Welcome back, Nora!
The last time that Nora, the tunnel boring machine, saw any sunlight was late in 2017, before she was lowered down a shaft on the west side of the Hudson River.
For nearly the past two years, she has been excavating eastward, underneath the Hudson River, to create the Delaware Aqueduct Bypass Tunnel. The bypass tunnel is part of a one BILLION dollar project to repair two areas of leakage within the 85-mile Delaware Aqueduct—the longest tunnel in the world.
Now that her job is finished, she’s being lifted out in segments from a shaft on the east side of the Hudson River.
About Nora
Nora is one of the world’s most advanced tunnel boring machines. When fully assembled, she measures more than 470 feet long and weighs upwards of 2.7 MILLION pounds. Nora was named in honor of Nora Stanton Blatch Deforest Barney, a noted suffragist and the first woman in the United States to earn a college degree in civil engineering.
