Murphys, CA…CalTrans is installing the two-way center turn lane on Highway 4 in Murphys from Pennsylvania Gulch Road to Lawrence Street. The project is expected to begin this June and work complete in the fall. Most of the work will be done at night with one-way traffic control. The full two lanes of Highway4 should be open during normal daylight hours. As CalTrans gets closer to the start, more information will be available.
