Water Shadows a Concern from Italy to Little Italy

From the Wall Street Journal this morning, about the 142-year effort to build a bridge between Sicily and the Italian mainland:

The late marine explorer Jacques Cousteau helped with research. At one point, a study was commissioned to study the effect of the bridge’s shadow on fish. None was found.

The Observer‘s Eliot Brown had a story in this week’s paper about similar shadowy concerns over floating walkways, heliports and such associated with planned city parks like the Hudson River Park and the Brooklyn Bridge Park. Some people say the walkways over water won’t hurt the marine life below. The state Department of Environmental Conservation thinks otherwise.
