The bridge is constructed of two Шаблон:Convert diameter high-strength steel pipes, bent into twin arches that rise Шаблон:Convert above grade, and suspend the deck by way of 44 stainless-steel hangers, each Шаблон:Convert in diameter. The foundation consists of concrete-filled caissons which go down Шаблон:Convert below grade to the bedrock.

Designed in 1994 by Montgomery Sisam Architects of Toronto and Delcan Corporation (bridge engineers), it was constructed by Sonterlan Construction, and is the recipient of numerous local architectural, design and engineering awards. The bridge is situated at the mouth of the Humber River, the start of the "Toronto Carrying Place" trail, an ancient aboriginal trading route leading north, and thus features design elements and decorations such as carved turtles and canoes that evoke this native heritage.

The bridge forms an important pedestrian, recreational and commuter cyclist link, and carries the Waterfront Trail, a multi-use pathway that will eventually parallel the entire north shore of Lake Ontario. The Toronto section is known as the Martin Goodman Trail, and is one of the most popular pedestrian and cycling routes in the city.
