Please, please (please) contact everyone you can think of to support the idea. MnDOT has contact info on the Rethinking I-94 page[1], tell your city council rep, your county commissioner, your mayor, your state legislators, the governor. Tell your friends and neighbors. It's so easy to just fall back and do the same thing we've always done; making a change is really hard and we need to show that there is support for it.
