The I-69 and S.R. 1 (Dupont Road) interchange will be modified from a traditional diamond interchange to a Diverging Diamond Interchange (DDI). The DDI modification will take Dupont Road traffic to the left side of the roadway as it crosses the bridge between the I-69 northbound and southbound ramps. Once on the left side of Dupont Road, vehicles can turn left onto the interchange ramps without stopping and without conflicting with through traffic.
