Commuters in the GTA will another roadblock to deal with this starting Wednesday morning.

The City of Toronto will "intermittently" close down lanes in four separate stretches of Lake Shore Boulevard in order to prepare for the 2015 Pan-Am Games next summer. The closures will continue until mid-July.

A westbound lane will be closed from 6:30 a.m. to 2:30 p.m. ET on Lake Shore Boulevard in the following areas:

Yonge Street to just west of Rees Street

Bathurst Street to British Columbia Road

Parkside Drive to Windermere Avenue

An east bound lane in the section of Lake Shore Boulevard between British Columbia Road and Lower Spadina Avenue will close from 10 a.m. to 8 p.m. ET.

The city says the closures will be staggered to reduce traffic congestion, and construction will largely be limited to non-rush hour periods.

According to city staff, the utility work is essential to prepare the roadway as a cycling and running route for the Pan-Am Games.

“In many cases our power lines and gas lines are underground, so when they need to be improved you need to cut right into the roadway,” said Stephen Buckley, general manager of transportation for the city.
