Missouri must be given KUDOS for their courage to think outside the box. We have seen other efforts like this but this one finally hits home as a serious retrofittable interchange solution.

I-44/Route 13 Interchange
Reconstruction:Diverging Diamond Design


Most interchanges resemble large paring lots with gates and once the demand exceeds capacity the excess backs up onto to the interstate, causing accidents, flow chaos and destruction of flow capacity.

This solution improves every aspect while reducing the conflict zones, while the excess demand for the surface streets does not overflow onto the interstate.

We have a solution to enhance guidance and further reduce possible confusion, day or night; nonetheless YES.
