The bridge consists of a contemporary tubular steel arch with a main span approximately 222 feet (68 m) long over Storrow Drive via a 14-foot (4.3 m) wide deck that accommodates both bicyclists and pedestrians. The bridge is 550 feet (170 m) in length and was designed to comply with Americans with Disabilities Act maximum slope requirements, and also to avoid large trees in the parkland while also maximizing views.
The sculptural curves and lightness of the bridge make it appear to float above the parkland and its Y-shaped vertical supports mimic tree branches. Aesthetic lighting complements the narrow-beam pin lights that illuminate the walking path, creating a safe and interesting destination at night. The bridge enhances its historic setting while providing greater access and visibility to all users.[5]
