3 years of construction on the Gardiner starts here's what you need to know

The GardinerExpressway is set to undergo another round of repairwork, marking the beginning of three years of new construction and traffic.

Replacing the bridge structure, repairing the structures underneath the expressway and adding a new traffic systembetween Dufferin Street and Strachan Avenue are part ofthe second phase of the city's six-part plan to save the aging highway.

Residents traveling to and from the city should expect some of these changes to kick in starting next week, with construction primarily scheduled to take place from Monday toSaturday, from 7 a.m. to 11 p.m.

The city said the following areas will be affected:

• From March 25 to April 14, one lane will be closed for pre-construction work with intermittent overnight closures of a second lane if needed.During the eastbound lane closures, the eastbound on-ramp from Lake Shore Boulevard, east of Jameson Avenue, will also be closed.
• From mid-April until mid-2027, the Gardiner will be reduced to two lanes in each direction betweenDufferin Street and Strachan Avenue with intermittent additional lane closures as required. The eastbound on-ramp from Lake Shore Boulevard, east of Jameson Avenue, will also be closed.

However, the city said it plans to keep traffic flowing on specific days and events. All lanes will be open over the Easter weekend,March 29 to March 31, and on April 6 to April 8.Additionally,from May 2026 to July 2026,the Gardiner will be fully open to accommodate increased traffic expected duringthe FIFA World Cup.

Toronto has unveiled a new four-year construction plan for the Gardiner Expressway, which will mean lane reductions in both ways on a very busy stretch of the highway. CBCs Greg Ross has the latest details on how this will impact Torontonians.

"The Gardiner Expressway, you know, is 60 years old and it's time for us to make these major repairs,"saidJennifer Graham Harkness, the city's chief engineer and executive director of engineering and construction.

The city is unsure if this is the last major Gardiner project it will oversee, Harkness confirmed.

"We don't know what our next steps are," she said, adding the two sides are undergoing a "due diligence exercise."

"We're working to make sure that our contractor operates as efficiently and effectively as possible to get the work done."

City officials initiallysaid Tuesday it was unclear which level of government would foot the roughly $300 million bill for the rehabilitation work, after a deal brokered last fall by Toronto Mayor Olivia Chow and Ontario Premier Doug Forduploaded responsibility of the expressway from the city to the province.

On Wednesday, the city said the province has committed to covering all capital and operating costs for the Gardiner Expresswayin 2024 and 2025, including reimbursing the city for the costs of construction on this western portion of the Gardiner.

City plans to manage traffic

Roger Browne, the city's director of traffic management, says roughly 200,000 cars flow through this section of the Gardiner, and that essentially a third of the road's capacity will be cut due to construction.

He said the city'splan to manage congestion includes traffic diversions, signage, traffic agents on site and real-time monitoring that will give the citydatait can use to make changes to traffic signal timings.

It's already looking at modifying up to 60 traffic signals in the area to accommodate the changes in traffic patterns, such as at the eastbound Lake Shore Boulevard on-ramp at British Columbia Drive, he said.

In previous congestion plans, Browne said the city has even reached out to the private sector to "encourage" employers to give moreflexible work hours or get employees to consider transit and other transportation options.

"Above all else, the key message is really just to try to plan accordingly your trips and, you know, pay attention in terms of the various stages of the constructionand to try and use transit wherever possible," he said.

The city says preparatory work on this portion of the Gardiner began in November 2023.The first section of the rehabilitation project, from Jarvis to Cherry streets, was completed in 2021. The city budgeted roughly $2.2 billion for the total project, which it first approved nearly a decade ago.

Toronto driversshare doubts

Uber driver Ramanveer Singh said he drives 12 hours a day, mostly throughout the city's downtown. He said the construction will likely impact how much he drives andearns, as a result.

"It's not good for us," he said, adding he's also concerned about how the changes will affect driversafety.

Noel Lim said he travels west to Mississauga and Oakville often, and hasalready been trying to avoid closures,such as those on Adelaide Street W. He said people will likely take side streets or go on highways to avoid the construction,only to find traffic there has worsened, too.

"It'll be chaotic," he said. "Right now it's three lanes and it's still horrific, so imagine two."

Graham Stewart doubts the project will only take three years to finish.

"Probably longer, knowing Toronto construction," he said.
