Roosevelt Island residents and distinguished guests gather to mark the 40th anniversary of the maiden voyage of the Roosevelt Island aerial tram on Tuesday, May 17 at 1:00 pm at Tram Plaza. Join us for a celebration featuring remarks by those who were instrumental in the life of the tram, plus a performance by the PS/IS 217 Band. Children of the island will share model tram cabs they have decorated. Bring your stories of unusual events (marriage proposals and weddings), celebrity sightings (Harrison Ford) and exotic guests (deer). A cake, in the form of the tram, will be served. FREE.
