The Highway 401 Expansion project is approximately 18 kilometres long and is located within the western part of the Greater Toronto Area, from the Credit River in Mississauga to Regional Road 25 in Milton.
The Project includes widening the existing six lane configuration to the following:
- 12-lane Core-Collector system from the Credit River to Winston Churchill Boulevard.
- 10-lanes from Winston Churchill Boulevard to the 407 ETR/Highway 401 Interchange.
- 12-lane Core-Collector system from the 407 ETR / Highway 401 Interchange to east of the James Snow Parkway.
- 10-lanes from the James Snow Parkway to RR 25.
Each section described above will include two High Occupancy Vehicle (HOV) lanes (one in each direction), with the remainder of the lanes (either eight or ten depending on the section) being general purpose lanes.
The widening will involve minor and major modifications to existing infrastructure to accommodate the proposed widening.
