Published at 3:07pm ET: NEW YORK - Sixteen stories below Grand Central Terminal, an army of workers is blasting through bedrock to create a new commuter rail concourse with more floor space than New Orleans' Superdome, just one of three audacious projects going on beneath New York City's streets to expand what's already the nation's biggest mass transit system.
But even with blasting and machinery grinding through the rock day and night, most New Yorkers are blithely unaware of the construction or the eerie underworld that includes a massive, eight-story cavern, miles of tunnels and watery, gravel-filled pits.
