Aug. 6, 2010, Hamilton, Ont. – Dufferin Construction Company successfully replaced the Aberdeen Avenue Bridge over Highway 403 in just 51 hours on the civic holiday weekend with the use of Rapid Bridge Replacement Technology.

The operation was underway just after 9:00 pm on Friday July 30, 2010 and the new; completely replaced overpass was ready for traffic just after midnight on Monday August 02, 2010 much to the satisfaction of the Ministry of Transportation of Ontario and Dufferin Construction. The operation was ahead of the scheduled eighty (80) hour duration permitted for the work.

Rapid Bridge Replacement Technology is a construction technique in which the new bridge sections are built in an adjacent staging area while the existing bridge sections remain intact and carrying public traffic until the new sections have been fully prepped to be moved into place.

Once ready, the old sections are removed and recycled and the new sections are transported into place with the use of Heavy Lift Transporting Equipment. This is the first time that this technology has been introduced in Southern Ontario.

"The Ministry of Transportation of Ontario has taken a leadership role in adopting this technology for use in civil construction," said Wayne Lazzarato, Vice President, Dufferin Construction Company. He further added, "conventional construction methods would take longer and are not as environmentally sustainable".

Although new to Southern Ontario this technology is not new to Dufferin Construction as Dufferin Construction and the Ministry of Transportation of Ontario made Canadian history in 2007 being the first to utilize this technology in Canada when the Highway 417 overpass over Island Park Drive in Ottawa was replaced in the summer of 2007.

Dufferin Construction and the Ministry of Transportation would then repeat that same history a second time in 2008 on the same Highway 417 over Clyde Avenue, also in Ottawa; making this only the third time in Canada that this technology has been utilized successfully and the third time that Dufferin Construction has been contracted to complete the work.
