Keokuk & Hamilton Bridge Co. v. United States

Background

A private bridge company owned an authorized bridge across the Mississippi River that included a pivot pier, a draw, and a downstream protection pier. Later, authorized improvements required deepening the channel on the east side of that protection pier. The United States performed the work, drilling and blasting solid rock beside the pier with dynamite. Blasts and the action of the water loosened parts of the pier, causing some sections to fall into the river. The damage could have been repaired for about $1,000. The company rebuilt the bridge for heavier traffic and sued, claiming the pier was destroyed or effectively taken by the United States.

Reasoning

The Court treated the key question as whether the injury amounted to a government taking that requires compensation. Relying on the trial court’s findings, the Court accepted that the pier was not destroyed but only damaged in a way that could have been repaired for a moderate sum. The Court explained that this was ordinary incidental damage from authorized navigation improvements. If a private person had done the same thing, it might be a tort, but when the United States causes such incidental damage in carrying out navigation work, the Court said there is no remedy against the Government. The judgment for the United States was therefore affirmed.

Real world impact

This ruling means owners of bridges and similar river structures face limited ability to recover money from the federal government for minor, accidental harm caused during authorized river-improvement projects. Property owners may need to repair or rebuild at their own expense unless the injury rises to a compensable taking.
