Alternatively, the company I work for can do it with LiDAR.  Vertical Clearance Measurement for overhead structures is sometimes a deliverable for our customers.

It's the LIRR Port Washington Branch over East Shore Road in Great Neck just before the Manhasset Viaduct.

This.  You might not even know if a bridge is under 16'0", depending on the state, because they don't bother posting above a different threshold.

I'm not so sure that's true.  :-D

It may not be true for inches, but it's definitely true for feet.  Here are some examples just from my home state of Kansas

14'4" — I-35, South Haven
15'0" — I-135, Wichita
15'3" — I-70, Voda

The I-35 portion of the Kansas Turnpike has multiple 14'0" bridges.  I'd show you some GSV examples, but the KTA doesn't label vertical clearances—meaning I'd be showing you a 14'0" bridge with no yellow plaque on the structure at all.  Well, OK, why not?  Here's one:  Bazaar Cattle Crossing, 14'0" in both directions.
