Why are all train bridges called trestles and not just bridges? On the other hand, why are motor vehicle bridges that have the characteristics of a trestle, considered a bridge? Example: Dames Point Bridge in Jacksonville Florida. Parts of the bridge have a horizontal beam that is supported by a pair of sloping legs. Yet, it is considered a cable-stayed bridge. Does it have to be wooden to be considered a trestle as well? Are there motor vehicle bridges that are trestles still in use today?

they’re all bridges, the prefix typically just describes the support structure. Honestly just google the different types of bridges and you’ll have your answer

“A trestle (sometimes tressel) is a rigid frame used as a support, historically a tripod used both as stools and to support tables at banquets. A trestle bridge is a bridge composed of a number of short spans supported by such frames.

“Timber and iron trestles (i.e. bridges) were extensively used in the 19th century…

“Many timber trestles were built in the 19th and early 20th centuries with the expectation that they would be temporary.”
