When police couldn’t stop a fleeing burglary suspect on Interstate 70 last week, a fleet of snowplow drivers stepped in to help. Colorado Department of Transportation snowplows traveling up Floyd Hill on I-70 ahead of the car chase began to slow down and block the highway’s lanes, trapping the suspect, the Idaho Springs Police Department said in a Friday statement on Facebook. “We’re at a roadblock with three plows, they’ve got I-70 shut down,” one officer can be heard saying in a video posted by the police department. The blockade forced the fleeing driver to stop and turn himself over to police, investigators said. Around 11:30 p.m.
