Kansas Expressway will be closed between James River Freeway and Chesterfield Boulevard, and the freeway ramps will be closed from 8 tonight through Sunday morning. Delays might extend the closure through Monday morning.
During the closing, crews will continue work to convert that interchange into a diverging diamond.
Once the interchange opens back up, drivers will need to use caution since the traffic pattern will have changed into a diverging diamond.
The work was scheduled to be finished two weeks ago but was postponed due to heavy rains.
The crisscross pattern of the diverging diamond allows drivers to make free left handed turns instead of having to wait for oncoming traffic, and transportation officials credit it as a quicker, cheaper, and safer means of travel.
Springfield has three other diverging diamond interchanges—at Kansas and I-44, at Chestnut and Highway 65 and at National and James River Freeway. Another diverging diamond is planned for Battlefield and Highway 65.
Other road work over the next few days will close lanes on James River Freeway. One eastbound lane of the freeway will be closed at times between Glenstone and 65, and the eastbound on-ramp from Glenstone to James River freeway will be closed from 8 pm to 5 am Sunday through Thursday (8/18-8/22) while crews make pavement repairs.
