Nora Takes Shape Underground in Newburgh

Nora is one of the world’s most advanced tunnel boring machines (TBM) and she is being assembled 854 feet below ground in Newburgh, NY. The entire machine — including its cutter head, body and trailing gear — will be more than 470 feet long and weigh upwards of 2.7 million pounds. Its cutter head (pictured above) is 21.6 feet in diameter. The TBM is an integral part of DEP’s $1 billion project to repair the 85-mile Delaware Aqueduct, the longest tunnel in the world.
