JEFFERSON CITY — Even Missouri roads are getting high-tech with weather sensors placed along Interstate 44.

The Missouri Department of Transportation says 14 sensors placed on the highway provide information like pavement temperature and wind direction. The department uses the data to decide how to treat road surfaces during harsh weather.

The sensors cost $451,000 and were installed by December along I-44 from the Oklahoma border to the St. Louis area.

MoDOT says the devices saved thousands of dollars during winter storms because road crews knew which sections of highway needed to be cleared or treated with chemicals.
