CSX freight train passing underneath wooden bridge

Although the train was a short one, this bridge vibrated quite a bit when the engines roared underneath

Description 

According to neighbors, the original timber bridge here was destroyed when a southbound freight train crashed into it 13 years ago, leaving a gaping hole in the center and intact timbers on either side. It was replaced after maintenance responsibility was decided between CSX and Anderson County.

I drive across this bridge frequently. I don't believe it's "closed to all traffic."
