The Nassau Expressway was originally known as I-78, with I-878 on the Bruckner Expressway; after the cancellation of the Lower Manhattan Expressway, the Nassau Expressway and the Cross-Brooklyn Expressway were designated I-878. After the cancellation of the Cross-Brooklyn Expressway, I-878 was resigned NY 878.
