context_page_description: Aberdeen Avenue is a Lower City minor arterial road in Hamilton, Ontario, Canada. It starts off just west of Longwood Road South and east of Highway 403 as a two-way thoroughfare up to Queen Street South, where it then switches over to a one-way collector road to Bay Street South and then to another two-way section from Bay Street to James Mountain Road, a mountain-access road in the city near the base of the Niagara Escarpment.
context_section_description: The Aberdeen Avenue bridge which was constructed in 1963, was found to have advanced deterioration including on the deck, bridge containment, and non-performing bearings by the Ministry of Transportation of Ontario (MTO). The MTO decided to go with a rapid bridge replacement process, replacing the entire Aberdeen Avenue bridge deck in a weekend instead of taking the usual nine to twelve months to complete it. Reasons for the decision included minimizing disruptions to the travelling public, improved construction safety and reduced construction costs.
  MTO retained the engineering and management firm Morrison Hershfield as lead consultant for this exciting and innovative project.  The rapid bridge replacement process began the evening of July 30, 2010. Using innovative technology the old bridge was lifted away and replaced with a pre-constructed bridge that was built nearby. The process was completed on August 3, 2010. Dufferin Construction Company successfully executed the complete replacement.
  This project was the first time rapid replacement technology has been used over a major highway in Southern Ontario. It is also part of a larger project to repair or replace eight bridges along Highway 403 in Hamilton. This $35.8 million investment is expected to create or sustain approximately 415 jobs as part of the Ontario Open plan.
  On February 26, 2011, the Hamilton/Halton Engineering Week committee selected the Ontario Ministry of Transportation, Morrison Hershfield and Dufferin Construction team as the recipients of the 2011 Project of the Year in the Civil Engineering category for the Highway 403/ Aberdeen Avenue Rapid Bridge Replacement.
