Transit Queens-Midtown Tunnel turns 75; see rare photos of the first underwater road between Manhattan and LI By CRISTIAN SALAZAR Updated November 13, 2015 3:18 PM Print Share fbShare Tweet Email The first roadway under the East River to connect Manhattan and Long Island was a marvel of engineering when it opened 75 years ago. Officials formally welcomed the public into the Queens Midtown Tunnel on Nov. 15, 1940, but days before some 5,000 people were allowed to walk through the eastbound tube as a show of gratitude for having suffered through years of noisy, inconvenient construction on the Manhattan side. As they walked through the tube, their footsteps and voices echoed along with the barks of dogs that had been brought along by their owners. "What a bomb shelter this tunnel would make!" one person remarked, according to The New York Times, which reported on the "tunnel warming" on Nov. 11, 1940. It was actually President Franklin D. Roosevelt who was the first person to drive through the tunnel weeks before the public got to go inside. But it was a special day on Nov. 14 when ordinary New Yorkers finally got to pay their 25-cent tolls for the pleasure of steering their cars through the white-tiled tubes. The tunnel, actually two tubes that each stretch more than a mile under the East River, called for 'sandhogs' to excavate 10 stories below river bed through solid rock, sand, gravel, clay and even the wrecks of sunken barges. A special tunnel agency was created to secure federal funding, costing $58 million at the time. While the original brick roadway was replaced in 1995, the tunnel remained largely unchanged for decades from when it was first built until superstorm Sandy walloped the city and caused the tubes to be flooded for the first time in history. Salt water damaged the tunnel's lighting system, traffic lights and signals, height detection system and other infrastructure, the MTA said. The Metropolitan Transit Authority said on Nov, 10, 2015, that ongoing repairs are being covered by a four-year $236.5 million contract. "There will be nighttime and weekend tube and lane closures," said Raymond Webb, director of Tunnel Operations for MTA Bridges and tunnels, in a statement. However, "at least one tube will remain open at all times." Today, some 29 million trips are taken through the tunnel.

This boat, pictured on Nov. 30, 1936, was sent out to collect core samples ahead of construction.

According to the MTA, a combination of dynamite drills and 31-feet-in-diameter cutting devices known as shields were used to blow through the rock and earth under the riverbed.

Johnson The workers who carved the tunnel 10 stories below the surface of the East River, known as 'sandhogs,' had to be treated for decompression sickness in specialized chambers, as seen in his Dec. 28, 1938, photo. Sandhogs suffered more than 300 attacks of the bends, as decompression sickness is also called. Twenty-five attacks involved impairment of the central nervous system. There were no deaths.

The Queens-bound tube is 6,272 feet-long; the Manhattan-bound tube is 6,414 feet long.

They were called on to replace men who were away during World War II, but after the soldiers returned those jobs went away for women. This photo shows women on their first day of work, April 14, 1943. By CRISTIAN SALAZAR Share on Facebook Share on Twitter Comments We're revamping our Comments section.
