MTA Bridges and Tunnels will use its fleet of 100 snow-fighting trucks and other pieces of heavy equipment. In addition, MTA Bridges and Tunnels uses weather sensors that deliver highly-accurate weather information, including wind velocity, wind direction, humidity and precipitation, via wireless communication. Other sensors are embedded in the roadway and on the snow-fighting trucks to monitor icing conditions on the roadways.
Bridges and Tunnels personnel will institute the following procedures during specific winter weather conditions:
• During light snowfall of less than 3 inches, motorists will be asked to operate at reduced speeds;
• Under heavy or severe snow conditions where accumulations of snow or a combination of mixed snow and ice are above 3 inches, some roadway lanes or ramp closures may occur while snow removal and de-icing operations are performed. Motorists will be asked to operate at reduced speeds;
• In blizzard conditions, which may include dangerous whiteout conditions combining snow, high winds and/or ice, bridges, tunnels and entrance and exit ramps at all MTA crossings may be subject to closure for the safety of motorists and employees.
