Kentucky Route 212 (KY 212) is a short state highway located in Boone County, in the northern region of the U.S. state of Kentucky. The highway is approximately 1.3 miles (2.1 km) long, and partially constructed as a freeway, with the rest being a divided highway. The roadway links Interstate 275 (I-275) to the Cincinnati/Northern Kentucky International Airport (CVG Airport), and has been designated as a connector route by the Federal Highway Administration (FHWA). A road first appeared near the location of KY 212 around 1937. A short road was built in the location of KY 212 when the U.S. Army Air Corps built the predecessor to the CVG Airport. The road was reconstructed to a divided highway in 1972, and has remained relatively unchanged since.

Route description[edit]

Kentucky Route 212 begins at an incomplete interchange with a one-way loop road, named Terminal Drive, in the central region of Cincinnati/Northern Kentucky International Airport. At this interchange, KY 212 is a four-lane divided highway. The highway proceeds northeast reaching a diamond interchange with Kentucky Route 236 (Donaldson Road). A turnaround ramp that transfers southbound traffic to the northbound lanes is located a short distance from the termini of the southbound ramps of the interchange. The roadway continues northward from the interchange, passing a large airport parking lot and a small airport road before reaching an incomplete A4 partial cloverleaf interchange with I-275. The interchange is lacking a ramp connecting I-275 eastbound with KY 212's northbound lanes. The road proceeds northward from the interchange, passing a few small businesses before reaching its northern terminus, an at-grade intersection with Kentucky Route 20, known as Petersburg Road.[3][4]

Kentucky Route 212 is maintained by the Kentucky Transportation Cabinet (KYTC). Part of the job of the KYTC is to measure traffic along the highway. These counts are taken using a metric called annual average daily traffic (AADT). This is a statistical calculation of the average daily number of vehicles that travel along a portion of the highway. The highest AADT along KY 212 at the southern portion of the interchange with I-275, with an approximate count of 21,219 vehicles. The lowest AADT along the highway is just north of the interchange with I-275, with an approximate count of 11,100 vehicles.[5] The portion of the highway traveling from the interchange with I-275 to the southern terminus is designated as an Intermodal Connector Route,[6] part of the National Highway System, a network of roads important to the country's economy, defense, and mobility.[7]
