STV provided engineering design services to the WSC-Joint Venture of J.F. White Contracting Co., Skanska, and Consigli Construction Co. for a new pedestrian bridge, the Frances "Fanny" Appleton Pedestrian Bridge, named for Henry Wadsworth Longfellow’s wife.  Located on the Boston side of the Charles River, it crosses over Storrow Drive and connects to the Charles River Esplanade, a popular park that hosts the world-renowned Boston Pops Fireworks Spectacular every July 4th. It replaced a nondescript and inadequate pedestrian bridge.

The curvilinear, ribbon-like steel bridge consists of 550 feet of continuous girders supported by a signature tubular arch span that gracefully branches to a scenic overlook plaza and curved stairs. With no center piers, it appears to float over Storrow Drive.  STV’s work addressed fabrication, constructability and pedestrian-induced vibration performance. The firm worked closely with the design-build team to include cost-effective design modifications, to meet the architectural objectives and to improve constructability and the user experience.
