NASHVILLE, Tenn. - It's a project that started in 1986 and still isn't finished.
When complete, State Route 840 South will link Dickson County to Williamson County and Williamson County to Wilson County, in a loop to the south of Nashville.
While most Middle Tennesseans have no idea, parts of the 840 project are starting to look less like piles of dirt and more like roads.
"We have two projects, over $130 million worth of construction going on in Williamson County right now," B.J. Doughty, spokespersons for the Department of Transportation, told News 2.
She said there are two sections of SR-840 currently under construction.
The Highways, Inc. project stretches from Highway 100 to Pinewood Road (SR-46) and consists of 10 bridges, four of which are split bridges.
All of the bridges have been constructed with the exception of one, at Deer Ridge Road.
The project is 6.1 miles long and will include the grading and drainage for the SR-840 roadway.
It is scheduled to be complete in December 2010.
In December 2009, TDOT will open bids on the remaining portions of SR-840, which will stretch from Pinewood Road (SR-46) to west of Leiper's Creek Road, completing the loop.
"There is light at the end of the tunnel for us," Doughty said. "There are people who have been working on this project their entire careers in some form or stage of the project, whether design or getting to construction point."
The SR-840 project was delayed for five years while environmental issues were hashed out in court.
TDOT hopes to open SR-840 to traffic in December 2012.
"I think [there are] going to be a lot motorists, not just in the Middle Tennessee area, but people who are traveling from out of state or other ends of the state that will be excited to have this loop open and divert away from Nashville," said Doughty.
When finished, the 78-mile project will connect Interstate 40 West near Dickson to Interstate 40 near Lebanon.
