Two years later he joined the Union Construction Company, where he gained experience in building incline planes and railroads.

Then a year later he decided to join the Swiss National Railroad, where he was hired on as a division engineer in charge of location and construction.

When he first arrived in the United States he was employed as a journeyman stonemason for the memorial granite building of the Centennial International Exhibition in Philadelphia in 1876.

The PRR hired Lindenthal in 1904 to work on the New York Connecting Railroad and lead the Hell Gate Bridge project.

[1]: 297 Lindenthal's career transitioned to public service when he was appointed to lead the New York City Department of Bridges from 1902 through 1903.

[6] While the proposals ultimately remained unbuilt, the city would eventually host a similar (albeit scaled-down) concept sixty years later with the Ford Motor Company "Magic Skyway" attraction at the 1964 New York World's Fair.

Trains being as heavy as they were made engineers greatly overcompensate and build bridges that were oversized, bulky, and expensive.

During the time Lindenthal practiced engineering, the railroad industry was expanding and replacing many wooden-truss bridges with stronger ones capable of handling the heavier locomotive loads.

The steel work was supported with the use of cables during construction to carry the load of the arches until they finally met at the center of the span.

This bridge, completed in 1883 using the structural form of a lenticular truss, could withstand higher stresses, as well as using resources that made it more economical (Approximately $23,000 was saved simply by using these materials).

"[2] At the age of eighty-five, Lindenthal succumbed to a long illness and died shortly after, at his home in Metuchen, New Jersey.

[4] Lindenthal's Metuchen property extended northward towards Oak Tree Road into Raritan Township (present-day Edison, New Jersey), and was later bought by contractor Frank P. Tufaro for the development of the Stephenville community.
