Brooklyn's Answer to High Line:We've Got 'Friends' in Low Places

In June 2008, amid the excitement over the opening of Manhattan's High Line Park, a Brooklyn organization Friends of the Atlantic Tunnel received a $500,000 grant from the Bloomberg administration's OPENYC parks initiative to begin planning an underground park to be built in the long-forgotten Atlantic Avenue Tunnel (aka the world's oldest subway tunnel) which carried passengers to and from the Brooklyn waterfront from 1844 to 1859.

The new park, tentatively dubbed The Low Line, will have a decidedly subterranean theme, with initial concepts for development that include a fungus garden, a bowling alley - where night-vision goggles are rented alongside bowling shoes, and an interactive edutainment exhibit tentatively titled "Exploring Brooklyn's Other Underground Railroad".
