Highway 6 Reopens Highway 6 will reopen this Friday, May 3rd, after a final safety inspection. A late blizzard delayed road crews, marking this as one of the latest dates on record for the highway's reopening. Rising to an elevation of 12,351 feet at Grace Pass, Highway 6 is a main link between Park City and Lake Elton. The reopening of the road is one of the annual signs that summer is near and the tourist season will soon be upon us!
