As of 8/2020, UDOT is doing construction here (http://www.udot.utah.gov/go/gritmill). "This project will increase the availability of designated parking areas by providing 32 parking stalls, 2 handicap parking stalls, and a restroom facility. It will also align the new parking lot entrance with a realignment of Wasatch Resort Road. Construction activity is expected through October 2020." After October, someone should confirm this is what's been implemented and reflect it in OSM.
