The expansion of an 18-kilometre stretch of Hwy. 401 in Mississauga and Milton is finally complete.
The Ontario government announced today (Dec. 12) the new lanes from Mississauga to Milton are now open.
The $640-million Hwy. 401 expansion project, which began construction in 2019, includes the widening of 18 kilometres of the 401 from Mississauga to Milton. The construction caused heavy traffic delays through the area.
But now drivers can look forward to double lanes or nearly double lanes in the previous six-lane highway.
“Highway 401 is the busiest and most congested highway in North America with approximately 180,000 vehicles on average per weekday from Credit River in Mississauga to Regional Road 25 in Milton,” said Caroline Mulroney, Minister of Transportation in a press release.
The project includes:
- a 12-lane core-collector system from the Credit River to Winston Churchill Boulevard
- 10 lanes from Winston Churchill Boulevard to the Highway 407 ETR/Highway 401 interchange
- a 12-lane core-collector system from Highway 407 ETR/Highway 401 interchange to east of the James Snow Parkway
- 10 lanes from the James Snow Parkway to west of Regional Road 25
- one new median High Occupancy Vehicle (HOV) lane in each direction
- an additional 50 spaces at the existing Mississauga Road carpool lot (now open)
- nine new, replaced or widened bridges
