The company bid $12.7 million for the project. The interchange is part of a larger project around Stadium Boulevard that will widen lanes and create a sixth lane with divided roadways. It will also add lanes to Fairview Road from Worley Avenue to west of Columbia Mall and Bernadette Drive.The full project is estimated to cost $19.6 million. The corridor improvements are funded by the City of Columbia, MoDOT and three Transportation Development Districts.
Columbia Fire Marshal, Brad Fraizer said, "Stadium Boulevard and Bernadette Drive is an area where we see tremendous amounts of accidents. We're confident that improvements to that portion of Stadium will decrease the number of vehicle accidents and decrease the amount of traffic allowing an increase in emergency response times."
The new diamond interchange will also help emergency responders and commuters be able to get to I-70 faster.
The new route will criss-cross the roads and allow left lane of traffic to flow straight off of Stadium on to I-70.
This type of "diverging diamond interchange" can also be found in Springfield, Missouri at I-44 and MO-13.
