Road improvement project resumes on CO 7

March 22, 2019 - Northeastern Colorado -

ESTES PARK – Colorado Department of Transportation and Flatiron Constructors have begun preparation work on Colorado Highway 7 after a winter break. Full-scale operations are scheduled to resume in early April, weather permitting.  

Tree removal was the first spring task on the $13 million project that aims to repair flood damage from 2013 when it became a major route in and out of Estes Park due to closures on US 34 and US 36. Heavy trucks and increased traffic caused damage to the road.

Next, crews will continue repairing and replacing culverts along CO 7 around Mary’s Lake. Roughly 40 culverts, nearly half, were completed last year in addition to 90 percent of the in-town intersections slated for upgrades.

Lexington Lane is the remaining intersection that requires improvements with the goal of addressing it this spring. Those improvements included better accessibility for people with disabilities such as curb ramps and sidewalk tie-ins. No in-town work will take place between Memorial Day and Labor Day to accommodate for busy summer tourism.   

The CO 7 project also includes 12 miles of road repaving, which will be the primary focus for 2019. Last year crews began widening the road to create at least four additional feet for bicyclists. The new bike lanes will start at Lily Lake and connect to the existing bike lanes at St. Malo’s Chapel on the Rock.


  • Full-scale operations will begin the first of April and go until October.

  • Normal working hours will be from 7 a.m. to 7 p.m., Monday through Friday. In special cases, these hours may be extended.

  • In-town construction will not occur between Memorial Day and Labor Day.


  • Single lane closures with up to 15-minute delays
