The original Abbey Road zebra crossing, where the photograph was taken, was moved several metres for traffic management reasons more than 30 years ago, and no original features remain.
My solution is to remove the fatal flaw at the heart of the system - the original sin of priority, because once you've removed priority you've removed the need for traffic lights and the need for speed because we're in no rush any more.
Yes, one very short stretch (no more than a few hundred feet) of Riverside Drive was covered in standing water and closed to traffic, though an SUV could have still driven through it on the day the Mississippi was at its highest.
