I have set the closures listed on the MNdot site. Looks like it's going to be a tough area this summer. MNdot is always vague and/or late with the specific dates so it's tough to keep things current.
If you'd like to help out timing and updating the closures you could join the Google Hangout group with most of the local MN editors here https://hangouts.google.com/group/Pi0BCuLT0ohUHJ6v2. Otherwise you can just report the closures in the app and fill in as much detail as possible and we will do the best we can to update the changes.
