The popular Cades Cove Loop in the Great Smoky Mountains National Park will close for about a day and a half for bug treatment.
Rangers will close the road to all vehicular traffic on Monday, Dec. 3 and implement a partial closure on Tuesday, Dec. 4, a park spokesperson said.
Hikers will be allowed to enter the park on Dec. 3, but bicycles and all motor vehicles will be blocked.
The spraying work on Dec. 4 will only involve the western end of the loop, so motorists and cyclists will be able to enter the road, but will have to detour across the loop via Hyatt Lane.
During the closure, park forestry technicians will treat hemlock trees infested with the hemlock woolly adelgid. The crews use a horticultural oil sprayed from large truck-mounted units. The park has used the treatment since 2004.
The work will be rescheduled if there is heavy rain or freezing weather.
To check the status of the road closure, visitors can call the park's general information number at (865) 436-1200.
