High Quality Content by WIKIPEDIA articles! Ocean Highway was a designation established early in the 20th century for a combination of roadways and water-crossings for motor vehicles which would generally traverse as close as possible to the Atlantic Ocean along the East Coast of the United States from Jacksonville, Florida to New Brunswick, New Jersey. The Ocean Highway concept predated the creation of the Interstate Highway System beginning in the 1950s, and in many states the highways and byways of coastal routes from Florida to New Brunswick still carry the name.
