Humber River Bridge

The Humber River Bridge is being expanded to accommodate four additional bridge spans and the current at-grade rail crossing will be replaced by a tunnel that will be built under the rail corridor crossing, providing a safer passage for Weston Golf and Country Club members.


  • July 31, 2014 – In July, concrete deck slabs were installed to accommodate three additional tracks on the Humber River Bridge. Remediation of the Humber riverbank is also complete. In addition, the south access ramp has been removed and temporary construction access areas under the bridge have been re-graded. What to expect in the coming months:
    • Bridge waterproofing will be completed in August.

Project Schedule

  • Construction start: April 2011
  • Construction complete: Fall 2014

What we are doing

  • Humber River Bridge
    • Bridge piers will be expanded on the north side to accommodate the additional tracks
    • The new span will effectively be double what it is today
  • Cart Path Tunnel
    • The tunnel will be built under the rail corridor crossing between holes 4 and 5 - completed
    • It will be suitable for all golfers and maintenance and will be designed to meet accessibility and safety features
  • Traffic - Installation of tie backs for the Humber River Bridge abutment structure will be installed. The nature of the soil is such that the presence of mud will be close to Weston Road. The right lane closure is to ensure safety of motorists during work.

How this will affect you

  • The construction schedule has been designed to minimize the amount of work on the Weston Golf and Country Club property during golf season
  • Crossing protection will be provided to safely escort golfers at the existing level crossing during construction
  • The landscaping will be restored to its current state
  • The 3rd hole tee box will be relocated
  • The new tracks will be continuous welded rail and the new spans will be ‘closed’ ballast decks for a quieter passage of trains


Noise and Vibration

Noise and vibration monitors have been set up along the Humber River Bridge 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).
