The Humber Bay Arch Bridge (also known as the Humber River Arch Bridge, the Humber River Pedestrian Bridge, or the Gateway Bridge) is a pedestrian and bicycle through arch bridge south of Lake Shore Boulevard West in Toronto, Canada. Completed in the mid-1990s, the bridge is part of the Martin Goodman Trail and is in length, with a clear span of over the mouth of the Humber River to protect the environmental integrity of the waterway. ==Design== The bridge is constructed of two diameter high-strength steel pipes, bent into twin arches that rise above grade, and suspend the deck by way of 44 stainless-steel hangers, each in diameter. The foundation consists of concrete-filled caissons which go down below grade to the bedrock.〔 Designed in 1994 by Montgomery Sisam Architects of Toronto and Delcan Corporation (bridge engineers), it was constructed by Soncin Construction, and is the recipient of numerous local architectural, design and engineering awards. The bridge connects the former municipalities of "Old Toronto" and Etobicoke (both now part of the amalgamated City of Toronto) along an ancient aboriginal trading route along the shore of Lake Ontario, 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Humber Bay Arch Bridge」の詳細全文を読む スポンサード リンク
