Truckers who normally take Interstate 40 through downtown Knoxville, TN, will be detoured onto I-640 and I-275 for the next 14 months. Highway crews shut down a section of I-40 on Thursday, May 1.

The closure and reconstruction of a 0.9-mile section of I-40 will include widening the stretch to six lanes; adding four auxiliary lanes; and building nine overpasses, new ramps and noise barriers.

The $275 million project is due to be complete by July 1 next year.
