Saskatoon Bridge Under Construction 照片檔

Saskatoon, Canada - October 29, 2016: A span of the new Traffic Bridge in Saskatoon is bolted together by construction workers. The original bridge, opened in 1907, became structurally unsound and had to be demolished to make room for a new bridge that will look fairly similar, although the deck will be wider to handle modern traffic. The concrete pillars in the river have been renovated and will be used for the new bridge. The first new span of the bridge is being bolted together on the Nutana side of the river. The new spans are made of weathering steel, or Cor-Ten, which will protect the bridge material while giving a rusted look. Construction workers are busy in several places on the new bridge span assembling the steel beams.
