The section of state Route 364 between Grand Lake St. Marys State Park entrance and Koenig Road was blocked off for a while Sunday following an auto accident resulting in a natural gas leak. Elizabeth L. Humphrey, 63, 315 Parkway Drive, St. Marys, was westbound at 12:30 p.m. when she attempted a left turn and her vehicle struck the eastbound vehicle of Brian D. Brosher, 37, 7300 state Route 197, Celina. The Brosher vehicle traveled off the right side of the road and struck a gas meter. Both Brosher's 2004 Ford Taurus and Humphrey's 1994 Oldsmobile Cutlass received moderate damage. Humphrey was cited for failure to yield the right of way when turning left.
