Maine Replacement Span Sparks Design Controversy

摘要

Foundation work has begun on a new Waldo-Hancock bridge over Maine's Penobscot River. The $65-million single-plane, cable-stayed concrete segmental structure will incorporate an observatory deck in one of two pylons to view nearby historic Fort Knox. But steel proponents think the design choice is too costly and are lobbying for language in the new federal transportation" bill to require dual design alternatives on major structures.
