It happened in the southeast near the turnoff for Anderson Road and Bow Bottom Trail at around 9:30 p.m.

In a news release, police said the driver was travelling in the exit lanes when he attempted to get back on the through lanes by crossing over a snow-covered divider.

“The Pontiac struck a sign on the median between the exit lanes and the through lanes and left the road to the right, travelling through the ditch. The Pontiac then struck the base of a lamp post causing severe damage to the front driver side of the vehicle.”
