Lancaster police said a parking ban on snow emergency routes is still in effect, even though most main streets have been plowed.
Police said crews will continue to plow emergency routes throughout the night and into tomorrow as needed.
Authorities are concerned that people may assume it is okay to move their vehicles back onto the snow emergency routes because the plows have been through.
More cleanup work remains, however, and more snowfall is anticipated.
People should not park on snow emergency routes until the snow emergency has been lifted.
