The car, a 2010 Toyota Camry being driven by a 55-year-old woman, spun out and crashed into the median.

Officials say there is some minor damage to the car’s bumper.

The driver was not injured.

There were some traffic back-ups as the flag and car were removed from the bridge.

The flag was scheduled to come down this coming on Tuesday night during a scheduled lane closure on the bridge.

A new flag has been ordered. The state says it will be looking for a new type of rope or mounting to make sure there are no similar incidents in the future.
