A semi gets wedged under the viaduct on South Clinton Street in Defiance. No one is hurt in the crash, officials say. The driver was northbound when the top of the cab and trailer hit the top of the CSX Railroad span, which has a clearance of 11 feet, nine inches. The collision partially dislodged the sign noting the structure’s clearance. The top of the truck cab is heavily damaged along with the front part of the trailer. It takes some time to get the wreckage out of there. When they do…then inspect the viaduct for damage…they sound the all clear…and traffic moves again.
