Sensors making roads safer in winter weather

With the first signs of winter in the air, the Metropolitan Transportation Authority will be relying on weather sensors on New York City bridges.

The high-tech devices, which can be seen on all local bridges, including the Whitestone Bridge in the Bronx, give the MTA up-to-the-minute information on winds speeds, rain and snow levels.

If conditions on the roads become hazardous, the MTA can quickly make adjustments, lowering the speed limit, banning certain vehicles or dispatching de-icing trucks.

The weather sensors were installed in the 1990s, but they were upgraded last winter to report conditions in real time.
