From a 1949 map by Triboro Bridge and Tunnel showing proposed highway connections throughout NYC that were never completed, including:
- Lower Manhattan Expressway
- Eastern Parkway extension, a controlled access connection to the Interborough Parkway (Jackie Robinson)
- Nassau Expressway and an original layout of Idlewild Airport
- Richmond Parkway, Willowbrook Parkway, and an alternative routing of the Staten Island Expressway before the Verrazona-Narrows Bridge was built.
