It's overdue that they didn't just fold to them again.
The Ambassador would be laying in the water before their enterprise would have built new IMO. They had decades of time to do it themselves. IMO, I.e. they wanted the rights, but didn't want to reinvest in keeping it that way. Just like the plans of the past for the Middle Central building, they dragged thier feet for over the top deals till things got dropped.... and were somewhat neglectful to use and maintain the facilities and community to their potential. Fords's track record is a little better to say the least.
There will be a lot of ways across till the old bridge does finally retire. There is still the daytime automobile tunnel too.
Keeping pilings out of the water has got to be saving tons of money; the current of the Detroit River is no joke. The first international crossing, 1800s Michigan Central RR from Grosse Isle to Stoney Island to Canada got washed out from ice flow the first winter it saw. It would have awesome to see that type of aquatic infrastructure work being done here again.
Michigan is a cool place for bridges. The most bascules, lots of lifts and swings, the Golden Gate's increadibly long twin structure
the Mackinaw Bridge,
The Ambassador of course, now Gordie's, and countless smaller ones really. A pretty diverse collection.
The MC rail tunnel was first, before the car tunnel, and also used 3rd rail electric steeple cabs to shuttle the loads between Detroit and Ontario. Coal burning in the tunnel would have been a "little smokey"
