Highway 401 tunnel expressway could become a reality

TORONTO — A technical evaluation of a new underground car and transit expressway under Highway 401 has been launched by the Ontario government.

The idea behind the tunnel is to provide a faster route and reduce gridlock north of the city of Toronto, extending from beyond Brampton and Mississauga in the west to beyond Markham and Scarborough in the east.

Engineering services will be secured through the Ministry of Transportation, with support from Infrastructure Ontario.

The feasibility work will include:

• Examining various options to increase Highway 401 capacity, including potential routes within the existing right-of-way, number of lanes, length, and the number and design of interchanges connecting to other highways;
• refining the province’s understanding of the proposed tunnel’s economic contributions, both in the short- and long-term, as well as the project’s impact on reducing gridlock;
• reviewing best practices from similar projects in other jurisdictions;
• conducting initial soil boring testing to improve the province’s understanding of the route’s geology and its impact on design and construction;
• preparing to start the environmental assessment processes for the project; and
• conducting an initial market sounding, with feedback on any potential procurement and commercial structuring strategies.

“Ontario’s gridlock problem is leaving the average Toronto-area commuter stuck in traffic for 98 hours every year, taking up precious time that would be better spent with family, friends and loved ones, and is costing our economy $11 billion every year in the GTHA alone,” said Premier Doug Ford in a statement. “Today’s announcement is the latest step in our nearly $100 billion plan to tackle this gridlock by building and expanding highways and transit, including Highway 401, the Bradford Bypass and Highway 413, so we can get people and goods moving across Ontario once more.”

The province also stated it will begin consultations with First Nations communities about the potential project.

The new expressway would not be tolled.
