MIDDLEBURG | The 2-lane bridge over the creek’s South Prong is a closely traveled main thoroughfare via the county particularly for Middleburg, Lake Asbury and southern Clay County residents. Faculty buses serving eleven Clay County faculties usually use that route as nicely.
Storm surge fueled by heavy rains spawned by Hurricane Irma brought about structural injury to the bridge.
The county closed the bridge Sept. 19 as a security precaution when Florida Division of Transportation divers inspecting the construction found erosion — generally known as scouring — across the bridge base and help columns posing “a possible security difficulty.”
Bridge scour occurs when quick-shifting water rips sediment similar to sand or gravel away from the bridge abutments or basis. It will probably can scoop out scour holes threatening the integrity of the construction. Engineers say the most typical explanation for bridge failures is from floods scouring the mattress materials.
