The Seaford-Oyster Bay Expressway begins at a highway-from-where ending at Jericho Turnpike (NY 25). There is an exit leading back to Jericho Turnpike (NY 25), but it's unsigned because that's where all traffic is coming from and there's no reason for anyone to use it.

Exits 1W-E are for Merrick Road (CR 27). The expressway ends here and all vehicles that do not use exit 1W are forced onto the ramp for exit 1E. The road was supposed to continue, curving to the southwest to end at the Wantagh Parkway and provide access to Jones Beach. Based on the way that the pavement and divider end at a fence, it is clear that this road was not supposed to end here.
