24-Hour Temporary Signal in Place at CO 7 Next Week

July 26, 2018 - Rock Excavation will Prompt Delays and Close one Lane

ESTES PARK—Starting Tuesday, July 31, motorists can expect delays on Colorado Highway 7 around Lily Lake as crews excavate rock.

Crews anticipate having a temporary signal in place at all times for three weeks to direct traffic through the closure. Construction from Mary's Lake Road to Long's Peak Road will require an additional one-lane closure for the week. Total delay time for both closures is expected to be 15 minutes.

The 12-mile resurfacing project, which also includes drainage and bicycle-lane improvements, started in early May around Lily Lake. The entire project runs from the junction of CO 7 and US Highway 36 in Estes Park, east to Allenspark. The estimated completion date for all aspects of the project is October 2019.

After the 2013 flood, damage from increased traffic and heavy trucks using CO 7 as an alternative route compromised the integrity of the road. An allocation of money from the Federal Highway Administration has allowed CDOT to resurface the area most affected. Additionally, 40 major culverts along this route will be repaired or replaced.


Normal working hours will be from 7 a.m. to 7 p.m., Monday through Thursday, and from 7 a.m. to noon on Fridays. In special cases, these hours may be extended. No weekend work is anticipated.

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