SPIRALING TRUSS HIGHLIGHTS NEW SUBWAY STATION IN BOSTON

A unique spiraling steel truss with a three-dimensional design will be the signature feature of a 21,000 sq ft (1,950 sq m) subway station being built near Boston's Logan Airport. The 260 ft (79 m) truss will dominate the transitional space between the train platform on the Blue Line of the Metropolitan Boston Transit Authority and the bus stops outside. The unusual design is an attempt to provide a stunning visual element for airport travelers using the subway as well as for passersby on three Central Artery elevated roadways around the station. The spine of the complex lattice truss, which curves both vertically and horizontally, will be supported on three towers to create two equal spans of 100 ft (30 m) and an additional 32 ft (10 m) cantilever on both ends.
