  • On Wednesday, October 21 from 8 a.m.-noon, the road between the Upper and Lower Terraces in Mammoth Hot Springs will close temporarily while crews replace a culvert from a major water line break that occurred on August 14. See map for details.
  • During this temporary closure:
    • Visitors at Mammoth Hot Springs will have access to the Lower Terraces but will not be able to travel south to Norris.
    • Visitors traveling north from Norris will be able to access the Upper Terraces but will not be able to travel further north into Mammoth Hot Springs.
  • If work is completed early, this segment of road will reopen before noon.
