While walking back from my weekly ultimate frisbee
game on the Esplanade
, I noticed an odd sign suspended above Storrow Drive
Westbound in Boston
. The large road sign was hanging below a bridge and read "Reverse Curve." After thinking about it, I realized I had no idea what this meant.
provides this illuminating
Reverse curve (Railways), a curve like the letter S, formed of two curves bending in opposite directions.
Another one for road signs we do not understand
