U.S. Route 191 Clifton Improvements

Lane restrictions scheduled on US 191 in Clifton for three-month safety project

The Arizona Department of Transportation advises drivers to plan for the following restriction as a safety-improvement project is now underway in Clifton.

The $668,231, 95-working day project is located in Greenlee County on US 191, within Clifton, beginning at Smelter Hill and extending to Horseshoe Curve.

The approximate length of the project is 2.5 miles (milepost 162.5 to milepost 165). The work consists of drainage improvements; installation of ADA-compliant sidewalk ramps; sidewalk, curb and gutter improvements; and the installation of pavement markings and traffic-slowing measures, such as dynamic speed display signs and speed tables.

Drivers on north- and southbound US 191 should expect 10-minute delays, lane widths reduced to 11 feet, and speed limits reduced from 45 MPH to 25 MPH.

Drivers should proceed through the work zone with caution, slow down and watch for construction personnel and equipment.
