A Danbury woman has been arrested for a wrong way crash that happened on I-84 in Newtown yesterday morning.  41-year old Crystal Smith was charged with Operating Under the Influence, Driving the Wrong Way, and Reckless Endangerment.  Troopers responded to the eastbound side of the highway shortly after 2am on a report of a car headed westbound.  The vehicle collided with  a tractor trailer head-on.  The truck then went off the roadway, damaging about 100 feet of the wire rope guardrail  Smith refused to complete field sobriety tests and was taken into custody.  She sustained minor injuries and was released on bond for a court appearance on the 15th.  The accident closed the eastbound side of the highway into the morning commute.
