The Tennessee Department of Transportation is trying to stop accidents and save lives after a year-long study of Interstate 24 it recently completed.
"Part of that study was identifying some sections of I-24 where the crash rate was kind of higher than the statewide average. So there are four spots here in Davidson County and one in Robertson County that we've identified," said TDOT spokeswoman Deanna Lambert.
Drivers who participated in the study also offered information on congestion, which figured in with the crash rate that was more than the state average of about one wreck for every million miles driven.
One trouble spot is near Coopertown at exit 24, where two narrow lanes easily get congested.
Another trouble spot is the I-24/I-65 split in Nashville.
"It can be really confusing when you are going down six or eight lanes of traffic and you get ready to split or merge," Lambert said.
TDOT crews have already started the improvement project at that split and on I-24 at Shelby Avenue by adding more signs to clearly mark which lanes are I-24.
"If people would pay attention to the signs before they get up on the signs, that'll help even greater," said driver Ernest Davis.
The goal of this project is to cut down on drivers' confusion, which can cause crashes and congestion, so TDOT officials says drivers shouldn't notice any construction, maybe just a few new signs that aim to help traffic roll along a whole lot smoother.
