YELLOWSTONE NATIONAL PARK – Update: as of Aug. 15 at 9:00 a.m., the road between Mammoth Hot Springs and Norris Junction is back open. National Park Service crews worked through the night to locate and temporarily repair a major water line break that supplies water to all of the Mammoth Hot Springs facilities. The park will plan a permanent fix on the line this fall once visitation and vehicle traffic subsides.  

The road between Mammoth Hot Springs and Norris Junction is temporarily closed on Aug. 14 due to a major water main break in Mammoth Hot Springs.

The water main break is located under the road between the Mammoth Hot Springs Terraces and the YCC Camp. This water main provides all potable water to the Mammoth Hot Springs area. Currently, crews are removing asphalt from the road to locate the break.

It is unknown how long the temporary road closure will be in place but visitors must be aware that at this time there is no access between the north and south parts of the park and must detour outside of the park for access between the North/Northeast and South/West/East entrances. Visitors to Mammoth Hot Springs can still access the Terraces via the North and Northeast entrances only. Refer here for a map of the closed area.
