Pima County officials announced the opening of the Mt. Lemmon Highway Friday afternoon after early morning whiteout conditions and heavy snow led to its closure just after 7 a.m. Friday.
However, the Pima County Sheriff's Department tweeted that the road is only open to residents. Chains and four-wheel drive are required to go up the highway, both the Pima County Department of Transportation and Sheriff's Department said.
The Transportation Department announced the closure of Wentworth Road at Tanque Verde Creek and Tanque Verde Loop Road at the Tanque Verde Creek.
For up-to-date road conditions, including closures, call the Sheriff's department road hotline at 547-7510.
