Project Overview

The QEW Credit River Bridge carries the Queen Elizabeth Way over the Credit River in the City of Mississauga, Ontario between Mississauga Road and Hurontario Street. The bridge consists of a seven-span, concrete open spandrel arch structure. Originally built in 1934, the QEW Credit River Bridge is considered a Provincially Significant Heritage Bridge. The bridge was the first major bridge constructed for the future QEW, and its design set the standard for major bridges constructed along the corridor during the 1930’s and 1940’s. Although widened in 1959 a thoughtful and intentional design approach was taken, wherein original engineering principles associated with the open-spandrel concrete arch design were conserved. Today the bridge is linked to the Credit River Valley and its landmark is appreciated by those who use the Credit River for recreational purposes.

At over 80 years old, the QEW Credit River Bridge was determined to require rehabilitation due to its deteriorating condition. A holding strategy was implemented from 2011 to 2013 which repaired significant components of the structure and allowed for the completion of the 2013 Preliminary Design and Class Environmental Assessment (Class EA) study which determined the long-term rehabilitation needs of the structure and the future improvements for the QEW and Mississauga Road interchange.

The 2013 Class EA generated and evaluated various design alternatives involving three components of the QEW within the study area: QEW Credit River bridge alternatives, alignment alternatives, and interchange alternatives at Mississauga Rd. The evaluation resulted in the selection of a technically preferred alternative that is the basis for this current Detail Design undertaking. The methodology, design alternatives and evaluation are presented in the 2013 Transportation Environmental Study Report (TESR).

The current design process will build upon these recommendations and follow the approved environmental planning process for Group “B” Detail Design projects under the Class Environmental Assessment for Provincial Transportation Facilities (2000) (see EA Process).

Under the Ontario Heritage Act, provincial heritage properties, such as the QEW Credit River Bridge, require a Strategic Conservation Plan (SCP) to provide guidance on conserving and maintaining these properties. The Credit River Bridge is the first bridge that has required an SCP. A Pilot Project is underway to develop an SCP for the bridge. This Detail Design assignment will finalize the design of the bridge in a manner which is sensitive to the local context and incorporate many of the recommendations of the SCP.
