Somerville

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.
