Norris Lake, formed by the Norris Dam impoundment of the Clinch River, wraps around much of the county’s northern and eastern edge and accounts for most of its 24 square miles of water. Big Ridge State Park sits on the lake’s southern shore. The county borders Claiborne County<\/a> to the north, Grainger County<\/a> to the east, Knox County<\/a> to the south, Anderson County<\/a> to the southwest, and Campbell County<\/a> to the northwest.<\/p>\n Union County recorded 19,802 residents at the 2020 census, an average density of about 88 people per square mile. Maynardville and Plainview are the two largest communities, together accounting for roughly a fifth of the county’s population. Median household income runs below the Tennessee median of $67,631, consistent with the county’s rural, mostly non-metro economic base despite its proximity to Knoxville.<\/p>\n Union County’s economy centers on retail and services along the Highway 33 corridor into Knoxville, small-scale farming, and lake-driven tourism around Norris Lake, where marinas and vacation rentals draw seasonal visitors. Many residents commute to Knoxville and Oak Ridge for work. Big Ridge State Park hosts hiking, camping, and swimming and is a local economic anchor in summer.<\/p>\n Union County was organized on January 23, 1856, carved from parts of five neighboring counties — Anderson, Campbell, Claiborne, Grainger, and Knox. Its name is traditionally explained one of two ways: as a reference to the “union” of territory drawn from those five counties, or as a nod to East Tennessee’s strong pro-Union sentiment on the eve of the Civil War. The original town of Loyston was relocated and largely submerged in the 1930s when the Tennessee Valley Authority built Norris Dam and flooded the Clinch River valley to create Norris Lake.<\/p>\n State Route 33 is the county’s main north-south corridor, connecting Maynardville to Knoxville. State Route 61 runs east-west through the northern part of the county toward Sharps Chapel and Norris Lake.<\/p>\n McGhee Tyson Airport in Alcoa, near Knoxville, is the nearest commercial airport.<\/p>\n Where is Union County, Tennessee?<\/strong> What is the population of Union County?<\/strong> How big is Union County?<\/strong> What is the county seat of Union County?<\/strong> How many towns are in Union County?<\/strong> |
