I know I will probably never use the Gordie Howe Bridge considering I have no desire to be in Canada again and if my travels take me to the east coast I will go around the south side of Lake Erie.
From your location, isn't the Blue Water Bridge the better/quicker option to get to Ontario than the Gordie Howe (or any other Detroit area bridges) in the first place?
It depends on where in Ontario I'd be going to.
I’m thinking of London eastward, including the Toronto area and Niagara Falls (to re-enter the US if going to Upstate NY/New England).
London would be quicker to go over the Blue Water Bridge from where I'm at (I'm in Saginaw) it's about a 3 hour or so drive not counting the time you spend at the border to clear customs. Toronto and Niagara Falls same thing. Like if I was heading to Boston or somewhere near there it's still almost 2 hours quicker to go through Canada but I'm also thinking of the travel due to the pandemic.
Now get this, if I was heading to NYC it's about 700 miles and 11 hours to go via I-75, US-23, Ohio Turnpike, I-80 across PA and NJ. To go through Canada which is actually the shorter route by about 15 miles takes an extra half hour and yet another route consisting of also going through Canada but doing a slightly different routing in New York is one more mile but an extra half hour as well.
To go to Buffalo through Canada is about 6 hours and 360 miles. To go on the south side of Lake Erie it's about an extra hour and 100 miles. My whole point is that if you don't have to be in Canada it's not an outrageous amount of time difference to just stay in the United States and go around the south side of Lake Erie.
