Project Overview

The QEW Credit River Improvement project extends approximately 2.6 km long from west of Hurontario Street to west of Mississauga Road in the City of Mississauga, Region of Peel. The Project consists of the construction of a new twin bridge north of the existing Credit River Bridge; rehabilitation of the existing Credit River Bridge; widening and improving the QEW; replacing the Mississauga Road overpass; Improving/reconfiguring the Mississauga Road interchange; and constructing active transportation crossings (and associated trail infrastructure) at the QEW and over the Credit River, for the City of Mississauga.

Key Tasks

The major scope of work is the construction of the new 250m long bridge, and rehabilitation of the cultural heritage existing Credit River Bridge. In addition, there is nearly 200,000m3 of earth cut/fills, substantial road design and construction, and excess soil management. The project is taking place near an environmentally sensitive wet land area, across the Credit River valley. The project also includes construction on local municipal roads and upgrades to the Region of Peel Watermain and Sanitary Sewer via microtunneling. The project includes the construction of active transportation pedestrian/bike facilities.

Unique Aspects

The project includes a dedicated Communications role to interact with the surrounding community. GIP developed the Communications Plan for the project. The project also has Quality and Environmental management systems built upon the ISO 9001 and 14001 systems. GIP developed the QMS and EMS in a manner that is self-governing, auditable, includes processes for continuous improvement, and addresses all aspects of design and construction. Inspection and testing plans were also developed by GIP for civil works. One of the key early permits to gain on the project was clearance from Trans Northern Pipeline Inc. (TNPI). GIP led the coordination with TNPI to gain clearance for the project. This included meeting with TNPI, modeling their existing infrastructure into the project’s design, and communicating work involved around the pipeline’s zone of influence. GIP also gained permission to enter, and coordinated other environmental permits like permits to take water.
