Speed limits are falling along with the snow on the state’s largest two toll roads and icing is reported on state highways as Monday’s snow storm moves in a northwestern direction, dumping an inch an hour in some places.

Speeds have been dropped to 45 mph on three sections of the New Jersey Turnpike to allow salt and plow crews to work. They are from Interchange 6 -Pennsylvania Turnpike to the George Washington Bridge, on the Pennsylvania Turnpike Extension between the Delaware River Bridge to the Turnpike main line in Mansfield and on the Hudson County extension between I-78 and the Holland Tunnel, according to 511NJ alerts.

Garden State Parkway officials also advised drivers to reduce speed for salting and plowing between Exit 90 in Brick and the New York State line, but didn’t set a maximum speed.

The National Weather Service said the storm is moving in a north, northwesterly direction and dumping snow at a rate of 1 inch and hour. That is affecting I-287 between Edison and Bloomingdale, I-80 from the Delaware River to Totowa, I-78 from Clinton Township to Watchung, the weather service said.

NJDOT Traffic alerts also warn of icing on highways in the north and northwest, particularly on Route 10 in Denville, Route 19, between Clifton and Paterson, Route 23 between High Point and the New York State line and Route 24 in Morris Township.
