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:
“We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventions—telephones, electricity, steel bridges, horseless vehicles—they are all leading somewhere. It’s up to us to be on the inside in the forefront of progress.”
—John Dos Passos (1896–1970)
