Private contractors will have 24 hours to clear residential streets, beginning at 6 a.m. on Saturday.
Crews will clear at least a 10-foot path to allow vehicles to pass.

Detroit DPW crews have been plowing and salting the city's 673 miles of major roads since 2 a.m. Friday, and will be working around the clock until major roads are cleared.
