The nation's first diverging diamond interchange is now open at I-44 and Kansas Expressway in Springfield.

MoDOT says the diverging diamond should improve traffic flow at the busy spot, though the change has been confusing for a few folks as they try to head down the wrong side of the interchange.

Crews are still putting the finishing touches on timing the lights and have some concrete work left to do. MoDOT should finish the project by July 3.

Cost of for the project was about $3 million or one-third the price of a traditional interchange redesign.

MoDOT is putting in another diverging diamond at James River Freeway and National. http://www.kspr.com/news/whereyoulive/greene/48769012.html
