U.S. Highway 34 Construction Updates (Loveland to Estes Park)

Highway 34 is open this weekend! Starting Saturday, May 6 at 6am until Monday, May 8 at 8:30am! Come celebrate at the Duck Race Festival and enjoy the Visit Estes Park Fun Zone with lawn games galore and even a dunk tank!

Fall to Spring: October 17, 2016 to Early June 2017
  • A section of US 34 in the Big Thompson Canyon – between Cedar Cove and Drake (map) – will be closed to general public travel during this time period, preventing through travel on US 34 from Loveland to Estes Park. The closure is to allow major rock blasting as part of reconstruction from damage caused by the 2013 flood.

  • Travel from Estes Park to Drake via US 34 and County Rd. 43 will be open during this time.

  • The alternate routes for those coming from the north and northeast are easy detours south to Longmont and west through Lyons. These detours add less than 15 minutes to the drive to Estes Park.

    • From the center of Loveland, the detour adds 14 miles and only 11 minutes to the drive
    • From I-25 and US-34 in Loveland, the detour adds 17 miles and only 14 minutes to the drive
    • See the maps below for route options and details

Additional construction details and updates can be found on the CDOT website.
