The Arizona Department of Transportation and the town of Clifton are working together to address vehicle and pedestrian safety concerns on US 191 through the town.
Information about various options to slow nonpeak traffic on the highway was shared at an open house held in Clifton on June 25. The potential changes, if selected, would be added to the scope of work for a drainage and sidewalk improvement project that is also under design.
That project is intended to eliminate stormwater ponding on the highway and adjacent properties, reconstruct existing sidewalks and ramps to meet current standards of the Americans with Disabilities Act (ADA), and add street lighting at the intersections of US 191 and Second and Seventh streets.
US 191 serves as the primary connection between Clifton and the Freeport McMoRan copper mine in Morenci, as well as the nearby city of Safford. During shift changes at the Morenci mine, commuting workers routinely cause congestion and delays on US 191 through Clifton, but during nonpeak hours, motorists often exceed the posted speed limit.
Various approaches to reducing vehicle speeds on US 191 during nonpeak hours are being considered at the request of the Clifton Town Council and the changes being considered will be shared with the public at the open house, along with a number of other options considered that will not be pursued.
Some options that have been considered will not be pursued because they fail to meet legal requirements, won't be effective or are prohibitively expensive.
To address concerns of the Town Council, ADOT tested temporary traffic-calming devices in selected locations for one week in May. The effectiveness of those devices was assessed by ADOT traffic engineers, and public comments were collected to understand community opinions of the devices.
Information about the testing of the temporary devices, as well as other potential changes to the highway, will be discussed at the June 25 open house. Changes under consideration include
- permanent installation of a speed table in front of the U.S. Post Office.
- possible use of a rapid flashing beacon at the speed table location.
- installation of radar speed feedback signs.
- adjustment of the posted speed limit and striping and use of rumble strips at key locations.
- curb bulb-outs — extensions of curb and elevated sidewalk — at the intersection with Second Street
Comments from the public are an important part of the decision-making process as ADOT and the town of Clifton move toward potential solutions to the vehicle and pedestrian safety concerns. Please share your thoughts on these potential solutions by clicking on the comment link on this page.
