How fun to find this bridge! 4 benchmarks right on it, and 2 more nearby. This one is painted over, but still legible (barely).

HS3095, HS3096, HS3097, and HS3098 are four benchmarks all on the same side of the bridge on William Street near 18th Street. This cement guardrail and the disks are over 71 years old and are in excellent condition. This is the 2nd one from the north end.
