The steel trestle shown below is a modern structure with a long expected lifetime compared to a wooden trestle. Being fire resistant in this brushy location is also an advantage. The approaches to the Kate Shelley High Bridge are steel trestles.
New Orleans utilizes steel trestles to support parts of I-10, the Pontchartrain Expressway, and Tulane Avenue. Also, trestles support the elevated railroad leading to and from the Huey P. Long Bridge.

Famous quotes containing the word steel:
“The complaint ... about modern steel furniture, modern glass houses, modern red bars and modern streamlined trains and cars is that all these objets modernes, while adequate and amusing in themselves, tend to make the people who use them look dated. It is an honest criticism. The human race has done nothing much about changing its own appearance to conform to the form and texture of its appurtenances.”
—E.B. (Elwyn Brooks)
