Colorado is testing out using a helium-filled blimp to monitor traffic on roadways.
The Colorado Department of Transportation is set to launch the blimp over Interstate 25 Tuesday afternoon and try it out for three days. The blimp, which will be tethered to the ground, will be flown up to 400 feet above I-25 near Interstate 76 and U.S. Highway 36.
CDOT says several other cities and transportation departments have also been considering using blimps for traffic monitoring.
It will be testing out how the blimp can operate with its various highway cameras and fiber optic network.
