The Little Thompson River Bridge, in Weld County, Colorado near Berthoud, Colorado, was built in 1938. It was listed on the National Register of Historic Places in 2002.[1]

It was designed by the Colorado Department of Highways, fabricated by Midwest Steel & Iron Works, and installed by contractor Gardner Brothers. The highways department specified "a rigid-connected camelback pony truss, supported by reinforced concrete abutments with angled wingwalls."[2]

The bridge was altered by addition of flex beam guardrails around 1980.[2]

It is located on what is now a service road for Interstate 25, at milepost 249.90, near Berthoud. It is the eastern-most of three north–south bridges at the site; the other two carry southbound and northbound Interstate 25 traffic.[2]

In May 2021, there is ongoing construction at I-25's Little Thompson River crossing, covered in Colorado Department of Transportation photos.[3]
