This is a difficult description to write because the mark is located on a street at a very new portion of the Big Dig which, to the best of my knowledge (and research on several official web sites), is unnamed. But here goes.
To get to the mark, the most sensible way is to start out at the intersection of Lincoln and Kneeland Streets in Chinatown. Go west along Kneeland Street for one block. Turn left at the intersection (which will have a Teradyne building and a building with a "Welcome To Chinadown" sign on it). You will now be walking on the eastern sidewalk of a frontage road that runs between Hudson St and I-93. Note that at the time of this writing, the sidewalk was sort of blocked by a construction barrier, but not fully (which I took as an invitation to continue).
Continuing up this frontage road (which, by the way, after going over I-90, turns into Albany St), you will come to an intersection with a stoplight. The road that intersects the frontage road goes over I-93 and into South Station, for what it's worth, but you should cross it at this point. You will then be at the southeast corner of the intersection. Continue walking down the frontage road as before.
After walking a ways (about 450 feet), you will reach the mark embedded in the sidewalk. I wish I had a better description, but there are few landmarks to go by here. It's about 2/3 of the way between two metal plates in the sidewalk, but those plates are quite a way apart (like 100-200 feet). If you pass the "Exit 18 1/2 Mile" sign on the freeway to your left, you've gone too far.
Another good way to look at the location is to note that I-93 to your left is inclining, while your are on a downward slope. The mark is located at a point where the level of the sidewalk is still a couple feet above the level of the highway.
