At some point in the Easy Eighties, the Department of Transportation did a little experiment with the pillars for the Jamaica El on Jamaica Avenue, placing square street signs on them. I noticed them on forays into Richmond Hill by bike from Bay Ridge back then, and finally got a few shots of them back in 2011. Here are a pair at Creegan Square where three lengthy routes, Jamaica Avenue, Myrtle Avenue, and Lefferts Boulevard meet, as well as an overhead (now freight-only) LIRR trestle; I once surmised it would have made a good transit hub, but others have since dissuaded me of the idea.
The signs appeared on pillars in the immediate area, but the idea wasn’t carried through elsewhere in Richmond Hill or Jamaica or any other elevated train. When the pillars were painted later in the decade, the signs were scrapped.
