The Georgia State Patrol says that a thirty-year-old Calhoun man walked away without injury after his car left the roadway and overturned last Saturday on Penn Bridge Road one mile north of Alexander Road .  According to a report from the Georgia State Patrol Public Information Office, Hervin Ramirez-Aguilar lost control of the 2011 Nissan Maxima he was driving while attempting to navigate a curve on the wet roadway.  The front of the vehicle struck the guardrail and overturned, going down a slight embankment, not far from the Chattooga River.  Rameriz-Aguilar was cited for failure to maintain a single lane.
