摘要
In replacing the historic Greenfield Bridge, which links the Pittsburgh neighborhood of Greenfield to Schenley Park, the bridge’s designers were challenged to re-create a landmark structure while minimizing the impacts to the congested interstate running under the bridge. From demolition of the existing bridge to design and erection of the new steel arch, the obstacles were overcome through careful planning, extraordinary community involvement, and innovative design.
