SPARTA, KY (FOX19) - One hundred laps into the inaugural Quaker State 400 at the Kentucky Speedway thousands of race fans sat in their cars, missing the race.
Traffic was a nightmare for fans and the speedway.
This year, they've made changes, hoping to alleviate some of the traffic backup.
"Our team is committed to getting this thing right and we will," Mark Simendinger, General Manager of the Kentucky Speedway said.
Thursday the Kentucky State Police released its traffic plan for race day, June 30th.
The Kentucky Speedway widened Kentucky Highway 35 to five lanes and on race day can expand to seven if needed.
There are 20,000 new parking spaces for cars and fans can use the pedestrian tunnel to improve traffic flow. This year barrels will tell drivers where to go on Highway 35 instead of troopers to avoid backups. Kentucky State Police will be reserved for pedestrian, vehicle conflicts and parking assistance.
The exit ramp from Interstate 71 South to Kentucky 35 now has an extra third lane.
Kentucky State Police say drivers headed south from the Cincinnati area will need to take I-71 South to Exit 57 to reach the racetrack.
"When we were doing all the planning and trying to figure out what went wrong, I was more concerned then," Simendinger said. "I'm not concerned now. Now I now that we've got it in place, now I'm just eager to show it off."
Kentucky State Police say they will be tweeting traffic updates on the half hour throughout race day. They also recommend drivers tune in to AM 1620 for traffic information.
Police say they are hoping to divert commercial traffic off I-71 by instead directing them to I-75 and I-64.
Wreckers will also be pre-positioned on the interstate and near the track for stalled vehicles or collisions.
Following the race, traffic will be delayed by 30 minutes to allow pedestrians to safely leave the event. The infield will remain unmoved for 90 minutes.
