The Walnut Street Bridge: The People's Bridge

The pedestrian truss bridge just off the western shore of City Island was, before January twentieth, nineteen ninety-six, a fully functioning highway span crossing the entire Susquehanna. On that morning, after days of warm weather following the North American blizzard of nineteen ninety-six, the river rose fast. An enormous ice floe riding the floodwaters struck the western spans of the bridge. The force of it lifted two spans clean off their foundations and swept them downriver. A third span was damaged and later collapsed into the current. The whole sequence was captured on video by someone standing on the bank, and the footage ran on national news that night.

The Phoenix Bridge Company had built the original span in eighteen ninety. It was added to the National Register of Historic Places in nineteen seventy-two, a recognition of its significance as a long-span through-truss bridge in cast iron and steel. After the nineteen ninety-six disaster, a community group called the People's Bridge Coalition formed to advocate for preserving what remained. Rather than demolition, the surviving eastern portion was stabilized and eventually repurposed as a pedestrian and cycling bridge, connecting downtown Harrisburg to City Island.

The bridge today carries walkers, cyclists, and the occasional jogger. Stand at mid-span and look upstream or down, and the Susquehanna fills the frame from bank to bank, a river nearly a mile wide at this point, wide enough that the original crossing was one of the engineering challenges of the nineteenth century. The ice floe that destroyed part of it was not a freak event. It was simply the river doing what the Susquehanna does: rise without warning and remind everyone which force in this landscape is actually in charge.
