A discovery by a CalTrans worker on the side of the road near Kirkwood resort resulted in a call to the Calaveras County Bomb Squad. According to Craig Harmon, the CHP’s Public Information Officer, the worker reported finding a device that may have been a functional pipe bomb late Tuesday morning. The Calaveras Bomb Squad, based in San Andreas, shut down Highway 88 in both directions for approximately 2 hours and 40 minutes. The Bomb Squad used additional explosives to detonate the device. The Amador and Calaveras County Sheriff Departments are investigating the supposed bomb and how it got there.
