PHOENIX — Motorists traveling along US 60 between Phoenix and Globe next week need to plan ahead or allow extra time as the Arizona Department of Transportation continues blasting work as part of an improvement project to build a new passing lane and widen roadway shoulders east of Superior, approximately 65 miles east of downtown Phoenix.

The construction of the two-mile-long climbing lane from Devil’s Canyon to Oak Flat (mileposts 231-233) will require two full closures of US 60 for up to 90 minutes from 9 a.m. to 10:30 a.m. and again from 1 p.m. to 2:30 p.m. on Tuesday, Dec. 22.

There will be no blasting closures scheduled from Christmas Eve through the New Year’s Day holiday weekend. Blasting will resume the week of January 4-8 and traffic alert will be issued at a later date.

Crews will also be working Monday through Wednesday night (Dec. 21-23) from 8 p.m. to 4 a.m. Pilot cars will be used to guide vehicles through the work zone while crews remove blasting debris. Motorists should plan on up to thirty minute delays.

Traffic on eastbound US 60 will be stopped east of Superior (milepost 227) and traffic on westbound US 60 will be stopped at the Top of the World, west of Miami (milepost 235), until the blasting work is completed and the roadway is reopened after all debris is cleared. Law enforcement officers will be stationed at each closure to assist with traffic control.

Approximately 30 minutes prior to each blast, motorists should be prepared for possible delays and lane closures as crews set concrete barrier prior to each scheduled closure.

Motorists seeking an alternate route can consider state routes 77 and 177, which is approximately 68 miles long. Motorists headed to the White Mountains region, including Show Low and Springerville, can also take State Route 87 through Payson and travel east on State Route 260 as an alternative.

ADOT will work to minimize the traffic impacts as much as possible, including scheduling some nighttime work.

There will be narrow traffic lanes, wide-load restrictions and a reduced speed limit through the work zone. Flaggers and pilot cars will be used at different times throughout the project.

Drivers are asked to use caution, watch for construction equipment and personnel, and allow extra time for your commute.
