ADOT briefs supervisors on Clifton paving, roundabout and microsurfacing schedules
Summary
Arizona Department of Transportation told the Board of Supervisors about paving and roundabout work in Clifton and a microsurfacing project on SR-70; ADOT said paving should be finished by late August and the roundabout should be open for use in the coming weeks after punch-list work.
Brian Jevis, assistant district engineer with the Arizona Department of Transportation's Southeast District, updated the Greenlee County Board of Supervisors on multiple ADOT projects affecting the county, including paving through Clifton, a roundabout and an SR-70 microsurfacing program.
Jevis said paving through Clifton started poorly and ADOT limited contractor working hours from the contract's 6 a.m.-late-night span to 7 a.m.-4 p.m. to reduce traffic impacts; the change reduced production and extended the schedule. He said the contractor plans to finish paving work by July and that final adjustments (manholes, striping) should be done by Aug. 22. "By August 22, say, they should be out of here, and we should be done," Jevis said.
On the Clifton roundabout, Jevis said crews poured the last concrete pavement pour but must correct some areas that are "not in spec," so the roundabout is behind schedule. He said ADOT expects the roundabout to be usable in the next several weeks after remaining drainage, striping and signage work and that lights will be operated and burned in for several weeks before final acceptance.
Jevis also said a state-funded microsurfacing (microseal) project on SR-70 from the county line through Duncan is scheduled to start in the next few weeks and should take about a month.
Supervisors raised safety concerns and speed on Smelter Hill and asked ADOT to consider speed studies. ADOT said it is conducting a Road Safety Assessment and noted that average measured speeds on the corridor were about 75 mph in some studies and that a few vehicles were clocked at more than 100 mph. Jevis said ADOT can request a speed study and work with the regional traffic group on any changes.
Jevis also described the access-permit process for changing a fairgrounds access point: applicants should submit a complete permit package including a traffic-control plan, insurance and contractor information to speed processing through ADOT's permit supervisor (Susan Puzas).
Ending: ADOT representatives said they will continue communications during construction and that the agency will attempt to reduce traffic disruption while completing scheduled work.
