Rossi Would Bring 21st Century Bridge Repair Technology to Toronto

Mayoral Candidate Calls For Rapid Bridge Replacement, End To City Hall Foot-Dragging

TORONTO, ONTARIO--(Marketwire - Sept. 15, 2010) - Rocco Rossi expanded upon his vision to get Toronto moving forward with an announcement at the Jameson Avenue bridge today where he committed to bringing rapid bridge replacement technology to Toronto.

"As with my Toronto Tunnel, I will take full advantage of new technology to get the job done faster and with less disruption," said Rossi. "We've got eleven major bridge projects coming up and we can't afford to use anything but the latest technology."

Rapid bridge replacement is a construction technique whereby a bridge is assembled in an off-site location without disrupting traffic before being erected in replacement of a deteriorating bridge. Because the process of raising the bridge into place takes a matter of hours, traffic disruption is minimal.

"When I replace bridges as your Mayor, we will build the bridge off-site, creating good local jobs. We won't disrupt traffic. And we will get these things in place, quickly and safely," said Rossi.

Rossi blasted the Jameson Avenue bridge project, not due to be finished until November 2011 as another example of City Hall foot-dragging.

"They have said that we don't need to dream big for Toronto, we just need to manage it," said Rossi. "The problem is that they have not even been competent managers. 

Toronto needs a leader, said Rossi, "who will do the big things, like the Toronto Tunnel, and can do the smaller things, like rapid bridge replacement."

Backgrounder: Rapid Bridge Replacement

The Problem:

The City of Toronto continues to use out-dated and out-moded methods of infrastructure development and repair that contribute to:

  • Cost over-runs;
  • Project delays; and,
  • Traffic congestion.

The Jameson Avenue Bridge is one of eleven bridge rehabilitation projects scheduled across the city (see Appendix 1).

Construction on the Jameson Avenue Bridge began in May 2010 and is not scheduled to end until November 2011. In the meantime, traffic has been disrupted and the Gardiner Expressway's capacity has been reduced by up to 50% at the point where construction is occurring(1).

The Solution:

The Province and other municipalities have embraced rapid bridge replacement technology to address the problems associated with traditional bridge construction.

Rapid bridge replacement is a construction technique whereby the structure of a new bridge is assembled at a non-disruptive location nearby the old structure. Once built, the new structure is put into place using heavy lift technology(2).

The technology has been used successfully across North America and Europe.

Examples of rapid bridge replacement projects in Ontario include:
  • Clyde Avenue Bridge, Ottawa(3):
    • Construction began August 2nd, 2008.
    • Construction completed August 3rd, 2008.
    • Total construction time: 24 hours.
  • Island Park Bridge, Ottawa(4):
    • Construction began August 11th, 2007
    • Construction ended August 12th, 2007
    • Total construction time: 17 hours.
  • Aberdeen Avenue Bridge, Hamilton(5):
    • Construction began July 30th, 2010
    • Construction ended August 3rd, 2010
    • Total construction: 51 hours.
The benefits of rapid bridge replacement include:
  • Significantly shorter traffic disruption times.
    • Jameson Avenue Bridge (18 months) compared to Island Park Bridge (17 hours)
  • Reduced costs associated with traffic congestion and disruption.
    • The rapid replacement of the Island Park Bridge saved $2.4 million which otherwise would have been lost due to congestion(6).
  • Reduced greenhouse gas emissions produced by idling vehicles stuck in traffic.
  • Creation of new, well-paying jobs.
    • The rapid replacement of the Aberdeen Avenue Bridge created 415 new jobs(7).

  • Denewood Pedestrian Bridge
  • Bloor-Islington Bridge
  • Mount Pleasant Bridge
  • Gardiner Road Bridge
  • Gardiner/Bathurst/Strachan Bridge
  • Dufferin Street Bridge at the Gardiner
  • Dufferin Street Bridge at the CNE
  • Fort York Pedestrian and Cycle Bridge
  • Lakeshore Boulevard Bridge west of Jameson Avenue
  • Jameson Avenue Bridge over the Gardiner
  • Lakeshore Boulevard Bridge at Dunn Avenue
