According to a Detroit News article earlier this week, 95% of the real estate has been acquired, and construction might begin yet this year. Perhaps overly optimistic, but who knows?
I have not yet hosted a meet, but I would certainly do so for this project. It occurs to me that two separate meets would be appropriate, one at the height of construction activity, another to celebrate the project completion and personally inspect the final product.
The timetable remains somewhat elusive, but the project itself has never been this certain. I would like to encourage all Road Enthusiasts who do not yet have the necessary documents for border crossings to make the effort. A passport is the gold standard, but an Enhanced Driver's License would also be sufficient. There may be other options that I am not familiar with.
If 2020 is the right year, I hope the weekend of July 4 (on a Saturday) would be the right time. It is a fun time to visit Detroit and Windsor. They host a joint venture Freedom Festival (Canada Day is July 1st). There is always a big fireworks display over the Detroit River.
If 2021 is the optimum time for construction, the calendar week would be even better. Canada Day on Thursday, Independence day on Sunday.
Pencil these onto your social calendar, and be sure to get your international travel documents.
