Burnside Bridge Elevation fron Southeast (Eastbank Esplanade)

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. Multnomah County, Oregon, USA.
