The Colorado Department of Transportation and contractor Structures Inc. will begin construction on Colorado Highway 184 on Oct. 17 to replace the Narraguinnep Canal Bridge.
The project, north of Cortez and between Lewis and Dolores, is about a mile east of U.S. Highway 491. It is expected to be completed by the end of November.
CDOT and Structures, Inc. will remove the existing narrow and deteriorating timber structure and replace the structure with a concrete box culvert, install a new guardrail, and add a new approach to the structure.
Motorists can expect brief delays with one lane of alternating traffic during working hours with both lanes open at night.
For one week, Oct. 24-30, Colorado 184 will be closed at the bridge with construction crews working around the clock seven days a week.
Local residents within the work zone will always have access to their property.
CDOT crews also will be replacing a culvert at on Colorado 184 about a quarter mile east of U.S. 491.
The maintenance operation is expected to last three days.
