The Keyport and Oak Grove Turnpike was a proposed turnpike in New Jersey, running south from Keyport to Oak Grove, on the border of Holmdel and Aberdeen townships. The proposed route began at the Monmouth County Plank Road (now Maple Place) in Keyport, and is now followed by Broadway, Lloyd Road and Line Road south to Van Brakle Road.
The Keyport and Oak Grove Turnpike was chartered on February 23, 1870.[1] It was never built.
