MoDOT is starting construction on Interstate 64 east of Kingshighway.
Three lanes of traffic will be open both east and westbound during the weekdays, but traffic will go down to one lane each way overnight.
MoDOT area engineer Deanna Venker says this is really the second phase of the new I-64 project.
“Just east of Kingshighway all the way down to Boyle was the last section of I-64 that didn't get done,” Venker said. “And you do have four bridges that need to be replaced, as well as an interchange.”
