Newkirk Monument

The Newkirk Viaduct Monument is a 15-foot white marble obelisk in the West Philadelphia neighborhood of Philadelphia, Pennsylvania. It was installed in 1839 to mark the completion of the Newkirk Viaduct, the first permanent railroad bridge over the Schuylkill River. It is inscribed with the names of 51 railroad builders and executives, among other information.

Designed by Thomas Ustick Walter, a future Architect of the Capitol, the monument was erected by the Philadelphia, Wilmington and Baltimore Railroad to mark its completion of a bridge across the Schuylkill River and the first railroad line south from Philadelphia. The monument originally sat about 700 feet from the riverbank.
