Construction Continues Along I-77

The project extends along Interstate-77 from the Interstate-20 exits to Killian Road and costs about $90 million.

Richland County, SC (WLTX) - You can't miss it. There's a lot of work going on along I-77 from the I-20 exits all the way to Killian Road and even into Blythewood.

"Interstate-77 is a widening project that we started a couple of years ago," Allen Thompson said.

Thompson is an Assistant District Construction Engineer for the South Carolina Department of Transportation. Thompson said construction for this project began in 2016, but planning is extensive and has been going on for even longer.

"You have environmental [studies]. You have traffic studies. You do some preliminary engineering on your layers of asphalt that exist and are currently there, so there's quite a bit of work that goes into planning a project like this," he said.

By widening the road, crews are able to add an additional lane in both the northbound and southbound directions.

"The main concern is easing traffic. There will be some safety improvements," Thompson said.

This project will cost about $90 million and is expected to be complete in the fall of this year.

"It's good to get his finished for the public and allow them to start using it for its full benefit," he said.

During your commute, you will also see construction for a bridge replacement along 277 NB and bridge maintenance at both Killian Road and Blythewood Road.
