WALNUT CREEK -- AT&T had its wireless services restored by Friday morning after a cable cut from by a road construction contractor disabled services for East Bay customers for almost two days.

Technicians worked around the clock to repair the damage that occurred during work on a road project, and service is currently running normally, said Alex Carey, a company spokesman.

The cuts occurred during construction near the Dick's Sporting Goods store in Pleasant Hill, said Walnut Creek spokeswoman Gayle Vassar.

The cuts left some customers in the Walnut Creek area without services, Carey said.

Contra Costa Community College District's office in Martinez, John Muir Medical Center, some county clinics, the Safeway and Walgreens on Deer Valley Road in Antioch and businesses in downtown Pittsburg and Antioch also reported service disruptions. Some classes at Los Medanos College were not able to do Internet research and put a "kink in the operations," professor Curtis Corlew said.

"It shows that we're so used to having it," he said.

Those incidents are likely related, since there were no other issues in the area, Carey said.
