Long Description:
This mark is located in the Chinatown section of Boston at the southeast corner of Marginal Rd (which turns into Hudson Rd) and Harrison Ave. It is embedded into the sidewalk just north of the expansion joint in Harrison Ave as it goes over I-90, and is just a few inches from the granite curb.

The mark is referenced by writing in white paint on the metal endpost of the railing along the bridge. While probably intended to be temporary, it has already lasted for a period of time, and reads as follows:
"by m.t.
8-24-2000
Tie to ->
8.0 feet off 503
CA/T disk
<-"
(That last arrow actually points down and to the left.)
