The Cross County Parkway (CCP) is a parkway in lower Westchester County, New York, in the United States. The parkway is a critical east–west connection throughout Westchester, having full interchanges with every major north–south highway in southern Westchester with the exception of Interstate 95 (New England Thruway). Among its junctions, it has access to the New York State Thruway mainline. The western terminus is at the Saw Mill Parkway in Yonkers. The eastern terminus is at the Hutchinson River Parkway in New Rochelle. As evident from stubs and oversized overpasses, it appears that there were plans to expand the Parkway west from Exit 2 to Downtown Yonkers and east from Exit 9 to I-95. World War II had slowed this idea until it was shelved. The CCP is the only parkway in New York state that has express and local lanes. The parkway is designated New York State Route 907K (NY 907K), an unsigned reference route. Route description The Cross County Parkway begins at an interchange with the Saw Mill River Parkway in Yonkers. Exits 1 and 2 are part of this interchange, with Exit 1 being a westbound only exit to Rumsey Road, and Exit 2 being a westbound exit/eastbound entrance from the Saw Mill northbound. The entrance/exit at the Saw Mill southbound has no number. The eastbound entrance at Exit 1 (Rumsey Road) is via the Saw Mill southbound. After crossing an abandoned railroad grade, the parkway enters Exit 3, a small interchange with Yonkers Avenue. The six-lane roadway crosses through southeast Yonkers, making a gradual bend from the northeast to the southeast before spitting into express and local lanes. The parkway then enters an interchange with the New York State Thruway (I-87) and NY 100, Exits 4S (for I-87 south) and 4N (for I-87 north/NY-100 north). All exits/entrances are accessed here by the local lanes, except for the eastbound exit and westbound entrance at Exit 4N, which are via the express lanes. The eastbound entrance at Exit 4N connects to both the express and local lanes. Shortly after, the Cross County enters Exit 5, which connects to Kimball Avenue and Midland Avenue and is only accessed by the local lanes. There is no eastbound entrance. Continuing east through Yonkers, the Cross County Parkway enters an interchange with the Bronx River Parkway and Sprain Brook Parkway, Exit 6.
