Armitage Bridge (1887), also called Coburg Railroad Bridge and McKenzie River Railroad Bridge (historically, John Day Railroad Bridge), is a single span Whipple through truss bridge over the McKenzie River, between Eugene and Coburg. This bridge has been moved once. Originally erected in 1887 across the John Day River at the confluence with the Columbia River, it was dismantled and relocated here in 1907 by the American Bridge Company for new owners, Southern Pacific Railroad. This bridge was designed by prominent American civil engineer and great bridge engineer, George S. Morison, who designed many major bridges, some of similar configuration to this one. The bridge is made of wrought iron, pin-connected, and riveted throughout, making it one of the few remaining bridges of its era. Further, while this bridge was a relatively small project for Morison, it remains one of the few surviving Morison bridges of this distinctive configuration. Notable features are the deep lattice portal bracing, mid-height horizontal beam in the end panels and cast-iron decorative details, like the date plate. Lane County, Oregon, USA.

The tallest tower in the entire Japan now is Skytree, reaching 634 metres, which is the second tallest structure in the world after the Burj Khalifa.
This is the Skytree itself, observed through the glass floor they have at the very limited area. It's very cool to see how the tree is bending to support its weight!

Snow-Reed Bridge (1925) is the oldest bridge in Fort Lauderdale, and the last operational swing span bridge surviving in South Florida. In 1989, 64 years after construction, it was designated a historic landmark and renamed from the Southwest 11th Avenue Bridge to Snow-Reed Bridge, for the two mayors whose terms spanned its 1924-5 construction. The bridge spans the North Fork of the New River and was constructed on the north-south alignment of SW 11th Avenue, connecting the neighborhoods of Riverside and Sailboat Bend. The structure is a Warren Pony Swing Metal Truss – the Pony part being simply a through truss that lacks overhead cross-bracing between the top chords. Nice cantilevered sidewalks appear to have been added at some point. The bridge has no practical vertical clearance, while it obstructs a navigable river, so an on-site bridge operator is required 24/7. A one-year major renovation ending in 2010 added a new octagonal-shaped bridge tender control house while retaining and restoring the original bridge tender’s house. Notable also is this old bridge’s vulnerability to sea-level rise; its swing mechanics are set just inches above sea water tide levels, so the mechanics are repeatedly submerged in salt water. Builder: Champion Bridge Company, Wilmington, Ohio. Broward County, Florida, USA.
Clay Shaw Bridge (2001), also called the 17th Street Causeway Bridge, is a pair of twin parallel 54-foot-wide causeway structures, each incorporating a double-leaf bascule bridge, separated by a 13-foot open air median. This new bridge, spanning 210 feet between trunnions, increases navigable waterway width of the Intracoastal Waterway from 100 feet to 125 feet, and vertical clearance from 22 feet to 55 feet, over the previous 1956 bridge at this location – the Commodore Brook Memorial Causeway. Striking features of this bridge are its V-shaped Carina piers (providing excellent visibility for shipping navigation) and the Art Deco-style bridge operator’s house. Also notable are the open traffic railings (for greater vista visibility), emergency shoulders, bicycle lanes and sidewalks – with pedestrian overlooks incorporated into the bascule spans. Owner: Florida Department of Transport; Design consultant for piers and bascule bridge: EC Driver & Associates; Design of Bridge Structures: FIGG Bridge Engineers; Roadway: Keith & Schnars. Fort Lauderdale, Broward County, Florida, USA. Nikon PC-Nikkor 28mm f/3.5 at f/11.
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.

Peter DeFazio Bridge (1999) is a pedestrian and bicycle suspension bridge across the Willamette River in Eugene. Its eye-catching form displays interesting and unique architecture, with a modernist take on the classic suspension bridge. The DeFazio Bridge is celebrated for providing transportation and recreation opportunities that are in harmony with the natural environment, conveniently connecting several multi-use pathways and serving as primary bicycle-pedestrian artery between downtown Eugene and neighborhoods north of the river. Gradual grades on main span, approach ramps and stairs make this bridge the functional equivalent of the ultimate freeway spaghetti-interchange for pedestrians and bicyclists, yet its artful architecture compliments the beautiful urban park setting of Alton Baker Park. The DeFazio Bridge enhances accessibility to, and use of, the park – a marvel of modern bridge engineering. The bridge was designed by Jiri Strasky of Strasky Husty and Partners, and OBEC Consulting Engineers, built by Mowat Construction Company, and named after the Oregon Congressman. Lane County, Oregon, USA.
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.

Springfield Railroad Bridge (1911), also called Union Pacific Springfield Railroad Bridge for the line that it carries, is a traditional railroad through truss bridge over the Willamette River, between Springfield and Eugene. The design is comprised of a Pratt truss secondary span (left) and a Parker truss main span (right), with trestle approach spans (not visible). A Parker truss is a variation of the older flat-topped Pratt truss; note how the taller Parker truss is essentially a Pratt truss (left) with a polygonal top chord. Originally built in 1911, it is reported that the main span (Parker truss) was strengthened extensively in 1925. Notable features are the riveted construction and pin-connected framing.

