These are very efficient machines, enabling workers to lift snow away from congested roads. And no need for any work or broken roads.. I always like the big wheel loader blowers with their own power packs.  Seem to be almost the best solution.  The other one would be an excavator blower head with a srap on counterweight powerpack.  a couple of those in any city would be an enormous help eliminating the plow drifts.  The salter sweeper would be the king of the offramps... melt it and scrub it away before it refreazes.
