South Beach's main streets (5th Street, Alton Road, Collins Avenue, Washington Avenue, and Ocean Drive) were all suitable for automobile traffic. In 1920, the Miami Beach land boom began. To this day, this area is known as Lummus Park. The Lummus brothers sold their oceanfront property, between 6th and 14th Streets, to the city. In 1920, the County Causeway (renamed MacArthur Causeway in 1942 ) was completed. On March 26, 1915, Collins, Lummus, and Fisher consolidated their efforts and incorporated the Town of Miami Beach. The Collins Bridge was later replaced by the Venetian Causeway. Fisher loaned $50,000 to Collins for his bridge, which was completed in June, 1913. This was the same year that the restaurant Joe's Stone Crab opened. His vision was to establish South Beach as a successful city independent of Miami. Fisher, a successful entrepreneur who made millions in 1909 after selling a business to Union Carbide, came to the beach in 1913. Although some local residents invested in the bridge, Collins ran short of money before he could complete it. In 1913, Collins started construction of a bridge from Miami to Miami Beach.

In 1912, Miami businessmen the Lummus Brothers acquired 400 acres (160 ha) of Collins' land in an effort to build an oceanfront city of modest single family residences.

He used the land for farming purposes, discovering fresh water and extending his parcel from 14th Street to 67th in 1907. In 1894, the Lum brothers left the island, leaving control of the plantation to John Collins, who came to South Beach two years later to survey the land. Charles Lum built the first house on the beach in 1886. In 1870, Henry and Charles Lum purchased 165 acres (67 ha) for coconut farming.
