The Ontario government is giving some positive updates on a pair of construction projects that created headaches for commuters between Kitchener and Cambridge.
It said in a statement that both the Grand River Bridges project and the rehabilitation of the King Street overpass are completed, after years of construction efforts stretching as far back as 2020.
“Investments like the replacement of the Grand River bridges on Highway 401 and the ongoing work to build a new Highway 7 between Kitchener and Guelph are investments for residents and businesses in Kitchener and our broader region,” said Berry Vrbanovic, Mayor of Kitchener. “We are grateful to the province for its efforts to reduce gridlock, improve safety and ensure that commuters and goods can move more efficiently across Ontario’s Innovation Corridor.”
The provincial government said that both efforts were to reduce gridlock, as well as shorten travel times for thousands of drivers. Part of the work is to increase the number of lanes on the 401 from six lanes to 10.
Back in 2023, the province widened the 401 in Cambridge between Highway 8 and Townline Road, adding eight kilometres of new lanes throughout that stretch.
“The completion of this bridge marks a major step forward for our community by paving the way for future highway expansions,” said Waterloo Mayor Dorothy McCabe. “This update will not only ease congestion and save commuters valuable time, but it will also make travel safer for everyone.”
The Grand River Bridges carry traffic east-west through Waterloo Region, located between the Homer Watson Boulevard and King Street interchanges, with the province saying it will now help support tens of thousands of vehicles daily, including a significant share of Ontario’s commercial traffic, helping to keep people and goods moving efficiently.
“Replacing the Grand River bridge structures ensures this stretch of the 401 is ready for the growth and future projects coming to our region,” said Jess Dixon, MPP for Kitchener South-Hespeler. “It gives us the modern, reliable infrastructure that a high-volume corridor like this needs to keep people and goods moving.
Work is also still on the go to advance construction of the Frederick Street bridge, working to widen Highway 7 between Kitchener and Guelph.
