Boston Crossing's Restoration Is a Riveting Job-Literally

摘要

Restoration of the 106-year-old Longfellow Bridge, which spans the Charles River between Boston and Cambridge, evokes Rosie the Riveter's World War Ⅱ era, when hot metal pins connected structural steel on bridges, skyscrapers and ship hulls. A joint venture of J.E White, Skanska and Consigli began work in July 2013 on the $255-million design-build project, scheduled for a November 2016 completion. The goal is to replace structural elements while retaining the aesthetics of the 2,135-ft-long bridge, which has 11 open-spandrel steel-arch spans, plus two steel-girder approach spans at the Cambridge end. With a deck width of 105 ft, it carries trains, vehicles, pedestrians and cyclists. The granite masonry piers support four towers that inspired the nickname "Salt and Pepper" (ENR 6/11/07 p. 16).
