A driver was injured Sunday in Newtown when their van went off the roadway in the icy conditions.  Firefighters responded to Lakeview Terrace, where the driver reported chest and arm pain.  The full-size van had crossed the roadway and gone down an embankment. The vehicle landed about 10 feet off the roadway.  The driver was checked, and then transported to a hospital.  Traffic was temporarily reduced to alternating lanes while first responders were on the scene due to the narrow, winding roadway.
