(Updated — Monday, December 18, 3:01 p.m.) Construction on this part of Bloor Street West and the DRT detours continue until December 31 19.


For about one year, Durham Region contractors will be building a new trunk water-main under Bloor Street between Albert Street to Stevenson Road South during this, the second, phase of a project to improve the security of the water-supply system.

According to the Region, improving and expanding the water-supply system helps to “meet the increasing demands for new development in the Region and [is] currently being planned to connect the Whitby and Oshawa water distribution networks.” The entire new water-main extends between Wilson and Stevenson Roads South.

The Region and City previously closed Bloor Street East between Ritson Road South and Albert Street — and DRT detoured buses — overnight from Thursday, August 7 until Friday, August 8, 2015 and from Tuesday, September 9 until Tuesday, October 28, 2015 during the first phase of this project. It also closed Ritson Road South north and south of Bloor East — and DRT detoured buses — from Friday, November 6 until Sunday, November 8, 2015.

During another year, the Region will work on the third phase of the project — installing the new main under Bloor East between Wilson and Ritson Roads South.
