An exception is the road from the North Entrance at Gardiner, Montana, to the Northeast Entrance at Cooke City, Montana, which remains open year-round to automobile travel.
Winter oversnow road openings are dependent on sufficient snow.
On Wednesday, March 10, Norris Junction to Madison Junction, and Norris Junction to Canyon will close. All remaining groomed roads will close to oversnow vehicle use at 8 a.m. on Monday, March 15, 1999. At this time of year, roads in the park are subject to temporary closures, and chains or snow tires may be required at times due to hazardous winter driving conditions. BACK TO TOP . Tim Gourley Hon.
