CR 48, named Middle Road, starts just west of an at-grade intersection with Cox Neck Road and Sound Avenue west of the
hamlet of
Mattituck in the
town of Southold. From there through
Southold, the road becomes four lanes wide. Besides Wickham Avenue, the road intersects with Mill Lane (former
CR 84) to
Oregon; Elijah's Lane, which crosses the road after the east end of Wickham Avenue; Depot Lane in
Cutchogue, which leads to both the former
Cutchogue railroad station and Duck Pond Point; and Bridge Lane, which was named for a railroad bridge over the
Main Line of the
Long Island Rail Road. In
Peconic, the route intersects Mill and Peconic lanes (the latter is the main road to the former
Peconic railroad station while the former leads to Goldsmith's Inlet County Park on the
North Shore). East of Ackerly Pond Road in Southold, the road becomes two lanes wide. The first streets that the road encounters are Kenny's Road and Horton Lane, both of which have north shore beaches in their namesake. Unlike Kenny's Road, Horton Lane spans as far south as the Southold Town Hall on
NY 25, as does Youngs Avenue, which leads to
Southold's railroad station and the
Horton Point Lighthouse. The road takes a brief northeast turn at the intersection of Boisseau Avenue before moving back toward the east at North Road. As the road approaches Hashamomuck Pond, it replaces Sound View Avenue as the northernmost road on the North Fork. Sound View Avenue leads to Goldsmith's Inlet County Park, Peconic Dunes County Park,
Horton Point Light and Hashamomuck Beach. Between Hashamomuck Pond and
Greenport West, a section of Middle Road near a motel with the
Long Island Sound in the back yard is still paved with concrete, as it was commonly done during the late 1920s and early 1930s. The section of old-fashioned pavement, however, is short-lived. Along the border of Greenport, the road encounters a former
KOA Campground, which today is the privately owned Eastern Long Island Kampground. It also runs along the southern border of Inlet Point County Park, and intersects Moore's Lane as it runs north of the village. CR 48 finally ends at NY 25 on the border between Greenport and Stirling, with CR 48's right of way continuing eastward toward
Orient Point as NY 25. All of CR 48 is part of
NY 25 Truck, a truck route of NY 25 that runs between
Laurel and Greenport. ==History==
