Rivian's Waypoint chargers have started to open in Michigan with the first ones opening at Holland State Park.

Apparently some 15 such Rivian Waypoints are already up and running and the network was officially launched with Gov. Gretchen Whitmer attending the event held at Holland State Park, at one of the locations where a new charging station was added. She is quoted as saying

This partnership to install charging stations in our state parks speaks to the collaborative approach we are taking to grow our economy and address climate change head-on through clean, reliable energy.
These charging stations along the Lake Michigan EV Circuit build on our rich Pure Michigan tradition of exploration and bringing together communities and businesses to ensure that we honor our past as the place that put the world on wheels and continue to invest in our workforce as we lead the transition to electric vehicles.
The plan is to have 30 Rivian Waypoints operational along the coast in order to create a Lake Michigan EV Circuit that will help fill important gaps in the EV charging network that’s already in place in the area. Another goal is to allow visitors to drive their electric vehicles from one state park to another and have the possibility to charge in a more remote place.
