A modernized Mississauga Road/QEW interchange and widened overpass are among the major tasks completed this past year as work continues on a massive undertaking to update the highway bridge over the Credit River, project leaders say.

In addition, several other key components of the QEW/Credit River Improvement Project were completed in 2025, project officials said in their most recent online update.

As they look ahead to more work to be done this spring and summer, the rest of the year and beyond, project leaders noted the following big tasks have been completed since this time last year:

The new twin bridge, currently carrying both eastbound and westbound lanes of traffic on the QEW.
A modernized Mississauga Road interchange and widened overpass.
New multi-use recreational trails, including a bridge connecting trails on opposite sides of the Credit River.
Stormwater ponds and an upgraded stormwater drainage system.
The rehabilitated historic Credit River Bridge.

The huge project is being completed to ensure traffic moves more smoothly along the QEW in Mississauga in the future, officials in charge of the work say.

In late 2024, though, work crews restoring the original bridge over the Credit River unexpectedly dug up a piece of Mississauga’s past. A number of Indigenous artifacts were discovered in the area of the QEW lanes on the original bridge, at the eastern edge of the work site.

Due to the discovery, construction at that location stopped to enable archeological investigations, which continue this year.

When those investigations conclude, project leaders say Ontario’s Ministry of Transportation will hire a construction firm to complete the remaining works, including;

The north-south pedestrian bridge over the QEW.
Underground water infrastructure.
Re-installation of noise walls.
Opening the QEW lanes on the historic bridge and the eastbound on-ramp to the QEW.

A transportation ministry spokesperson told INsauga.com earlier the Indigenous artifacts found included projectile points (arrowheads) and ceramic pottery sherds.

The transportation ministry and Infrastructure Ontario head up the QEW/Credit River Improvement Project, which carries a price tag of $313.8 million (at last estimate) and is being completed by EllisDon Corp. and Coco Paving Inc.

They were awarded the contract in late 2020 and work began the following year. No specific project completion date has been provided.

The project was first studied by Ontario’s Ministry of Transportation in 2013 and initially called for demolition of the original 840-ft.-long Credit River bridge, which was built in 1934 and expanded in 1960.   

However, public outcry and strong opposition from Mississauga city council in late 2019 changed the provincial government’s mind and it was decided the existing span, located just east of Mississauga Road, would instead be rehabilitated.  

The province said earlier that based on the feedback it received in the aftermath of the initial demolition announcement, it made the decision to preserve the original heritage structure of the bridge, which is owned by the Ontario government.
