Can the cloverleaf be improved?
They are considering putting in a "diverging diamond" interchange in Norwalk, very close to DR ChasSmith.
This type of highway interchange became popular in France during the 1970s and has started to become popular in the American midwest. Each direction of traffice briefy crosses over to the opposite side of the road between the on- and off- ramps, eliminating the need for drivers to cross oncoming traffic, theoretically resulting in less bottlenecking.
