Built in 1916–1918 and so named for the Scottish immigrant, local settler, and Skagit County Commissioner who promoted its construction. The naming occurred after Henry Thompson was killed by a logging train in 1918.<ref name="Baker River Bridge HAER No. WA-105">{{cite web|url=https://tile.loc.gov/storage-services/master/pnp/habshaer/wa/wa0400/wa0461/data/wa0461data.pdf |title=Baker River Bridge HAER No. WA-105 |publisher=tile.loc.gov |date=August 1993 |access-date=June 7, 2024 }}</ref> At the time, its graceful arch was the longest single-span reinforced concrete bridge in the world<ref>{{cite book |last1=Croft |first1=Catherine |title=Concrete Architecture |date=2004 |publisher=Laurence King Publishing |isbn=978-1-85669-364-6 |page=14 |url=https://books.google.com/books?id=UVRlfzWEnFIC&pg=PA14 |access-date=June 7, 2024 |language=en}}</ref> or perhaps just in the West<ref name="Baker River Bridge HAER No. WA-105"/> and has been listed on the Washington State and National Historic Register since 1976.<ref>[https://www.dahp.wa.gov/gis/pdfs/901.pdf] {{webarchive|url=https://web.archive.org/web/20110723023100/http://www.dahp.wa.gov/gis/pdfs/901.pdf|date=July 23, 2011}}</ref>  Until 1972, when the Washington State Department of Transportation re-routed Highway 20 (then known as Star Route 20) outside the town, the Thompson Bridge was the only connecting thoroughfare across the Baker River and into eastern Skagit County.

The bridge was originally designed by Bowerman and McCloy Consulting Engineers  and built by J.R. Wood Contractors (both of [[Seattle]]).<ref name="Baker River Bridge HAER No. WA-105"/>  It underwent a complete rehabilitation in 2003-2004.  The engineer for the rehabilitation was Entranco, Inc. of [[Bellevue, Washington|Bellevue]] (who has since been acquired by [[AECOM]]) and the contractor for the rehabilitation was One Way Construction of [[Sedro-Woolley, Washington|Sedro-Woolley]].
