PHOENIX – Daytime blasting to remove potentially hazardous rocks resumed yesterday in an effort to protect workers and motorists along State Route 77 south of Globe. SR 77 will be closed in both directions between mileposts 154-161 from 10 a.m. to 3 p.m. every Monday through Thursday.

In addition, lane closures are expected each work day from 7-10 a.m. and from 3-5 p.m. Drivers should expect delays of about 15 minutes during those times. The restrictions are expected to remain in place until March.

ADOT crews had been working at night to remove rocks that could have fallen along SR 77 near Dripping Springs. The work was switched to the safer daylight hours after a loosened 18-foot limestone boulder fell 150 feet and landed on the roadway on November 30.

The incident underscored the risk for construction crews and the potential hazard to motorists. In addition to the instability of the rock face that is being removed, blasting creates flying rock that could be dangerous to workers, especially in the dark between sunset and sunrise.

During the closures, drivers can travel SR 177 and US 60 between Globe and Winkelman. That route will add about 20 miles to the trip.

As with any work zone, drivers are asked to drive slowly and cautiously in the work area and watch for construction workers and equipment.

Out-of-State travelers should be aware that Arizona Revised Statute 28-710 §B. provides for double fines for speeding through a marked highway work zone.
