The Waddell "A" Truss Bridge, also known as Linn Branch Creek Bridge, is a historic truss bridge located at Parkville, Platte County, Missouri. It was built in 1898. It was designed by engineer John Alexander Low Waddell and is the subject of a U.S. patent, U.S. Patent 529,220.

Waddell went on to become a distinguished engineer of many lift-type bridges (which this is not).
The Waddell "A" Truss Bridge spanned the Linn Branch Creek, in Missouri, but was removed for the construction of Smithville Lake.

The bridge served rail traffic until 1939, and then road traffic for Missouri Hwy 4 from 1953-1980. It was dismantled in 1981 and moved to its current location at English Landing Park in Parkville, MO, in 1987. It was listed on the National Register of Historic Places in 1990.

A second Waddell "A" Truss bridge spans the Cross Bayou in Shreveport, Louisiana. Now abandoned, the bridge once carried the Kansas City Southern Railway across the bayou. It has been listed on the National Register as Kansas City Southern Railroad Bridge, Cross Bayou and is recognized as a historic site by the City of Shreveport.
