Richardson Bridge (1912) is a rare example of a double-intersection Warren through truss design. A Warren truss (or equilateral truss) utilizes equilateral triangles in its truss geometry for ultimate weight-saving efficiency. This bridge has been moved twice, but remaining within Oregon. Originally built in 1912 over the Crooked River in Crook County, it was relocated in 1956 to a crossing of the Siuslaw River in Lane County, and finally, in 1986, relocated to its current location in West Eugene and converted to a pedestrian-bicycle crossing of Amazon Creek for the Fern Ridge Trail. Partial dismantling for the 1956 and 1986 relocations saw the original rivet fasteners being replaced with modern-era high strength bolts. Notable is the absence of upper lateral bracing. Lane County, Oregon, USA.

Earl Blumenauer Bicycle and Pedestrian Bridge (2022), is a tied-arch type bridge design spanning the Interstate 84 freeway in Portland, Oregon, USA. The bridge is aligned with NE 7th Avenue, connecting neighborhoods in Northeast Portland for bicycle and pedestrian users, but not for vehicular traffic. The design does accommodate use by emergency vehicles in the event of some catastrophic or seismic emergency. Previously known during design development as Sullivan’s Crossing, the bridge was dedicated and named for Congressman Earl Blumenauer, advocate for rail and streetcar mass transit, and promoter of commuting by bicycle. Construction was completed in 2022.

To the casual viewer the size and graceful curves in contrast to the color, geometry, and texture of the brick buildings stand out. What seems to be Dacron or another durable sail cloth forms a canopy at the main entrance to the circa 1982 residential facility for Michigan veterans. Whether rain, snow, wind, or hot sun, this awning makes it pleasant for visitors to go from car to entryway and reception desk.
This photo shows some of the hardware and alignment of pieces that form the rigid skeleton supporting the soft cover. Each part of the finished design was calculated, checked multiple times, and probably tested in laboratories before being added to the construction: diameter of main columns, thickness and grade of steels in the columns, connective elements to hinge the outreaching support limbs, the cable dimensions and length to anchor the short end off the overhead arms, the curve of the pieces that space the main columns, characteristics of bolts fitted, and the exact angle to place the columns and all connected pieces. Once you begin to see the architecture in math terms, the many calculations to answer the question about strength, flexibility, durability, and ease of maintenance, not to forget cost for materials and labor --- all these aspects begin to arise.
To see the stages of erecting the frame and then fitting the fabric would be eye-opening. Doubtless a very particular sequence of events was needed to complete the construction safely and thoroughly.

The opening is to be filled with concrete precast segments with use of the blue gantry crane. The other side (North Side) of the bridge is completed. The deck that I was standing on is pretty much completed too, the middle was still empty! Installation of precast segments would take 3 weeks to 2 months each!

In 2003, they got their opportunity when a young fin whale beached on Sunset Beach in Orange County, California. Despite intensive efforts to save the whale, it died. Cranford and Krysl were able to obtain the animal’s head for their research and ran it through an X-ray CT scanner originally designed for rocket motors. The fin whale skull used for their experiment now resides in SDSU’s Museum of Biodiversity.

Engineers at UC San Diego's Englekirk Center tested in May 2008 the seismic response of precast concrete floor systems that are used in parking garages, college dormitories, hotels, stadiums, prisons and increasingly in office buildings. The shake table was recognized with a Best of What's New award by Popular Science in November 2013.
Springfield Main Street Bridge (1929), also called Willamette River Springfield Bridge, is a 3-span continuous Warren through truss bridge over the Willamette River, between Springfield and Eugene. Striking features of this bridge, constructed in 1929, are the graceful arch-shaped curvature of its polygonal top chord geometry, decorative concrete railings and entrance pylon ornamental lights. The bridge was designed by Conde B McCullough, acclaimed bridge engineer and designer of many arched bridges on the Oregon Coast Highway noted for their beauty and innovation. Other notable features: it is one of only three pre-1941 continuous truss designs, and it is the largest non-cantilever truss span in the state. Lane County, Oregon, USA.

As the viaducts of the South Island Line pass through dense urban areas we were asked to design noise barriers along much of the length. With Aedas, Atkins developed an integrated solution that supported the overhead lines supplying power to the trains, allowed hot air and smoke from any fires to vent out and gave views out for the passengers.
Hopefully also it is also interesting to look at from outside. It is difficult to hide a viaduct but we came up with a gradated green tube of glass and metal facets that then shifts colour as it enters the two stations - which each have their own colour.

Booth-Kelly Railroad Bridge (1882), now called Hayden Bridge, is a single span Whipple through truss spanning the McKenzie River in Springfield. A Whipple truss is a (stronger) variation of the Pratt truss, also called a “Double Intersection Pratt”, characterized by diagonal tension members crossing adjacent verticals, thereby spanning two panels instead of just one for the Pratt truss. It is considered the oldest surviving bridge in Oregon, while rare and significant for its wrought iron Phoenix columns. This bridge has been moved once. Originally built in 1882 by Phoenixville Bridge Works at Corrine, Utah, it was dismantled and relocated in 1901 to its current location to serve the since abandoned Weyerhaeuser Logging Railway. The bridge was abandoned in 1987, then decked for pedestrian use and reopened in 2019. Notable also is the use of longitudinal bracing rods beneath the bottom chord bracing the deck beams.

Looks like modern art, but these are actually part of the support network for the Statue of Liberty. These are armature bars, originally made of cast iron they followed the contours of the interior copper of the Statue and function much like ribs in a skeleton. Ranger Dee

Richardson Bridge (1912) is a rare example of a double-intersection Warren through truss design. A Warren truss (or equilateral truss) utilizes equilateral triangles in its truss geometry for ultimate weight-saving efficiency. This bridge has been moved twice, but remaining within Oregon. Originally built in 1912 over the Crooked River in Crook County, it was relocated in 1956 to a crossing of the Siuslaw River in Lane County, and finally, in 1986, relocated to its current location in West Eugene and converted to a pedestrian-bicycle crossing of Amazon Creek for the Fern Ridge Trail. Partial dismantling for the 1956 and 1986 relocations saw the original rivet fasteners being replaced with modern-era high strength bolts. Notable is the absence of upper lateral bracing.

Another view of the main line out of New Orleans. Look at the old timber bridge it has to cross and the cross beams stacked up together to get the elevation. Would like to think this kind of infrastructure wouldn't be allowed on UK railways. Bear in mind this bridge is crossing a spillway which will be subject to flowing and potentially eroding water. 2008
