Have it been decided what the US approach to the bridge be called yet? I see a few options here:
1) an x75
2) M-401 (my preference)
3) “Bridge to Canada”, without a route number.
#3 is the most likely out of that group - the ramps dump straight into the border crossing plaza before hopping on the Gordie Howe. But it will need something additional to distinguish the two crossings. Given the politics involved (the Moroun family will take any opportunity to sue if it appears the Ambassador Bridge plays 2nd fiddle to the Howe on official signage), that could be tricky, but a few ideas:
- Designate the Howe with a "To 401", complete with shield, on the Howe exit, and the Ambassador with a "To 3" designation (although ultimately you can reach the 401 from both).
- Designate the Howe as an express or a "to Toronto" route, with the Ambassador with a "local", "downtown Windsor" or other wording to suggest the Howe is the through routing
- Signage showing estimated crossing times via the Ambassador, the Howe, and the tunnel, guiding travelers to the fastest option
