The first boardwalk built in the United States was in Atlantic City, New Jersey in 1870. A petition was presented to City Council on April 25, 1870 for the construction of a footwalk on the beach, and $5,000 in funds was allocated for construction. The footwalk opened to the public on June 26, 1870 and was eight feet wide, one mile long, and stood approximately one foot above the sand. Twenty-five years later Boardwalk was made an official street name in Atlantic City. (As an official street name, Boardwalk is always capitalized when referring to the street in Atlantic City.)

The deck of the Atlantic City Boardwalk is made of specially-treated yellow Southern pine with Douglas fir joists. As of 2001, the City Engineer uses Bethabara, a Brazilian wood, to replace damaged planks in the Boardwalk. The herringbone pattern dates from 1916. The Boardwalk’s supports are concrete-encased steel beams. The railings are galvanized aluminum.

The current length of the Atlantic City Boardwalk is a little more than 4 miles. At the widest point, it is 60 feet wide, and it stands 12 feet above sea level. The combined length of the current Atlantic City and Ventnor Boardwalks is approximately 5.75 miles. The historic length of the Boardwalk, before the 1944 hurricane, was about 7 miles and it extended from Atlantic City, through Ventnor and Margate into Longport.

Over the years, the Boardwalk has been reconstructed to provide better access and stability:

• The 2nd Boardwalk constructed in Atlantic City was opened about June, 1, 1880.
• The 3rd Boardwalk opened about June 1, 1884.
• The 4th Boardwalk was dedicated May 10, 1890.
• The 5th Boardwalk was dedicated July 8, 1896.
