Exit 40 originally had only same-directional off-ramps under the expressway providing access to realigned sections of NY 25. When exit 41 was originally constructed, it had no south-to-west connecting ramp. Westbound access to the expressway was provided at the nearby exit 40 on-ramp at NY 25. An alternate design for exit 42 called for it to be similar to the one proposed for NY 135 and Bethpage State Parkway, and westbound exit 46 was originally a partial cloverleaf. Exit 47 was intended for the extension of the Bethpage State Parkway near Washington Avenue in Plainview. This was to be a partial cloverleaf with southbound-only off-ramps and northbound-only on-ramps in both directions. The west-to-southbound ramp would also have an additional connecting ramp to a two-way frontage road for a development and an industrial area near exit 46. The site of exit 47 is now a truck inspection site between exits 46 and 48, which opened in 2006.
