According to the Federal Highway Administration (FHWA) National Bridge Inventory, counties own and maintain 5,051 bridges – 35% of the nearly 15,000 bridges in Kentucky.
Federal regulations define a bridge as a structure at least 20 feet long that carries traffic over a depression or obstruction. Counties own and maintain many smaller structures that may look like a bridge, but do not meet the federal criteria and definition to be included in the National Bridge Inventory.
County-by-County
The number of county-owned bridges varies by county, ranging from just four up to 183 bridges. The median number of bridges that Kentucky counties own and maintain is 37.
Six counties own more than 100 bridges: Jefferson (183), Graves (125), Pike (118), Christian (114), Harlan (105) and Daviess (104). Only three counties own fewer than 10 bridges: Meade (4), Edmonson (9) and Gallatin (9).
