“Meandering River Bridges” with Curved Steel Structures Highlight Phase 1 of the Newberg/Dundee Bypass in Oregon

Phase 1 of the Newberg/Dundee Bypass road in Oregon includes more than ten bridge structures, where the bypass crosses over creeks, wetlands, railroads, or travels over or under other local roads. The Corridor Theme is “Meandering River and Rolling Hills.” The theme includes an open form for bridge structures, which allows views for drivers under the structure and provides opportunities for smooth transitions into the surroundings. A “meandering river” concrete relief is stamped into the concrete railing and an ornamental “rolling hills” design is used where screening is required. That is where we come in! We rolled various tube steel to create the “rolling hills” on the bridges. We rolled:

16 lengths of tube steel 10″ X 4″ X .375″ WALL A500 GR B (30 pcs total) bent the hard way to 15 different radii from 9 ft to 158 ft.
9 lengths of tube steel 12″ X 8″ X .375″ WALL A500 GR B (16 pcs total) bent the hard way to 5 different radii from 28 ft to 58 ft.
19 lengths of tube steel 3″ X 3″ X .313″ WALL A500 GR B (56 pcs total) to 26 different radii from 5 ft to 200 ft.
