Bicycles aren't allowed at this cemetery. (I rode through today, having not seen the signage, and a very polite groundskeeper asked me not to do this.)

This path is behind a locked gate with signage that indicates that this area is not accessible to the general public.

The zigzag ramp from the sidewalk leads to a door here, with two signs:

DO NOT ENTER, MBTA EMERGENCY EXIT ONLY

DANGER, LIVE TRAINS - NO ENTRY WITHOUT FLAGGER, FOR ACCESS CALL GREEN LINE DISPATCH AT 617-nnn-nnnn, DO NOT ENTER

The footpath beyond here exists, but is only accessible to the public if the Union Square station is being evacuated in an emergency situation, so it should be marked as locked or inaccessible or similar.

There’s a locked gate here, with a sign:

“NO TRESPASSING, Federal Property, Violators will be prosecuted, 41 CFR 102-74.385”.

The footpath beyond this is therefore inaccessible to the public.

This school has been demolished and this driveway is now a construction site. The future configuration of this site may or may not include a drivable route here. Until the construction finishes, this should probably be removed from the database, or annoyed as “gated-access” or similar.

There is currently a barricade here, and a construction site on the northern end of Cross St from here to Mystic Avenue. It isn't clear to me if the street will ever reopen in its previous configuration. This segment should be annotated as “gated access” or similar.

This segment seems to be annotated as a public path, but it's somebody’s yard, with a fence around it and a gate at each end of the marked path. This is somebody’s home, and does not appear to be intended as a public pathway.
