Kingston to Quebec
Proposed extension into Michigan
As part of the Detroit River International Crossing project, the following interchanges are planned on a western extension of Highway 401 to the bridge or tunnel. They are only conceptual, and vary considerably between alternatives; the below is a rough combination of all alternatives.[3]
| Municipality | Destinations | Notes |
|---|---|---|
| Detroit, MI | Westbound exit and eastbound entrance | |
| Windsor | Malden Road | Eastbound exit and westbound entrance |
| E.C. Row Expressway, Ojibway Parkway, Huron Church Road - Ambassador Bridge | ||
| Windsor, La Salle | Cabana Road, Todd Lane | |
| Howard Avenue | ||
| Windsor, Tecumseh | ||
| Eastbound exit and westbound entrance |
Other planned interchanges
The reconstruction of Highway 401 in Mississauga is expected to add several interchanges in order to serve that fast-growing region.
Another widening project throughout Oshawa will see old interchanges closed in favour of newer ones. Construction is currently underway for a new interchange at Stevenson Road in Oshawa. This upgrade with new ramps and bridges will provide easier access to the General Motors (Canada) plant and the Oshawa Centre Mall. It will replace the outdated Park Road interchange (exit 416) that will be closed off in either 2009 or 2010.
After 407 ETR gets extended east to Highways 35/115, two other freeways will be built linking the 407 and the 401 together;
★ 407-401 Durham West Connector, near the boundary of Ajax and Whitby,
★ 407-401 Durham East Connector, in Clarington.
A new interchange at Wonderland Road in London is planned to be built around 2015.
