Tunneling 200 Feet Underneath Connecticut For Cleaner Water, At A Cost

A giant, miles-long tunnel is about to be drilled hundreds of feet beneath Connecticut’s capital. This subterranean project will take years, cost hundreds of millions of dollars, and the hope is, result in cleaner water for the Connecticut River and Long Island Sound. The size is impressive. About 200 feet below ground will lie a tunnel, 18 feet in diameter that’s drilled through rock — and extending about four miles.
