CDOT -
Phillips County – The Colorado Department of Transportation and contracting partner, WW Clyde, will begin replacing five bridge structures located on US 6 and US 385 starting March 3. The anticipated completion date of the project is October 2026. The outdated bridges that will be replaced are located on US 6 and US 385, near Holyoke, in Phillips County, 13 miles west of the Colorado-Nebraska state line.
Bridge structures that will be replaced in 2025:
On US 6, east of County Road 37, Mile Point 453
On US 385, south of Colorado Highway 23, MP 279
On US 385, south of CR 4, MP 291
Bridge structures that will be replaced in 2026:
On US 6, west of CR 41, MP 454
On US 6 west of CR 43, MP 455
The updated structures will have a lifespan of up to 100 years which will minimize the need for frequent maintenance and repairs. By replacing aging bridges, this project will enhance safety for Colorado’s traveling public and address the challenges posed by deteriorating infrastructure, including bridges that may no longer meet modern safety standards. To maintain traffic flow during construction, shoo-fly detours will be built at each replacement site, allowing motorists to bypass active work zones. The detours will operate 24/7 and feature a two-lane traffic flow, except for structure A-27-AA on US 385 near MP 291. At this location, traffic will be reduced to a single lane with alternating travel guided by a traffic signal.
Travel Impacts:
Daytime work hours range from 6:30 a.m. to 7 p.m., Monday through Friday.
There will be a speed reduction of 25 MPH through the construction zone.
Shoo-fly detours will be constructed at each structure location during construction Flaggers will be in place to guide traffic.
A 12-foot width restriction will be in place & Construction vehicles will be entering and exiting the work zones – Use caution & slow down for the workers
