Pinal County is advising drivers they may find delays on roads for several months as crews repair sinkholes in Copper Basin, Rancho Bella Vista and Circle Cross Ranch. Workers will first remove failed material and re-compact the base, allowing it to stand for a few weeks before paving.
Some trenches may be left open overnight if the area needs to be dried out. The county plans to repair the worst areas first.
During the work, drivers may experience loose gravel on the road.
