From September 10 to October 28, 2018 the park will be replacing the existing traffic counters in Yosemite, beginning this week along Tioga Road. At each location, the park will be installing loop vehicle detectors in each lane, trenching and placing undergroud conduit/wiring along the shoulder of the road and installing an Automatic Traffic Data Recorder.
While work is under way, you should expect to see a flagging operation that will reduce traffic to one lane. Each lane will be closed for approximately 3 hours. A flagger and traffic cones will be out in the work zones. This may cause short traffic delays during the day as work crews proceed with digging and cutting operations along the shoulder of the road and in the roadway. Motorsits should expect day work along Tioga Road, Big Oak Flat Road, Wawona and Glacier Point Roads, Southside Drive near the Chapel, and Northside Drive near Camp 4. Night work will take place at the South Entrance, Arch Rock, and Big Oak Flat Entrance. Work will not be conduted on the weekends, from Friday night to Sunday afternoon.
