  • 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.

  • 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.

  • 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.

  • 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.

  • 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 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Burnside Bridge (1926) comprises a double-leaf bascule drawbridge main span, flanked by longer riveted double-intersection Warren deck truss approach spans. The bridge has long multi-beam steel deck girder approach spans bridging railroad tracks, freeways and city streets of downtown Portland, while the main span bridges a fetch of the Willamette River navigable to full-size commercial shipping. This bridge replaced the original 1894 wrought iron truss steam-powered swing-span bridge, two spans of which were repurposed as the current Bull Run River Bridge and Sandy River Bridge on Lusted Road, both in neighboring Clackamas County. Striking features of this bridge are its riveted double-intersection (lattice) Warren trusses featuring intermediate sub-verticals – an uncommon truss configuration, and its ornate bridge operator’s houses. The bridge was designed by Gustav Lindenthal and Joseph Strauss. Other notable features are its hidden below-deck counterweights, ornamental concrete balustrade railings, and fine metal railings on the lift spans. This bridge has great historical significance.

  • 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.

  • 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.

  • 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.
