Route 7 work affects access to Colvin Run Mill

Accessing the Colvin Run Mill Historic Site may require a legendary feat until June.

As the widening of Route 7 continues, construction has started to impede easy access to the historic site, which is located at 10017 Colvin Run Road in Great Falls.

Traffic from Colvin Run Mill will turn right and continue to the east end of Colvin Run Road to access Route 7 from the east and west.

The traffic pattern change comes as crews complete utility work and other construction at the western portion of Colvin Run Road, according to a March 30 release from the county.

Site manager Julie Gurnee said signage will provide guidance for visitors.

“Coming from the west, all visitors are able to turn onto Colvin Run Road at the first entrance (Delta Glen) to enter; but to exit to Route 7, visitors will all turn right out of the site to turn onto Route 7 at the Carpers Farm/Route 7 intersection,” Gurnee said.

Here’s more from the county on the traffic changes:

Drivers entering the mill on Route 7 westbound will still be able to turn left on to Colvin Run Road at the Route 7/Delta Glen Court/Colvin Run Road intersection (west end of Colvin Run Road). Drivers entering the mill on Route 7 eastbound will still be able to turn right on Colvin Run Road at the Route 7/Carpers Farm/Colvin Run Road intersection.

The site offers classes, tours, and a general store that sells local tea blends, yellow grits, cornmeal, wheat flour and buckwheat. All grains are ground at the 200-year-old working mill. It is surrounded by trails and other outdoor amenities.

Traffic changes have routinely come up, as crews continue widening seven miles of Route 7 between Reston Avenue and Jarrett Valley Drive. Shared-use paths and several infrastructure improvements are also planned along the corridor.
