State Route 840 is a state highway built around Nashville, Tennessee and managed by the Tennessee Department of Transportation (TDOT). First proposed by former Governor Lamar Alexander as part of a system of "Bicentennial Parkways", construction began in 1991 on the first segment extending south from Interstate 40 at Lebanon. The roadway currently serves the cities of Lebanon, Murfreesboro and Franklin. The nearly completed southern section is approximately 78 mi (125.5 km) long and was scheduled for completion in 2006; however, some construction remains between U.S. Route 31 near Franklin and Interstate 40 near Dickson.

Plans to extend SR 840 north past Dickson and past the cities of Clarksville, Springfield and Gallatin were put on hold as the Tennessee General Assembly recommended that TDOT discontinue further study amid concerns of social and economic problems. The entire loop was to be 178 mi (286.5 km) long. Other objections raised included the hilly nature of the terrain north of Nashville, which when compared to the existing southern route, would require more cutting, filling and bridge construction, resulting in higher construction costs per mile (in constant dollars) than that required for the southern route. In October 2003, TDOT placed the northern loop project on indefinite hold, citing a lack of documented transportation need and participation from local planners.^[1]

While initially referred to as "Interstate 840" or "I-840" by the media, all current official material refers to the road as a "State Route"; it is constructed entirely with state transportation funds and is not part of the Interstate Highway System. Critics of the project charge that this is due to the state's desire to avoid stricter federal environmental standards, particularly with regards to environmental impact statements, though nothing has been proven to date.
