoubling efforts to complete the work by running two shifts with the second working to midnight six days a week.
However CBC News video taken on Jasper Avenue every evening last week well before midnight showed no workers in sight.
"It's a little baffling," said Coun. Kerry Diotte after watching the video. "We've got to push hard and make sure this thing gets done very quickly."
Paul Szczepanski, Edmonton's director of arterial roads, told CBC News the workers are trying not to disturb nearby hotel guests and people who live in downtown apartments.
"We don't want to be disrupting those folks' sleep," he said.
Business owners have long complained about the construction on the city's main downtown street saying it's hurting their bottom line. At least one retailer asked council for a break on his taxes in compensation for his losses but was denied.
