Goodbye Farmington Hill, Hello New Roundabouts: US 550 & 160

The long-awaiting opening of the new interchange between US 550 and US 160 outside Durango will happen Sunday, July 14, 2024. The old route on "Farmington Hill" will be closed.

The Colorado Department of Transportation and contractor Lawrence Construction will open the new US Highway 550 alignment to traffic on Sunday, July 14. On that day, all north and southbound traffic will be shifted onto the new four-lane divided highway between County Road 302 and the US 160 and US 550 Grandview interchange, east of Durango.
“The commute to and from Durango will be a bit of a change for motorists, especially those who would normally take Farmington Hill,” Regional
Transportation Director Julie Constan said. “As motorists learn to navigate the new interchange alignment, we urge them to allow adequate travel time, slow down and pay attention to signage.” 

Motorists will be traveling on the brand new roadway of two 12-foot-wide travel lanes and over two new bridges located south of the interchange.
Roundabouts are located on either side of the Grandview bridge; including the existing Wilson Gulch roundabout to the north and the new Grandview roundabout to the south. This traffic switch will involve the closing of the existing route of “Farmington Hill,” sending motorists instead through the Grandview interchange. Soon after, the signal at the Farmington Hill intersection will be removed and the old highway will be removed and re-vegetated. 

Traffic Switch Impacts

Beginning at 7 a.m. on Sunday, July 14, motorists will encounter the following travel impacts and traffic pattern changes:

US 550 northbound - use the interchange to go east or west on US 160
Expect traffic slowing with flagging crews as barrels are moved throughout the day to accommodate the mobile operation of shifting lanes and removing striping to accommodate the traffic shift north of CR 302. Intermittent stops will occur as well The existing US 550 alignment of Farmington Hill will be closed; motorists will continue on the new northbound lanes to the new Grandview roundabout and into the Grandview interchange
Follow signs to continue east or west on US 160, or onto Wilson Gulch Road to the hospital or Three Springs community

US 550 southbound towards New Mexico - use the interchange to access US 550 south
Farmington Hill will be closed and the traffic signal inactive

Eastbound motorists will continue east past the old Farmington Hill signal and use the off-ramp onto the interchange, travel
through the new roundabouts, then south on US 550

Westbound motorists will need to be in the right lane and be prepared to take the off-ramp, west of Three Springs Boulevard,
to access the interchange, travel through the new roundabouts, then south on US 550

US 160 east and westbound - through traffic between Durango and Bayfield
The only change these travelers will notice is the signal at the
base of Farmington Hill will be inactive (and eventually removed)
