	On April 24, 1925, Governor Al Smith signed a bill authorizing the construction of the highway. Funds for the $11 million highway were to be procured by property assessments along the route; this was considered reasonable due to advantages gained from the highway by those living along the route. The road was to be , five feet wider than Fifth Avenue, with a speed limit of at least , and would be off the ground. It would be built of steel, with a cement face. A three-foot (1 m) sidewalk would be built for pedestrians, although the highway was intended mainly for motor vehicles. Two-block-long ramps would be provided with easy grades for entering and exiting the highway. Trucks would be allowed on the highway.
