Miami’s engineering masterpiece

Far more than just a bridge, the MacArthur Causeway is a colossal six-lane engineering marvel linking the city and buzzing Miami Beach. It crosses the tranquil Biscayne Bay, connecting the islands to the mainland and offering stunning views of the city’s imposing skyline.

Feel like exploring the bay? Big Bus Tours will carry you over the causeway to the sunny shores of Miami Beach, passing Palm Island, Dodge Island and Star Island – the exclusive neighbourhood of many celebrities. It’s also worth keeping an eye out for the small but quaint Flagler Memorial Island while on our Miami Bus Tour.

History of the MacArthur Causeway

Back at the start of the 20th century, the crumbling wooden Collins Bridge (now the Venetian Causeway) was the only link between Miami city and the Barrier Islands. As Miami Beach transformed into a world-class Art Deco resort, the city needed a new bridge, and construction of the MacArthur Causeway began in 1917.
