THERE IS A SILVER BULLET TO DEAL WITH TRAFFIC CONGESTION.

I could file this post under "first world problems."  There is a subset of traffic engineers, or perhaps of highway departments more generally, for whom keeping the traffic moving freely is the categorical imperative, never mind the effects on pedestrian safety (multi-lane roundabouts) or bicycle safety (slip ramps, diverging diamond interchanges).

The following video illustrates an intramural squabble among defenders of the diverging diamond and its critics.  The clip begins toward the end of the clip, as Charles "Strong Towns" Marohn wanted his readers to catch the (erroneous?) disagreement the producer of the clip made.  Feel free to refresh to see the whole thing.

I don't have a dog in the traffic engineering fight, if eliminating four left-turn-arrow cycles by flopping the traffic lanes across the bridge is worth the risk to pedestrians and bicycles who must play two screens of Frogger to get from a sidewalk at the near end to a sidewalk at the far end is good policy, fine.

But when the producer says "there's no silver bullet for traffic congestion," there he lost me.

The roads are productive assets.  Price them accordingly.
