Weekly Jigsaw Puzzle

BNSF Cowlitz River Bridge

BNSF Cowlitz River Bridge

Replacing a century-old railway bridge in rural Washington meant accessing an isolated jobsite and developing a careful construction plan. Choosing steel made both easier!

Structural steel gave the new BNSF bridge longer spans--reducing the number of foundations in the Cowlitz River--and allowed smaller sections to be transported to the site and assembled on location.

Learn more about this bridge replacement project at aisc.org/bnsf-cowlitz-river. Then assemble a view of its scenic location outside of Vader, Wash. at aisc.org/puzzles!
