Traveling 78 miles from I-40 near Dickson to I-40 at Lebanon, Tennessee 840 provides a long distance bypass of Nashville-Davidson County while serving suburban growth at Smyrna, Murfreesboro, Franklin and Spring Hill. Development of the beltway was approved by the state legislature as part of the Better Roads Program in 1986.1 Construction started in 1991.2

The first portion of SR 840 completed was the six-mile segment between Stewarts Ferry Pike (Exit 70) at Gladeville and Interstate 40 to the southwest of Lebanon. It opened in August 1995. Subsequent stretches followed from Exit 70 southwest to I-24 in November 1996, from I-24 west to U.S. 31A & 41A (Exit 42) in November 2000 and from there west to I-65 by October 2001.

Construction along the western third of SR 840 started on the beltway from I-40 to SR 100 (Exit 7). That portion opened in December 2002. Delays on further construction ensued as a Leipers Fork area citizens group opposed the route due to environmental concerns. This prompted a redesign of the route into a scenic highway.3 The initial extension opened east from SR 100 to SR 46 (Exit 14) in October 2010.1

Two separate projects involved building the final 12 miles between Bending Chestnut Road and U.S. 31 (Exit 28) at Thompson's Station. A ribbon cutting ceremony held just west of the Carters Creek Pike (SR 246) interchange (Exit 23) on November 2, 2012 celebrated the completion of SR 840. The 26-year project cost $756 million.2,3