The John F. Kennedy Memorial Bridge is a seven-lane, single-deck cantilever bridge that carries Interstate 65 across the Ohio River, connecting Louisville, Kentucky and Jeffersonville, Indiana. The main span is 700 feet (two spans) and the bridge has a total length of 2,498 feet. Construction on the bridge began in the spring of 1961 and was completed in late 1963 at a cost of $10 million. The span had yet to be named when U.S. President John F. Kennedy was assassinated on November 22, 1963. Four days later, Kentucky Governor Bert T. Combs announced that there was wide agreement that the bridge would be named in Kennedy's honor.
In the background, you can also see the George Rogers Clark Memorial Bridge. It is a cantilevered through truss bridge on US 31.

The Cumberland River Bridge (also called the Veterans Memorial Bridge) as it crosses Old Hickory Lake just south of Gallatin, Tennessee can be seen on the far right of this photo. It is a steel through truss bridge that was built in 1954 and is currently on the 'Structurally Deficient" list due to the 'poor' rating on it's superstructure. What you see in the rest of this photo is its replacement. It is a new Structural Steel/Precast Bulb-Tee Bridge designed by ICA Engineering. The new bridge is 1890 ft in length and has approximately 3500 ft of roadway widened from 2 lanes to 4 lanes with curb/gutter and sidewalk. As a Structural Engineer, this was a photograph that was just too interesting to pass up!!
Three bracketed photos were taken and combined with Photomatix to create this HDR image. Additional adjustments were made in Photoshop CS5.

Soaring across the Douro River, the Ponte de Dom Luís I remains Porto’s most recognizable landmark — a double-deck iron bridge designed by engineer Téophile Seyrig, a disciple of Gustave Eiffel. Completed in 1886, it connects Porto’s Ribeira district with Vila Nova de Gaia, where the famous port wine cellars line the opposite bank. The elegant parabolic arch spans 172 meters, once the longest of its kind, and is still celebrated as a feat of 19th-century engineering. From this vantage, the upper deck carries trams and pedestrians high above the river, offering panoramic views over Ribeira’s colorful waterfront and the tiled rooftops cascading down the hillside. The lower deck brings everyday traffic closer to the water. Together, bridge and city form a living postcard of northern Portugal — equal parts historic charm and enduring innovation.
The Crystal Palace was the largest glass and iron structure built up to that point in history, and it was a significant achievement in structural engineering. Originally erected in Hyde Park, London, for the Great Exhibition of 1851, it was a groundbreaking structure made from cast iron and plate glass.
The Crystal Palace was enormous, spanning 1,851 feet in length and 128 feet in height, and it housed a 990,000-square-foot exhibition space. It was a pioneering example of using prefabricated cast iron and glass, which were relatively new materials at the time. Despite its size, the Crystal Palace was completed in a remarkably short period of 39 weeks using modular construction techniques.
The Crystal Palace demonstrated the potential of industrial-age materials and construction methods, influencing the design of future large-scale structures. It became a symbol of the Victorian era and British Empire's technological prowess. While the Crystal Palace was later moved and eventually destroyed by fire in 1936, its legacy as a groundbreaking glass and iron structure remains.

FEC New River Bridge (1978) is a single-leaf bascule railroad bridge spanning the navigable New River in downtown Fort Lauderdale. The design type is a through plate girder bridge of total span 70 feet /21.3m, providing a horizontal boat navigable clearance of 60 feet/18.3m. Additionally, the bridge comprises three 25-foot approach spans, plus a 14-foot machinery room span, from the north; and two 25-foot spans from the south. Notable was the use of weathering steel to eliminate environmental concerns around initial and future painting. By 1985, the weathering steel had reportedly reached a stable condition for its environment. One of the design criteria for this bridge was to double-track the crossing, removing the bottleneck of a single track bridge at this location dating back to 1912. Now, in the 21st Century, as freight trains are once again sharing the tracks with passenger trains operated by Brightline, alternatives are being studied through the New River Crossing Feasibility Study to further expand capacity by tunnel and various fixed/movable bridge replacement options.

The San Francisco–Oakland Bay Bridge stretches gracefully across the bay, linking the city to the East Bay with muscular poise and engineered elegance. Completed in 1936, the bridge features a double-deck design and is composed of two major spans—this view highlights the western span with its cantilever and suspension elements. The structure’s steel latticework stands bold against the blue sky, its vertical cables forming a rhythmic pattern. Treasure Island sits just beyond the tower, and the container cranes of Oakland peek through the mist. It’s a portrait of California infrastructure at its most iconic: purposeful, enduring, and framed by natural beauty.

Rising elegantly above San Francisco’s Financial District, the Transamerica Pyramid is an architectural icon that defines the city’s skyline. Completed in 1972 and designed by William Pereira, this 853-foot tall structure was initially met with skepticism due to its unconventional shape, but it quickly became one of San Francisco's most beloved landmarks. The building’s unique pyramid shape was conceived to maximize sunlight on the surrounding streets, a thoughtful touch that sets it apart from the typical high-rises of the era. The exterior is clad in crushed quartz, giving it a shimmering, light-reflective quality that changes with the time of day. The Transamerica Pyramid’s tapering design and innovative engineering have earned it a place in the pantheon of modern architectural masterpieces. Beyond its striking appearance, the building is also a marvel of efficiency and foresight, designed to withstand earthquakes and other seismic activity, which is essential in this region. Today, it stands as a symbol of the city's forward-thinking spirit, blending form and function seamlessly. Visitors to the area can explore the plaza at its base, which offers a serene contrast to the bustling streets of the Financial District, and snap photos of this futuristic structure from various angles. For those interested in San Francisco’s architectural heritage, the Transamerica Pyramid is an absolute must-see, offering a glimpse into the city’s dynamic blend of innovation and tradition.
