Long Description:
The CA/T, or Central Artery/Tunnel project, aka the (notorious) Big Dig, has been a ongoing construction project through the center of Boston. It would seem that they've been installing marks in the areas in which they've been working.

This mark can be found on the northern side of Causeway Street, just east of the former site of the Artery (now underground), approximately at the intersection of Medford St and Causeway. The mark is smaller than most NGS marks, and is approximately 2 feet from the northern edge of the sidewalk, north of two large, round manhole covers.
