He served as Governor of New Jersey from 1947 to 1954 where he was a proponent for the New Jersey Turnpike and the Garden State Parkway. From the time of their construction, these two major transportation links would transform the agrarian "Garden State" into the most densely populated state in the union. The Driscoll Bridge on the Garden State Parkway across the Raritan River was named in his honor, and a failed planned extension of the New Jersey Turnpike (similar in nature to the Pennsylvania Turnpike's Northeast Extension) would have also borne his name. Driscoll served as a delegate to the Republican National Convention from New Jersey in 1948 and 1952, and he was considered for the vice presidential nomination at the 1952 convention.
