Department of Transportation


The New Jersey Department of Transportation (NJDOT) is prepared to clear snow and ice from roadways statewide. NJDOT fills its salt and liquid calcium inventories, fits its trucks with plows and is ready to deploy personnel to ensure motorist safety during the winter season.

NJDOT maintains 41 remote roadway weather sensing stations (RWIS) to help keep crews informed of road conditions on the state highway system. These stations provide detailed information on weather and road conditions in specific regions of the state, including air temperature, humidity, wind speed and direction and road and bridge surface temperatures.

The following information illustrates the scope of facilities and material necessary to successfully combat winter weather on the 13,341 lane-miles of highways in New Jersey.
