● Route Description

The route of I-26 begins in Columbia, South Carolina, at an intersection with Interstate 126 and US Route 76, near the South Carolina State House and the University of South Carolina. From there, it heads northwest, passing through the Lexington County and Newberry County, before entering North Carolina and continuing through the Polk County and Henderson County. I-26 then intersects with Interstate 40 and US Route 25 near Asheville, North Carolina, close to the Biltmore Estate and the Blue Ridge Parkway. The highway also passes near the Great Smoky Mountains National Park, which is managed by the National Park Service and is home to a diverse range of flora and fauna, including black bears, white-tailed deer, and turkeys.

● History

The construction of I-26 began in the 1960s, as part of the Federal Aid Highway Act of 1956, which was signed into law by President Dwight D. Eisenhower and aimed to improve the nation's highway system. The highway was designed to provide a direct route between the Port of Charleston and the Tennessee Valley Authority, and to facilitate the transportation of goods and people through the region. I-26 was officially completed in 1969, with a ceremony attended by Governor Robert Evander McNair of South Carolina and Governor Robert W. Scott of North Carolina. The highway has since undergone several improvements and expansions, including the construction of new interchanges and the widening of existing lanes, with the help of organizations like the Federal Highway Administration and the American Association of State Highway and Transportation Officials.

● Major Interchanges

I-26 has several major interchanges with other highways, including Interstate 77 near Columbia, South Carolina, Interstate 85 near Spartanburg, South Carolina, and Interstate 40 near Asheville, North Carolina. The highway also intersects with US Route 25 and US Route 74 near Hendersonville, North Carolina, and with US Route 23 and US Route 321 near Johnson City, Tennessee. These interchanges provide access to nearby cities and attractions, such as the Riverbanks Zoo and Garden in Columbia, South Carolina, the Biltmore Estate in Asheville, North Carolina, and the Tennessee Theatre in Knoxville, Tennessee, which is listed on the National Register of Historic Places.

● Traffic Volume

The traffic volume on I-26 varies depending on the location and time of day, with the highest volumes typically occurring near major interchanges and urban areas. According to data from the Federal Highway Administration, the average annual daily traffic volume on I-26 ranges from around 20,000 vehicles per day in rural areas to over 100,000 vehicles per day near Columbia, South Carolina and Asheville, North Carolina. The highway is also an important route for commercial traffic, with many trucking companies and logistics providers using I-26 to transport goods through the region, including FedEx, UPS, and CSX Transportation.

Interstate 126 is a spur route that connects I-26 to the Port of Charleston, while Interstate 526 is a bypass route that provides access to the Charleston International Airport and the Medical University of South Carolina. Other auxiliary routes, such as US Route 176 and US Route 221, provide access to smaller towns and rural areas along the route, including Newberry, South Carolina and Spartanburg, South Carolina, which are home to institutions like Newberry College and Wofford College.
