Bridges In 1917, the Hell Gate Bridge, a railroad bridge, was built across both islands, running from Astoria, Queens to the Bronx. The bridge was first thought of in the early 1900s, as a plan to link New York and the Pennsylvania Railroad with New England and the New Haven Railroad. The bridge is considered to be extremely sturdy; it would be the last New York City bridge to collapse if humans disappeared, taking at least a millennium to do so, according to the February 2005 issue of Discover magazine, while most other bridges would fall in about 300 years. In 1936, the islands were connected to the rest of the city by the Triborough Bridge, the hub of which crossed the islands. The American Society of Civil Engineers designated the Triborough Bridge Project as a National Historic Civil Engineering Landmark in 1986. On November 19, 2008, the Triborough Bridge was officially renamed after Robert F. Kennedy at the request of the Kennedy family. To manage the bridge (and eventually all tolled New York City water crossings), the Triborough Bridge and Tunnel Authority erected an art deco head building, the former base of Robert Moses; the building still stands on the island. In 1937, the islands were connected by a bridge over Little Hell Gate, obviating the need for a ferry to Wards Island. There were two bridges that appear to have been known as Little Hell Gate Bridge – an early 20th-century rail bridge on the approach to Hell Gate Bridge, and a later, lower steel arch road bridge across Little Hell Gate. The northern approach viaduct to the Hell Gate Bridge included an inverted bowstring truss bridge, with four long spans, across Little Hell Gate. Although the majority of Little Hell Gate has been filled in, this bridge still exists. Some time after the rail bridge was built, a long, 3 span, steel arch road bridge, designed by George Washington Bridge-engineer Othmar Ammann, was also built across Little Hell Gate, just a short distance to the northwest of the rail bridge. The Little Hell Gate bridge was rendered obsolete when the Little Hell Gate was filled, and a service road was built alongside the deteriorating bridge. Efforts were made in the mid-1990s to
