Bell & Associates is currently working on the latest 840 project in Williamson County, just south of Nashville. This phase of the 840 project spans from west of Leipers Creek Road to west of Columbia Pike, State Route 6. This 7.9 mile section was awarded in December 2008 to Bell and includes grading, drainage, and construction of bridges and retaining walls. The estimated completion date of this section of 840 is December 31, 2011.
State Route 840 was initiated in 1986 as part of the state's Better Roads Program to provide economic growth by improving access to communities in Middle Tennessee. On the 78-mile route, 57.1 miles are open to traffic, with 20.9 miles remaining in some phase of construction or development. The entire route is scheduled to be open to traffic by 2012.When the entire route is complete, State Route 840 will connect to Interstate 40 near Lebanon (East of downtown Nashville) and near Dickson (West of downtown Nashville).
