With all of the subterranean construction planned for the region, tunnel boring machines could one day become part of the lexicon of the average straphanger. These three-hundred-feet-long monsters that eat dirt, stone and bedrock will be used to dig the Second Avenue Subway. MTA officials say the subterranean diggers will less disruptive to life above ground. The boring machine for the Second Avenue subway won't be here for months, but a similar machine used to dig the East Side Access tunnel should be here by next month. "It's being shipped as we speak," said Mysore L. Nagaraja, the MTA's capital construction chief.
The technology is really cool. There's a pretty interesting YouTube video about it. Seriously, this is one heck of machine.
