LOUISVILLE, Ky. (WHAS11) – The widening of Interstate 65 in Southern Indiana is expected wrap up later this week after two long years of construction.

The $67 million project aimed to improve safety and traffic flow by creating three lanes of traffic in each direction.

As the project nears completion, the northbound lanes of I-65 are still being diverted to the west side of the highway from the 8 to 11-mile markers. An Indiana Department of Transportation spokesperson said the three-mile stretch of roadway would start to transform overnight Wednesday when crews are expected to reroute northbound traffic back to the east side of the highway.

Later in the week, after crews install a median guardrail, all six lanes of traffic will open from mile marker 8 near Sellersburg to mile marker 16.6 just north of Memphis Road.

Many Southern Indiana drivers said the project’s completion would be a welcome change. The worksite has become notorious for traffic headaches and slowdowns.

“I’ll be so glad when it’s finished. I wonder why is there always something going on and it never seems like it gets accomplished,” Sellersburg resident Linda Long said. “I’m like, when are we ever gonna be able to just drive on these roads and enjoy a smooth sail?”

INDOT said the project’s completion would be the end of most construction in the area until spring.

Crews are expected to return in May or June to pave the same section of I-65 with a type of premium asphalt that can only be laid during warmer weather.
