The section of US 27 currently under construction goes from the Tennessee River to Signal Mountain Boulevard. This section was first constructed by the department in the 1920s and completed on April 27, 1928.
US 27 is a north-south highway begins at Fort Wayne, Indiana and ends in Miami, Florida. The Chattanooga segment first appeared as the Dixie Highway in the 1910s as a direct route between Michigan and Florida.
In the Chattanooga area, the route is referred to as Corridor J, a designation of the Appalachian Development Highway System. In Tennessee, US 27 begins at I-24 and regionally goes through Soddy-Daisy, Dayton, Rockwood, Harriman, Wartburg, Oneida and on to the Kentucky border.
Ironically, the Dixie Highway, the predecessor to portions of US 27, had its beginnings in Chattanooga. In 1914, Indianapolis businessman Carl Fisher met in Chattanooga with other likeminded businessmen who believed a route to promote development from the Midwest to the South was needed. It was constructed and expanded from beginning in 1915 to 1927 when the federal government began to provide increasing funding for highways across our nation.
