Exit 52 (Commack Road/CR 4) was intended to be moved west to an interchange with the formerly proposed Babylon–Northport Expressway (realigned NY 231) in the vicinity of the two parking areas. These ramps would have been accessible from the service roads. The westbound off-ramp and service road at exit 54 (Wicks Road/CR 7) originally terminated at Long Island Motor Parkway, east of Wicks Road. The westbound on-ramp was squeezed between the northwest corner of the Wicks Road bridge and exit 53. Excessive weaving between exits 52, 53, and 54 caused NYSDOT to reconstruct all three interchanges into one, and replace the west-to-southbound off-ramp to Sagtikos State Parkway with a flyover ramp. Exit 55A was meant to be a trumpet interchange for the Hauppauge Spur of NY 347, between Long Island Motor Parkway (exit 55) and NY 111 (exit 56). The service roads were intended to go around the interchange, rather than run parallel to the main road. Ramps on the east side of Motor Parkway and west side of NY 111 would be eliminated as part of the interchange's construction. Between exits 57 and 58, there was a proposed extension of Northern State Parkway.
