was turned over to the county on October 6, 1966, while the segment between NY 24 and Knoll Road was given to Suffolk County on February 15, 1968. This section of Montauk Highway became CR 80, a route in length. The CR 80 designation was previously used for the Nesconset–Port Jefferson Highway, a road acquired by the New York State Department of Transportation (NYSDOT) and designated NY 347 in 1966. Although most of Montauk Highway between Patchogue and the village of Southampton was now maintained by the county, NY 27A continued to follow the road eastward to NY 27 northeast of Southampton. It was finally cut back to its current eastern terminus in Oakdale on March 29, 1972, after ownership and maintenance of Montauk Highway between Oakdale and CR 19 in Patchogue was transferred from the state to the county. The new county road was redesignated CR 85, a number used for the Smithtown Bypass until 1966, when that road was transferred to NYSDOT and designated NY 347. A section of Montauk Highway between Knoll Road to the west village line of Southampton at Tuckahoe Lane was retained by the state of New York and designated NY 900W, an unsigned reference route. Between the east end of CR 98 and the vicinity of the west end of CR 71, the Suffolk County Department of Public Works had once planned to widen the road from two lanes to four lanes. Realignments Over the years, Montauk Highway has been realigned in several locations. The former segments are now known by another name or as Old Montauk Highway, notably at Theodore Roosevelt County Park east of Montauk, where new Montauk Highway heads northeast through Montauk Point State Park while Old Montauk Highway heads east as a narrow hilly road next to the shoreline. Other significant realignments include the aforementioned rerouting between East Patchogue and Brookhaven and another in the vicinity of Eastport, where CR 71 (Old Country Road) was part of Montauk Highway between the current road and Eastport–Manor Road (CR 55). From there, Montauk Highway turned south along CR 55 to reconnect to its modern routing. Another former section is located between Montauk Beach and Montauk, where the modern road was altered to bypass the former to the north. The old road breaks from the current highway inside Hither Hills State Park and heads through Montauk Beach before rejoining the highway between
