Curved Steel Trail Bridge at Barbara Walker Crossing on the Wildwood Trail

Albina recently had the pleasure of teaming up with Ed Carpenter and his team to help create the Barbara Walker Crossing Wildwood Trail Bridge at West Burnside in Portland, Oregon. The bridge is 178’ long measured at the center of its curving deck. Its basic structure is a tri-chord truss of rusting and painted steel, Carpenter’s design evokes imagery of the sword ferns and vine maples lining the entire length of the Wildwood Trail This is a project of the Portland Parks Foundation in partnership with Portland Parks & Recreation (PP&R), Portland Bureau of Transportation (PBOT), and Metro. Albina bent 3½” SCH80 A847 and 5″ SCH40 A847 all rolled to various radii, as well as 1″ SCH40 A53B, 1½” SCH40 A53B, 1½” SCH80 A53B all rolled to various radii. Bridge Design and Photos by Ed Carpenter.

Updated Pictures of Basher Pedestrian Bridge at the San Diego Zoo

The August Issue of Modern Steel featured an article titled “What’s Cool In Steel” and one project highlighted was the Basher Pedestrian Bridge at the San Diego Zoo (pages 23-26). Albina Co., Inc. was the bender/roller on this project. Materials rolled for this project included 24 lengths, each measuring 48 feet long, of 16” OD X .0625”  wall tubing rolled to various radii including a 20 foot radius, a 50 foot radius and a 350 foot radius. Check out the pictures below and read the article for more detailed information on the fascinating curved steel bridge.

Signature Curved Steel Sky Bridge at the Phil and Penny Knight Campus for Accelerating Scientific Impact

We took our daughter to tour the University of Oregon this week and we were simply in awe of the amazing facilities and buildings on campus! Our tour started on Franklin Boulevard where the University broke ground in early March on the Phil and Penny Knight Campus for Accelerating Scientific Impact. Albina Co., Inc. bent 22″ OD x 1″ Wall Carbon Steel Pipe to a 105 foot center-line radius for a signature sky bridge that spans Franklin Boulevard and serves as a connector between campus and other U of O research facilities. The $225 million, 160,000-square-foot first phase is slated to open in early 2020.

Albina Featured as the Bender/Roller on Two “What’s Cool In Steel” Projects in the August Issue of Modern Steel

Check out the August Issue of Modern Steel for “What’s Cool In Steel” Albina was the bender/roller on two of the featured projects including the Basher Pedestrian Bridge at the San Diego Zoo (pages 23-26) and a Des Moines sculpture titled “A Monumental Journey” by artist Kerry James Marshall (pages 30-31). We are working on securing some final install pictures of each of these projects! Stay tuned!

What's Cool In Steel

Curved Steel Sky Bridge & Knight Campus Groundbreaking!

On Friday, March 2nd, almost a year-and-a-half after announcing the Phil and Penny Knight Campus for Accelerating Scientific Impact, the University of Oregon broke ground for the new campus! The project is slated to be complete by 2020. A signature sky bridge over Franklin Boulevard will connect the campus to other U of O research facilities while creating a gateway corridor between Eugene and Springfield. Albina Co. Inc. bent 22″ OD X 1″ WALL CARBON STEEL PIPE to a 105 foot centerline radius for the sky bridge. What an amazing project! Stay tuned for install pictures!

Curved Steel Everywhere you Look in Seattle!

We spent this last weekend in Seattle as we took our son and some friends up to a Mariners game. We had Saturday morning to spend in the city, and everywhere we looked, we stumbled upon projects containing curved steel that we have been a part of! The Jimmy Hendrix Museum, The Spheres and Spiral Staircase at The Spheres, the New Spiral Staircase in the Space Needle, the Canopy at the Seattle Great Wheel, the Dale Chihuly Garden and Glass Museum, the pedestrian bridge at the Museum of Flight, and art projects outside of corporate offices. The list goes on! What a true experience to see Brian showing the kids all of the curved steel projects Albina has done over the years! It was a great teaching moment to explain how the entire process works from the beginning of a project to the end and how all the different players work together to accomplish one final product. We were extremely proud to be the steel bender of choice for these amazing projects in the Pacific Northwest. And stay tuned, there are great things happening in the PNW and many more high profile projects coming up!

“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.

Need Curved Steel for a Bridge Project?

Bridge bending? Yes- we bend steel for anything, even bridges! In fact every month steel is leaving our yard for different steel bridge projects. We recently finished bending steel for two bridge projects located on opposite ends of the United States. The first project shipped to Maine and consisted of 12,000# of HSS (rectangular and square tubing). Sizes ranged from TS 8” x 8” x .375” wall to TS 14” x 14” x .375” wall. The second project located in California (a week later) was for 21,000# of W33 X 118# A992 bent the hard way. We can provide bending needs for east coast and west coast projects!

Spiral Steel Bending for University of Kansas Bridge

Albina really enjoyed seeing some of our valued customers at the NASCC trade show earlier in 2017. After the show Albina was asked to spiral bend some TS 20″ X 4″ X .500″ WALL A500 GR B material! This very difficult material was successfully bent by Albina to a varying pitch over the entire length. This bending project was for the Cambridge North Bridge at the University of Kansas.

This particular customer is located in Kansas. They know, if you want it done right, you call Albina. No matter how far away they are located.

Bridge Drain Elbows Often Required on New and Retrofit Bridge Construction

Not all bridges are designed out of bent steel, however, most bridges DO require bent components. One such component, required on both retrofit or new bridge construction, is what is known as a bridge drain elbow. Albina is bending 6” Sch10 material on a new bending machine with new bend tooling for a Caltrans project. The bridge drain pipes we are supplying are 52 pieces in total that we are bending to a 18” center-line-radius (a 3d bend) at 90°. We are working closely with our customer to meet the tight Caltrans delivery requirements for this project. Stay tuned for some images of this project!
