As crews with the Missouri Department of Transportation put the finishing touches on its latest diverging diamond interchange in Springfield, motorists are to be aware of lane closures.
During times this week and weekend officials plan to close Kansas Expressway at James River Freeway, the site of the fourth diverging diamond in the city. The first such intersection in the nation was constructed in 2009 about eight miles north, where Kansas intersects Interstate 44.
The intersection at James River and both ramps will be closed Wednesday night into Thursday morning, and again from Saturday evening to Monday morning. Once reopened, the new $2.6 million interchange, will be complete.
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.
Just last week, MoDOT held a meeting seeking public comment on yet another such intersection in Springfield, along the Battlefield Road bridge over Route 65. Construction on that project is planned for 2015.
