But police still urge drivers to use "extreme caution," a police spokesman said.

The news release indicated that about 100 officers from Highway Patrol, the sixth and seventh precincts, emergency services, K-9 officers and officers from the Riverhead Town police and parks police assisted in closing and reopening the roads while they were being sanded.

"Drivers are still advised to remain off the roads," police said in a statement, adding that there is still ice on many roadways.

"Please use extreme caution if driving tonight," police said.
