The 43-mile-long highway to the North Rim of the Grand Canyon closes Thursday for the winter.
The Arizona Department of Transportation says State Route 67 will be closed about a half-mile south of its junction with US 89A at Jacob Lake.
Most visitor facilities on the North Rim are already closed for the winter.
The highway is scheduled to reopen in mid-May along with North Rim lodges, campgrounds and other amenities.
The South Rim remains open all year.
