I-70 AND MID RIVERS MALL DRIVE INTERCHANGE - COMPLETED IN 2013

 

DDI Drawing Public HearingProject Cost: $12.5 million ($7 million from federal Congestion Mitigation Air Quality grant; $4.3 million from Missouri Department of Transportation; $834,000 from St. Charles County half-cent transportation sales tax; $425,000 from the City of St. Peters)

Contractor: Millstone Bangert

Scope: A major interchange reconstruction project addressed the congestion problem at the Interstate 70 and Mid Rivers Mall Drive interchange. Congestion was affecting traffic exiting Interstate 70, motorists entering and exiting Mid Rivers Mall, and interchange access to Main Street in Old Town St. Peters. More than 160,000 vehicles daily use this section of I-70 between Mid Rivers Mall Drive and Route 79. This project also added a westbound I-70 lane between Mid Rivers Mall Drive and Route 79. This project allows traffic to move more freely on Mid Rivers Mall Drive near Mid Rivers Mall and other commercial areas.

Diverging Diamond Interchange: MoDOT, in conjunction with the City of St. Peters and St. Charles County, reconstructed the interchange as a diverging diamond interchange (DDI). MoDOT has built numerous diverging diamond interchanges throughout the state, including the first DDI in the St. Louis region at the Interstate 270 and Dorsett Road interchange. The diverging diamond interchange (DDI) is a new type of interchange traffic solution. The Federal Highway Administration has been advocating innovative intersection designs as a way to increase capacity, decrease congestion and minimize the cost of new infrastructure. The advantages of a DDI include making left turns without crossing opposing traffic, and improvements in signal timing due to the reduction in the number of traffic movements for each cycle. Plus, there is increased efficiency and capacity of traffic at entrance and exit ramps of the interstate. Traffic models indicate this type of interchange works well with areas of heavy traffic. Because the DDI does not have any left turns that must clear opposing traffic, the design can improve traffic movement with more green time. It moves traffic faster, reduces congestion, and improves safety.
