View showing the iron arch bridge built over the Schuylkill River between 1861-1866 after the designs of Strickland Kneass. In the foreground, two boys stand on a rock and overlook the Schuylkill River, while a laborer maneuvers an empty wheelbarrow behind them. The Market Street Permanent Bridge, built from 1798-1806 after the designs of Timothy Palmer and expanded around 1850 to accommodate a connection between the city railroad and the Pennsylvania Railroad, is also visible in the background. The Chestnut Street Bridge, partially funded and utilized by the Chestnut and Walnut Streets Passenger Railway Company, was demolished in 1958.
