Ontario Widening Highway 401 from Mississauga to Milton

Ontario announces plans to expand 401 from Mississauga to Highway 25

Ontario has announced plans to widen 18 kms of the 401  from the Credit River in Mississauga to Regional Road 25 in Milton.  The expansion project includes adding HOV lanes in each direction and widening the existing six lane configuration to:

  • Twelve lanes from the Credit River to Winston Churchill Boulevard
  • Ten lanes from Winston Churchill Boulevard to Highway 407 ETR / Highway 401 interchange
  • Twelve lanes from Highway 407 ETR / Highway 401 interchange to James Snow Parkway
  • Ten lanes from the James Snow Parkway to Regional Road 25

Widening the 401 will relieve congestion, allow for a more efficient transportation and flow of goods.  It will help accommodate continued population and employment growth in the region. “This will reduce traffic gridlock and make it easier for commuters to spend more time with their families,” Halton MPP Indira Naidoo-Harris said.

Ontario is making the largest infrastructure investment in hospitals, schools, public transit, roads and bridges in the province’s history. To learn more about what’s happening in your community, go to Ontario.ca/BuildON.
