The city paid a premium to expedite the Lake Shore paving work, according to officials.
Crews completed the project about three weeks ahead of schedule and about a month after they got started.
"We had worked with the contractor to expedite their schedule," says Steve Buckley, the city's general manager of transportation services. "They were flexible in terms of the hours they were willing to work."
Buckley says the city paid the contractor a premium to have crews working longer hours and on weekends.
"It really wasn't significantly above cost," he says, but he didn't yet have the numbers available.
Councillor Denzil Minnan-Wong, chair of the public works committee, says he likes the idea of paying a premium on some projects.
"Time is money and congestion costs a significant amount of money to motorists all across this city and if the price is reasonable and if we can incent construction companies to finish sooner, you can put me down for that," Minnan-Wong says.
Buckley says the city is working on determining which future projects should also work on an expedited schedule.
There is still some work to be done on Lake Shore Blvd.
The installation of loop detectors in the pavement will continue the next few weeks. But the city says this work will done with limited overnight lane closures, not affecting daytime traffic.
The loops will allow the city to automatically adjust traffic-signal timing depending on traffic on Lake Shore and the Gardiner.
