The New Jersey Turnpike has lanes that are 12 feet long.
 The number of lanes ranges from four lanes south of exit 4 (Mount Laurel Township), six lanes between exit 4 and exit 6 (Mansfield Township), 12 lanes between exit 6 and exit 11 (Woodbridge Township), and 14 lanes between exit 11 and exit 14 (Newark)
 Instead, in 1948, the New Jersey Turnpike Authority was created to build the road, and the two freeways were built as a single toll road
