SEVIERVILLE, Tenn. (WVLT) -- The Tennessee Department of Transportation is giving people in Sevier County a look at a proposed change to the 407 interchange Thursday evening.
TDOT proposes building a diverging diamond interchange, a design spokesperson Mark Nagi says would be safer and help keep traffic flowing easier on and off the interstate.
"This is something that isn't seen a lot," said Nagi. "But I think the folks who've seen the diverging diamond interchange in Alcoa, it's something that was put in there a couple of years ago, they're used to it."
A public hearing Thursday gave people a chance to see what the interchange would look like. TDOT estimates that over the next 20 years, traffic through the interchange will approach 180,000 cars per day.
"The public that's trying to get to Sevierville, Pigeon Forge, Gatlinburg, this is something they've been anticipating and it's something that certainly will be welcome," Nagi added.
TDOT says they hope to get a bid out for construction by the end of the year, it would take 12 to 18 months for construction to be finished.
