Denison Road Underpass

• Utility relocation start: January 2011
• Construction start: Spring 2011
• Construction complete: Fall 2013

• Work on the CP Rail Bridge is almost complete. On November 27, 2012 we successfully poured over 680 cubic metres of concrete for the CP Rail Bridge.
• In November 2012, excavation for the new Denison Road East began from the GO Rail Bridge towards Weston Road. Other work removal of overgrowth in the rail corridor is underway between Cobalt Street and Ray Avenue, as well as grading of the corridor on the CP Rail side. All of this work is slated for completion in April 2013 and is in preparation for signal work and reinstating the final track alignment.

How this will affect you

• The majority of the work will take place during regular construction hours.
• Some construction work may be required outside these hours. Advance notice will be provided to the surrounding community when are working outside the regular hours.
• Denison Road will be closed between Jane Street and Weston Road for a minimum of one year during construction
  • a signalized pedestrian crossing will be maintained at all times
  • there will be minimal impact to Weston Road
• Night work will be lighter construction using cranes and trucks:
  • Noise from trucks reversing will be heard
  • Lighting will be needed to maintain visibility

Noise and vibration monitors have been set up along the Denison Road Underpass project area to monitor any noise and vibration generated by the construction. This data will be posted on a weekly basis.

The following graph displays 1-hour averaged noise levels measured in decibels (dbA).
