A call to Putnam County 911 Dispatch Thursday afternoon alerted authorities to damage to the southeast end of Dunbar Covered Bridge in Greencastle Township. The call came in at 2:57 p.m., with Putnam County Sheriff's Department Lt. Donnie Pettit responding to investigate and a Putnam County Highway Department unit (pictured) later reporting to assess the damage. There is no major structural problem, with the impact only knocking loose a cross member support and several pieces of wooden siding. The 135-year-old bridge over Big Walnut Creek has been damaged several times in the last few years, with the culprits on at least two occasions being semi drivers whose GPS units led them on an unfortunate route through the Putnam County countryside. No word was available on the cause of the damage as of Thursday evening.
