Project of the Year

The nation's first diverging-diamond interchange in Springfield has been named a Public Works Project of the Year by the American Public Works Association.  

The interchange has been receiving widespread attention since it was completed in 2009. This type of interchange was first used in France, and has been shown to increase capacity, decrease congestion and minimize the cost of new infrastructure.

More diverging diamond interchanges are happening in Missouri, including a second interchange in Springfield, as well as projects in Kansas City, St. Louis and mid-Missouri.

If you're wondering just exactly how they work, watch below. Driven through one already? Let us know what you think!

Celebrate - Then Get Back to Work!

It's always fun to share success with friends.

MoDOT Motor Carrier Services got to do that at a recent ceremony, when our division and the MoDOT Springfield Area District received Governor's Awards for Quality and Productivity.

Motor Carrier Services earned honors in customer services. Our group handles the licensing of Missouri-based motor carriers. We also collect fees, taxes and enforce safety laws. Here's the big news: the people we license, tax and hold to the law are happy to work with us! In fact, 95.7 percent of them report they are satisfied - or very satisfied - with our service. A government agency. Wow.

We, in turn, are awed by our co-workers in southwest Missouri. The Springfield Area District earned the first-ever GAQP Pinnacle Award for constructing the first Diverging Diamond Interchange in the Western Hemisphere. The radical, lower-cost design dramatically improved safety and traffic flow in a heavily-congested area. They even completed the entire project in just six months. People found it easy to keep tabs on the project and quickly learned to use the "wrong" side of the road to get through the area quickly and safely. (I used to live nearby and am floored every time I drive through the area!)

It's very telling that even at the celebration, the two groups talked shop, discussing what new improvements could be made to the driving and freight-moving experience. It made me proud to be MoDOT.

A Winning Team

MoDOT has recently been awarded some top honors. This week it was announced that the Interstate 64 reconstruction project in St. Louis has been selected as the 2010 America's Transportation Awards Grand Prize Winner by the American Association of State Highway and Transportation Officials, AAA and the U.S. Chamber of Commerce. It competed as one of forty-three projects.

In addition, the new diverging diamond interchange in Springfield, Mo., won the Francis B. Francois Award for Innovation. The award goes to a project that brings value to the public. In this case, the interchange allows traffic to move faster, reduces congestion, increases safety and saves money.

Also, Interim Director Kevin Keith received the President's Transportation Award for Administration. He was recognized for exemplary service and impacting transportation by implementing Practical Design, a cost-saving strategy that has now become our standard way of doing business.

This recognition shows we're working hard to provide quality transportation and use resources wisely. Congratulations to all of those who worked with these projects and were a part of bringing about practical, innovative solutions to achieve tremendous results.

MoDOT Opens Nation’s First Diverging Diamond Interchange

Ever drive on the left side of the road? A highway design common in Europe is now giving Springfield, Mo. motorists this unique experience.

MoDOT opened the first-in-the-USA Diverging Diamond Interchange in June at the intersection of Kansas Expressway (Route 13) and Interstate 44 in Springfield.

Signs, pavement markings and concrete islands at the new interchange guide drivers on Route 13 as they criss-cross at traffic signals on both sides of the bridge at Interstate 44. That puts oncoming traffic on the right, but separated by concrete barriers that also form a pedestrian walkway down the center.

Left-turning vehicles on Kansas Expressway get a "free left" onto the I-44 on-ramps. At the same time, two lanes of traffic continuing north or south on Kansas Expressway are able to travel more steadily through the interchange.

A DDI is a great solution in high traffic areas. Motorists no longer have to cross opposing traffic. Left turn crashes are eliminated and the chance of being in a rear end crash is reduced. Motorists spend less time being stuck in traffic, which is also good for the environment as idle time is reduced at the interchange. Plus, Springfield’s DDI design came out to be cheaper and shaved about a year-and-a-half off the construction time.

Look for similar Diverging Diamond projects in Missouri, including one on National Avenue at the James River Freeway (Route 60) in Springfield and in Kansas City and St. Louis.
