From 9 p.m. Monday, August 30 until 5 a.m. Tuesday, August 31 and continuing overnight nightly, crews continue surveying and conducting utility and geotechnical investigations, including borehole drilling, as part of the Waterfront East light rail transit project. Crews work near Union Station and on Bay Street between Front Street West and Lake Shore Boulevard West overnight between 9 p.m. to 5 a.m., Mondays to Fridays. Occasionally they work weekends.

The map indicates the borehole sites. Expect future surveying for the project on Front Street West, Lake Shore Boulevard West, Harbour Street, Queens Quay East and West, Cherry Street and Parliament Street.

The work zone temporarily blocks traffic lanes. Passengers aboard buses along this route can expect delays:

• 19 Bay.

Equipment and work trucks are be present on the roadway as crews move from one borehole to the next. Drilling crews remain at each borehole site for about five to eight 8 days, occasionally following up by further visiting each location, when necessary. Expect noise and vibration resulting from drilling, hydro-vacuuming and operating equipment.

The TTC says, “The work is anticipated to be completed in three weeks”, meaning surveying and investigations continue as late as until September 18.
