Limited travel will be permitted through Sylvan Pass between the hours of 6 a.m. and 10 a.m. Visitors headed westbound into the park should leave Cody no later than 8:30 a.m.
Travelers headed east out of the park toward Pahaska Tepee and Cody need to be across Fishing Bridge by 9:15 a.m. There could also be delays because water from the melting snow has saturated the ground along and beneath a section of the East Entrance road east of Sedge Bay along the northeast shore of Yellowstone Lake. A section of the roadbed has washed out (as shown above), leaving approximately 60 feet of the eastbound lane unsafe for travel. This section of the road will be limited to one lane travel only with the traffic flow regulated by flaggers or automated traffic lights. Visitors can expect some temporary delays on this section of road for several weeks until extensive repairs can be made.
During the closure periods, the section of road between the East Entrance and a point just west of Lake Butte will be closed.
Why the limited hours? Safety. Park avalanche forecasters have determined that the safest travel window across the pass will be during those early morning hours between 6 a.m.
and 10 a.m. Forecasting staff are closely monitoring weather, snowpack, moisture and all of the complex factors that go into determining the safety of opening the road for public travel.
A limited travel window schedule is expected to remain in place until enough snow melts along and above Sylvan Pass to eliminate the avalanche hazard to those traveling on the East Entrance road.
