Randy Weiss finds this sign just a couple blocks down the street from Gerry’s Landing. This area seems to be a veritable gold mine of mathematically significant signs. The variety of single-digit roads with short distances to towns create endless possibilities.
The math here is a matter of powers of 2.
2 \times 4 \times (5 - 3) = 16
This sign is on Huron street, at the intersection with Fresh Pond Parkway in Cambridge, Massachusetts. The GPS coordinates are approximately N42.38006 W71.14453. See sign on map!

4 squared is 16
numbers make me queezy, but even I can see that.
Stand up Thingle-thing, give this sign the 8.35 it deserves!

Tsk tsk tsk.. the rules are the rules. First of all, the series you suggest is invalid, you are splitting the 16 to make a 1 and a 6, clearly against the rules. And your 4^2 = 16 is completely ridiculous. It’s as if the 3 and the 5 were not even on the sign.
These suggestions are simply invalid.

16 - (sqr. rt.(4) / 2) = 5 x 3
