George Gordon Battle, a Tammany Hall attorney, was appointed as chairman of the new authority, and three commissioners were appointed.  However, the loan would only be given under a condition that 18,000 workers be hired first, so the city's Board of Estimate voted to hire 18,000 workers to work on the Triborough project.  However, although the RFC favored a loan for the Triborough project, the new mayor, John P. O'Brien, banned the RFC from giving loans to the city.  The preliminary Triborough Bridge proposal comprised four bridges: a suspension span across the East River to Queens; a truss span across Bronx Kill to the Bronx; a fixed span across the Harlem River to Manhattan; and a steel arch viaduct across the no-longer-extant Little Hell Gate between Randalls and Wards Islands. In 1969, the Manhattan span's toll plaza was relocated west and the I-278 toll plaza was relocated south, and both toll plazas were expanded more than threefold. The Bronx Kill span is a truss bridge that connects the Bronx with Randalls Island. The Triborough Bridge (known officially as the Robert F. Kennedy Bridge, and also known as the RFK Triborough Bridge, the RFK Bridge, or simply the RFK) is a complex of bridges and elevated expressway viaducts in New York City.  Also part of the complex is a grade-separated T-interchange on Randalls Island, which sorted out traffic in a way that ensured that drivers paid a toll at only one bank of tollbooths.  Smaller parks were also built in Astoria and Manhattan. Their duties on these facilities are to preserve the public peace, prevent crime, and arrest offenders.  Although I-278 is signed as a west-east highway, the orientation of I-278 on the bridge is closer to a north-south alignment, with the southbound roadway carrying westbound traffic, and the northbound roadway carrying eastbound traffic.

However, it could be replaced with a lift bridge if needed.  Following this, in September 1927, a group of entrepreneurs proposed to fund the bridge privately. Weekday afternoons: 3 lanes to Queens; 2 lanes to Bronx.  Traffic from the Manhattan span was temporarily diverted during this project. , The interchange plaza connects with the over-water spans via a three-legged concrete viaduct that has a total length of more than 2.5 miles (4.0 km).  The New York City Department of Hospitals later decided to apply for funds to build the Seaview Hospital on Staten Island, which would house the hospital facilities displaced by the Triborough Bridge.  In addition, Moses wanted to build an elevated expressway atop Bruckner Boulevard.
