Road closures will be in effect starting Wednesday as crews prepare for this weekend’s Honda Indy.

Starting at noon, Strachan Avenue will be closed from Lake Shore Boulevard to Fleet Street.

As of 9 p.m., Lake Shore Boulevard from Strachan Avenue to British Columbia Road will be closed.

The closures will last until 11:59 p.m. on Sunday.

Motorists will only be able to access Ontario Place from Lake Shore Boulevard at the foot of Strachan Avenue.

Toronto police said the closures will have a major impact on traffic.

Const. Clint Stibbe estimates traffic on the Gardiner Expressway and other alternate routes will increase by 20-30 per cent.

“Over the next two [and] three days, I would suggest you leave much earlier. Anybody looking to attend the event, I would suggest that you take public transit to get downtown,” Stibbe said.

The Honda Indy roars into town from Friday to Sunday. It includes two full Indy car races, a local craft beer garden, food trucks, and race-related displays.
