  • 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.

  • Mount St Helens ash eruption, 2005, viewed from Portland, Oregon.  As if to signal the 25th anniversary of the devastating 1980 eruption, Mount St. Helens released this symbolic outpouring of ash and steam at 17:30 on Tuesday evening, March 8, 2005.  Volcanic ash rose to 36,000 feet and fell as far away as 125 miles east of the mountain. The eruption began with practically no warning, an hour after a magnitude 2.0 earthquake on the volcano's east side, and lasted 30 minutes.  Mount St. Helens, a 8,364-foot (2550m) volcano, is located about 40 miles (60km) northeast of Vancouver, Washington, Portland's sister city across the Columbia River which divides the states of Oregon and Washington.  The river in the photograph is the Willamette River, which divides Portland's east and west sides.  The Columbia River is not visible in this image; it runs perpendicular to the Willamette.  Mount St. Helens was named for British diplomat Alleyne Fitzherbert whose title was Baron St. Helens.  The mountain was named by Commander George Vancouver and the officers of H.M.S. Discovery while exploring the northern Pacific coast from 1792 to 1794.  Mount St. Helens erupted violently at 08:32 on Sunday, May 18, 1980.  Nikon F4S, 70-300/4-5.6D. Fuji RVP100F..

  • Bust of York, Mount Tabor Park, Portland, Oregon, USA.

The statue of Harvey W Scott was found toppled to the ground on the morning of 20 October 2020 following a series of statue removals during racial justice protests in Portland. Inscription reads: “York – The first African American to cross North America and reach the Pacific Coast.  Born into slavery in the 1770s to the family of William Clark, York became a member of the 1804 Lewis and Clark Expedition. Tough York was an enslaved laborer, he performed all the duties of a full member of the expedition. He was a skilled hunter, negotiated trade with Native American communities, and tended to the sick. Upon his return east with the Corps of Discovery, York asked for his freedom. Clark refused his request.  The date and circumstances of his death are unclear."

  • 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. Broward County, Florida, USA.

  • 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.

Born into slavery in the 1770s to the family of William Clark, York became a member of the 1804 Lewis and Clark Expedition. Tough York was an enslaved laborer, he performed all the duties of a full member of the expedition. He was a skilled hunter, negotiated trade with Native American communities, and tended to the sick. Upon his return east with the Corps of Discovery, York asked for his freedom. Clark refused his request.  The date and circumstances of his death are unclear."

  • 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.

  • 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.

  • 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.

  • 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. 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.

  • Ferry Street Bridge (1950), also called Coburg Road Bridge for the road that it carries, is a two-span continuous Warren through truss steel bridge, with polygonal top chord, spanning the Willamette River. It is located near downtown Eugene, where the city’s founder Eugene Skinner once operated a ferry service. The bridge has long multi-beam concrete approach spans, accounting for the flood plain and floodway corresponding to the river hydrology. The bridge was constructed in 1950 – replacing its predecessor from 1876 – and was extensively rehabilitated in 1999 by Mowat Construction Company. Notable features are its mid-span pier (mid river), supporting a continuous truss, ornamental lighting, and separated pedestrian/bicycle walkways on both sides, supported by curved cantilever sidewalk brackets. Lane County, Oregon, USA.
