  • A short section of Yellowstone National Park’s Northeast Entrance Road in Lamar Canyon (between Tower Junction and Lamar Valley) will temporarily close from 7 p.m. to 9 p.m. on June 5, 7, 8, 12, 14 and 15.
  • This segment of road will close so that construction crews can conduct safe blasting operations.  
  • During the 2022 historic flood, high water eroded the slope below this section of road rendering it not safe for use. To repair the damage, crews cut a temporary one-lane road into the hillside. Crews will blast further into the hillside this month to create a new two-lane road, which will be more resilient and able to withstand the effects of erosion and future flooding.
  • In order to avoid additional erosion, this work will need to be completed as soon as possible. Once complete, the existing one-lane road will be removed and rehabilitated.


  • The Northeast Entrance Road closed immediately following the 2022 flood due to substantial damage in five places including this section.
  • The road reopened on Oct. 15, 2022, and is open to visitor vehicle traffic year-round. It provides winter access to the communities of Cooke City/Silver Gate in Montana and to Lamar Valley, a main attraction in the park.
