Location: I-70 and Stadium Boulevard (Route 740) in Columbia

What is a Diverging Diamond Interchange? Why is it Safer?
This innovative traffic solution is located at I-70 and Stadium Boulevard (Route 740) in the Central District and handles high traffic volumes effeciently, resulting in less congestion and overall improved safety. The configuration accomplishes this by allowing free-flowing left turns for motorists. These free-flowing left turns keep traffic moving and keep vehicles from crossing opposing traffic, thereby reducing the chances of a collision.


What does it look like?

How Does it Work?

Motorists on Stadium entering the interchange are directed to the opposite side of the roadway after traveling through a set of traffic lights. Those who want to get on the interstate turn left onto the ramp without stopping for more lights or crossing opposing traffic, while drivers going straight proceed through a second set of traffic lights redirecting them to the right side of the road after leaving the interchange.

With the opening of the diverging diamond interchange, a major component of the I-70/Stadium Boulevard highway construction project is complete. However, a great deal of work remains, including the widening of Stadium Boulevard from Interstate 70 to south of Broadway. Bernadette Drive from Knipp Street to Beverly Drive is also being widened as part of the work. The entire project is scheduled for completion in winter of 2014. The $12.8 million job is funded through a cost-share agreement between MoDOT, the City of Columbia and three transportation development districts.
