Caltrans said that beginning in early August, a portion of Union Road will be closed for around two months. Video in the media player above from past coverage. The section of Union Road between San Juan Hollister Road and Highway 156 will be closed for eight weeks or less. The exact days for the closure will be announced within a week of the closure, said Caltrans.This closure is needed to rebuild the intersection of Union Road and Highway 156, to help with the Highway 156 widening project, and to improve access to and from the highway.During construction, there will be a detour through San Juan Hollister Road to get to Highway 156. "Following the anticipated reopening of Union Road in late summer, two exciting milestones will be met, as traffic on SR 156 will be shifted onto the new paving just south of the existing highway and a new roundabout will be in operation at Bixby Road," Caltrans said in a media release. Additional traffic control devices will be installed at Fourth Street and Highway 156, San Juan Hollister Road and Fourth Street/Business 156. There will also be a temporary closure of Mitchell Road, just north of Highway 156 after Union Road is reopened.
