Although I have not seen this in the media, the Motown Museum website has the following message posted as you access the site.

The Motown Museum Board of Trustees has made the
proactive decision to temporarily close the museum through
the remainder of the year due to high volume of Covid-19
in the region.

Thank you again for your interest in visiting the Motown
Museum. We apologize for any inconvenience and look
forward to seeing you in the New Year.
