Beartooth Highway opens for the season and last updated 2021-05-28 18:06:26-04 RED LODGE â Early Friday morning the Beartooth Highway was opened for the summer season. Crews worked throughout the spring to ensure a timely opening and the full length of the road is now accessible to vehicle traffic. The opening generally happens every year between Memorial Day weekend until Labor Day weekend. The road can be closed at any time because of severe weather or other causes. Lined up at the gates at 8 a.m. on Friday were over a dozen cars filled with people from across the country. Some woke up early and drove while others camped nearby, all to be the first one on the newly-reopened road.
