Holcomb Creek Trestle, Railroad trestle bridge near Helvetia, Oregon, United States.
The wooden railroad trestle spans 1,168 feet across Holcomb Creek, rising 90 feet above the ground with concrete partitions between timber sections.
Built in 1905 by United Railways for the Oregon Electric Railway, the structure represents early 20th-century railroad engineering in the Pacific Northwest.
The trestle reflects Oregon's railroad and logging industries, which shaped the development and economic growth of Washington County throughout the 1900s.
Portland and Western Railroad maintains and operates the trestle, which remains the longest wooden railroad bridge still functioning in the United States.
The bridge incorporates specific fire prevention features through strategically placed concrete barriers that separate different sections of the wooden structure.
