Just as archaeologists search for arrowheads to ascertain ancient Native American settlements, so do I look for arrowheads — arrowhead signs that point the way to NYC bridges. These first appeared in the 1930s, and while they have given way to larger directional signs, newer versions of these have actually appeared as painted arrowheads within standard rectangular signs.
Occasionally you still find one of the originals, like this one at Pratt and Strang Avenes in Eastchester in the NE Bronx. There are similar signs pointing toward tunnels, but they are circular.
