YOSEMITE – Visitors to Yosemite National Park should be prepared for one-lane traffic control at numerous locations throughout the park through the end of October.
From Sept. 10 to Oct. 28, 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 underground conduit/ wiring along the shoulder of the road and installing an Automatic Traffic Data Recorder.
While work is underway, visitors should expect to see a flagging operation that will reduce traffic to one lane for approximately three 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.
Motorists should expect day work along Tioga Road, Big Oak Flat Road, Wawona and Glacier Point Roads, Southside Drive near the Chapel, and along 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 conducted on the weekends, from Friday night to Sunday afternoon.
