Crews have begun work on a new construction project at the I-40 / I-240 flyover.
The project is scheduled to be completed in 2017.
That means major headaches in one of the area's busiest interchanges.
The $109 million undertaking will widen Sam Cooper by one lane each way.
I-240 from Walnut Grove to the interchange and from the interchange to Covington Pike will also be widened.
The portions of I-40 on the interchange will become two lanes.
Right now about 200,000 vehicles travel that interchange each day.
