Jones Beach Causeway (now part of the Wantagh State Parkway). The parkway was named after Meadow Brook, the stream that follows its route between East Meadow and Freeport. Construction of the Meadowbrook Causeway began in May 1933 with a $5,050,000 loan (1933 USD) given from the Reconstruction Finance Corporation to the Long Island State Park Commission in April 1933. In order to repay this loan, the Long Island State Park Commission, working with the Jones Beach State Parkway Authority, would institute a 25-cent toll on the Meadowbrook and Jones Beach causeways. The 50-cent parking fee on Jones Beach would be reduced to 25 cents in order to keep the total charged to motorists at 50 cents. It was proposed that the loan would be repaid in 25 years. The Meadowbrook Causeway was designed as a road from the Southern State Parkway in Freeport to Jones Beach with six bridges across channels of South Oyster Bay. Three grade-separating structures would be designed as well by the State of New York Department of Public Works and the LISPC. A trumpet interchange with the Lido Beach Loop Causeway (current-day Loop Parkway) was constructed as well. Designs also included 10.1 million cubic yards of hydraulic fill, and a new water channel for boats. Proposed completion of the project was set for January 1, 1935. The road was constructed by 3,800 people and completed in October 1934, six months ahead of schedule. On October 27, 1934, the Meadowbrook and Lido Beach Loop causeways were opened to vehicular traffic by LISPC. A motorcade of cars was led across the new roadways by Robert Moses, then a Republican Party candidate for Governor of New York. The event was preceded by parades in Freeport and Rockville Centre. During a speech Moses cited praises to the Reconstruction Finance Corporation for donating the money and letting the LISPC and Jones Beach State Parkway Authority do the work without interference. Other speakers that afternoon praised Moses and the LISPC, and New York City Mayor Fiorello La Guardia showed up late to give his congratulations. Despite the opening ceremony, two-way traffic was not permitted on the Meadowbrook between the Southern State and Merrick Road until June 1, 1935. Prior to that time, motorists had to use the renamed Wantagh Causeway to access Jones Beach. Extension to the Northern State Parkway Moses announced during the opening of the Bethpage State Parkway in November
