A new interchange at Interstate 435 and Antioch Road in Johnson County is on track to open to all traffic by late Monday afternoon.

The new interchange is scheduled to be “completely” ready for all traffic, using all ramps to and from the interstate and all turn lanes onto the interstate from Antioch, said Kim Qualls, a spokeswoman for the Kansas Department of Transportation.

All that, of course, is weather permitting, she said.

The interchange is part of a four-year, $127 million project to upgrade U.S. Highway 69, I-435 and Antioch in Johnson County. The overall project is scheduled to be finished by late December.
