 The at-grade interchange with CR 104 was built for one purpose; a future extension into Central Suffolk County.The at-grade interchange was to be upgraded to a real interchange, as was the case with many existing intersections.From there, the road was to run west through the David A. Sarnoff Pine Barrens Preserve, then was to cross over CR 88 (Speonk–Riverhead Road), where it was to turn north as it ran along the south and west sides of the Suffolk County Community College Eastern Campus before crossing over CR 51 at Bald Hill.
