Roadway Weather Implementation System


Scope of Work

Scope of  Work

The Connecticut Department of Transportation currently has thirteen (13) Roadway Weather Information System (RWIS) sites.

    The RWIS sites provide real-time weather information to the Department which is used to manage winter maintenance and weather related activities.  The Department is developing plans for installation of twenty-five (25)  additional sites which will expand the geographic coverage of the RWIS and offer improved responses by the Department maintenance crews to provide safe roadway conditions.  RWIS sites will include a fenced-in tower and an illumination pole close to the roadway that holds atmospheric sensors and road pavement sensors.
