January 20, 2016

What work is starting?

What: In addition to the jet grout plant currently set-up on Donlea Drive just north of Eglinton Avenue, crews have recently installed a jet grout surplus treatment plant within the Emergency Exit Building construction site, which is adjacent to Leaside High School on the south side of Eglinton Avenue East.

Why: Construction of the headwall requires a jet grout plant to be established nearby to pump a form of concrete, otherwise known as “grout”, to the station headwall location. The grout plant on Donlea Drive is required to support operations to construct the future Bayview station headwalls.

The addition of the jet grout surplus treatment plant processes surplus jet grout before it is transported offsite to a suitable receiving site. 

When:  Starting as soon as mid to late January, 2016, the jet grout and jet grout surplus treatment plants will begin operating.  The jet grout and jet grout surplus treatment plants are expected to be in place through the remainder of Bayview headwall construction. Some work may be rescheduled or adjusted due to weather conditions and/or unforeseen circumstances.

Where and Traffic Details:

  • Donlea Drive will remain closed at Eglinton Avenue East to accommodate the jet grout plant.
  • Traffic will remain shifted to the north side of Eglinton and reduced to one lane in each direction near Donlea Drive from west of Bessborough Drive to just east of Hanna Road.  Lane closures will protect the general public and allow different construction crews to perform their work safely.
  • Left turns to and from Bessborough Drive will remain prohibited.  Donlea Drive will remain closed at Eglinton Avenue East to accommodate the jet grout plant.

Traffic delays are expected during construction. Please watch for traffic signs and take care when travelling near construction areas.
