This stamp is from Lathrop Street south of Elizabeth, on the west side of the street. The sidewalk ends here. On the east side of the street it continues, as Lathrop curves around to meet Allen. Unlike other streets nearby that were truncated by the construction of I-496 in the late 1960s, Lathrop would always have ended more or less here, because Stabler Park lay to the south. The turn that joins Lathrop to Allen is now a bit diagonal, in parallel to 496, whereas it used to be more squared off (as I can see on HistoricAerials.com). The result is that while the last house on the east side has survived, the last two on the west side were 496 casualties.

The stamp is on the very last piece of sidewalk on the west side, and I find it odd that it extends a little past the driveway for no apparent reason. Since it’s dated 1988, it was laid long after any houses existed to the south. My guess is that it marks the lot line. The doomed house that used to be next door to this one, 628 Lathrop, sold in 1957 for $6,800 cash. The real estate card notes that it had a dark room in the basement.
