"The project that's currently under construction is from the Natcher Parkway down to the Dillard-McClellan Intersection. And what we are doing is widening from two lanes to five lanes," says Keirsten Jaggers with the KY Transportation Cabinet.
Nashville Rd. will also have a center turning lane.
Businesses in the area say the construction is helping.
"The transition has gone really well. They've made it where we can have an entrance and an exit at all times," says Larry Hill with Green River Rentals.
"I've been with the company a year and a half and since I've been here the traffic has just been horrendous," Melinda Sears with Weed Man Lawn Care says, "I will look out this window, and from Elrod Rd., it's a pretty good distance, it's backed up past the office here."
And some businesses are saying it's long overdue.
"I'm very glad to see it finally happening, something in my opinion that should have been done probably ten years ago. This road is just much much too busy to be left as a two-lane all these many years," Sears says.
And the Tansportation Cabinet expects the construction to fix that problem.
"It's a busy roadway and it needs to be widened so that it can carry the volume of traffic that it has on a daily basis," Jaggers says.
The project between the Natcher and Dillard Road will be done by spring 2013.
"We're looking at, widening long-term, the entire length of 31-W down to the state line. As most people know when we have an accident that's where we flip most traffic over to is 31-W," Jaggers says.
Once the current project is complete, the Transportation Cabinet will start widening the road at the Dillard-McClellan Intersection to Richpond-Rockfield Rd.
