Spider Bridge at Falls of Schuylkill, Suspension bridge at Falls of Schuylkill, Philadelphia, United States.

Spider Bridge at Falls of Schuylkill was a suspension bridge that crossed the Schuylkill River with a narrow walkway supported by iron wire cables and wooden beams. The structure stretched about 407 feet between the banks, connecting the industrial areas on both sides of the river.

Constructed in 1816 by Josiah White and Erskine Hazard, this bridge was the first to use wire cables in suspension bridge design anywhere in the world. It was built to provide a crossing for workers and materials needed by the industrial operations on both riverbanks.

The bridge represented a shift in American engineering methods, transitioning from traditional chain suspension designs to modern wire cable technology.

The narrow walkway required careful footing and was designed primarily for workers moving between industrial sites. The bridge's location made it essential for daily work routes, as it was the main crossing point above the waterfalls on the river.

A British Army officer named Joshua Rowley Watson documented the bridge's construction in 1816 and noted that it could support multiple pedestrians at once, which was remarkable for the time. His detailed observations helped establish confidence in the new wire cable technology.
