Kyrock was a small town in Edmonson County in south central Kentucky. The town was located just east of Sweeden, or about north-northeast of the county seat of Brownsville. It was once a referred to as a “company town” along the Nolin River during much of the first half of the 20th century, but the industrial town no longer exists. It was disincorporated in 1957 after the closure of the company that operated it. Kyrock was one of several other central Edmonson County communities located near Mammoth Cave National Park.
History
Kentucky Rock Asphalt Company
In 1918, the town was incorporated into a town that was built by the Kentucky Rock Asphalt Company, which the town's name, Kyrock, is derived from. During the company's heyday in the 1920s, the company mined, processed, and shipped hundreds of tons of rock asphalt, by way of both the Nolin and Green Rivers. This was done to eventually pave roadways in areas where they were not previously served by minor or major roadways at the time. The company itself began operations in 1917 after a merger between two companies involved in rock mining and paving. Eight new quarries and a processing facility, which ended up becoming a vital part of the county's history, opened at the site that would become part of the town, which was incorporated in 1918. The material generated by the company, made of silica sand, was the first material ever laid for the Indianapolis Motor Speedway. The asphalt rock from Kyrock was also used to pave the streets of major cities such as Rio de Janeiro, Brazil, and Havana, Cuba. The company stayed open for a total of forty years with its heavy promotions and advertising, becoming the state's most successful asphalt mine during that period. Higher costs to pave with asphalt resulted in the end of the company since petroleum-based asphalt was a lower-cost method of paving. The Kentucky Rock Asphalt Company was shut down in 1957. The town itself was unincorporated at some point in the late 1950s. Kyrock's post office operated from 1920 to 1955.
In addition to the Nolin River, Kyrock was also served with a ferry that connected the town to Whistle Mountain, and eventually to areas along what is now KY 728 into the northeastern portion of the county. Ferry service was discontinued a few years before the U.S. Army Corps of Engineers impounded Nolin River to build Nolin Dam in 1963. Today, Kyrock is nothing more than an unincorporated community along a county-maintained road off State Highway 259 near Sweeden. Kyrock Road is accessible from both KY 259 from Brownsville and KY 728 from the Nolin Lake area.
