Montrose, CO— Kinikin Road will be closed to traffic between Q72 Road and R71 Road beginning Monday morning, Nov. 20, due to concerns about the stability of the slope along the west side of Dry Cedar Creek, north of R71 Road.
The decision to close the road was made following a geotechnical engineering analysis that concluded that the slope is not stable and a catastrophic failure could occur. The analysis also found that there is no quick easy fix to stabilize the slope due to the steepness of slope, the numerous slope failures and shifting of soils near the toe of the slope, and the underlying weathered adobe shales. Sudden slope failures are not uncommon in Western Colorado where roads have been cut into hillsides consisting of adobe clay soils.
“Public safety is our top priority,” said Keith Laube, Montrose County Public Works Director. “The geotechnical report clearly indicates that the Kinikin Road slope is not stable and closing the road is the only way to ensure the safety of motorists.”
The county is currently exploring options for relocating the road around the slide area. “We are committed to finding a long-term solution to this problem,” said Laube. “Additional engineering is required when constructing infrastructure in adobe soils on steep grades. A topographic survey will be performed in the coming week that will provide the needed information for a possible new road alignment.”
In the meantime, motorists are encouraged to use alternate routes. Electronic message boards will be posted to provide motorists with advanced notice of the road closure and detour information.
