The City of Ottawa is warning commuters to expect "significant traffic impacts" this week because of a closure on Preston Street in Little Italy.

Preston is closed in both directions from Carling Avenue to Sidney Street until Thursday, September 20.

The closure is required for a private company to connect services to the new Claridge ICON Building at Preston St. and Carling Ave.

Local businesses will remain open during the road closure.

OC Transpo Route 85 will detour in both directions, with alternate bus stop locations along the detour. Full details are available at
