Northbound Interstate 680 in Pleasanton has reopened after an hourslong closure caused by a large truck that hit an overhead sign early Wednesday morning, according to the California Highway Patrol.
The truck, which was part of an overnight paving operation on the highway, struck the overhead sign around 3:50 a.m. south of the interchange with Interstate 580 and eventually prompted the full closure of the northbound lanes so the sign could be inspected, CHP officials said.
Caltrans officials eventually determined the sign had to be removed for safety reasons, extending the delay. The highway eventually reopened by about 11:20 a.m., according to the CHP, which was diverting northbound drivers off the highway to Stoneridge Drive during the closure.
