Hello, Im interested in acquiring just the smaller section towards the end of this bridge. Is that possible? Thanx.

This bridge is located 3.5 miles west of Chelsea. A few years ago someone tried to start a fire on the bridge planking. Local fire dept. put out the fire and it now has a steel plate covering the small burned hole.
