For generations, I've seen map companies (most notably Hagstrom's) post a non-existent westbound loop on-ramp from Veterans Memorial Highway (before it was designated as NY 454), and the Long Island Expressway (back when it was still NY 495). Yet I've never seen this ramp, so I assumed it was something that existed years ago before the L.I.E. went east of Exit 57, and the map companies still hadn't caught on that it wasn't there anymore.
So within the hour, I was looking through some papers, which include hand-written notes regarding source material for the previous ramp and service road configurations for Wikipedia articles on the Long Island Expressway. Then I looked up Historic Aerials of the vicinity, and what I found was something I wish I could say was completely bonkers, but instead the most I can say is that those who set it up may have had a few screws loose.
Instead of a fairly reasonable temporary on-ramp, I saw westbound only turning ramps onto the eastbound service road, and northbound Blydenburgh Road, both of which lead to the eastbound on-ramp, which itself ended at a temporary U-turn to the westbound lanes of the expressway.
This has to be seen to be believed.
