State Route 840 will soon be designated as an interstate following a Federal Highway Administration ruling.

Interstates allow drivers to travel faster and avoid congestion, according to a release from the Tennessee Department of Transportation.

The FHA approved a request to change the road's designation.

TDOT has not said whether the speed limit will be raised following the change.

The change should be complete by the end of 2016 and will cost TDOT $230,000 to change signs.

TDOT reports the change was requested to encourage more economic growth along the corridor and more traffic diversion around Middle Tennessee's urban core.
