Stone v. Southern Illinois & Missouri Bridge Co.

Background

A railway bridge company organized in Illinois got a federal law and War Department approval to build a railroad bridge across the Mississippi River. The company filed in a Missouri court to take 20.3 acres of land for approaches, tracks, and terminal yards so the bridge could connect with rail lines. A Missouri trial court rejected the taking, but the Missouri Supreme Court reversed, ordered damages, and upheld the company’s right to the land. The question came to the U.S. Supreme Court on the claim that federal approval of bridge plans limited state authority.

Reasoning

The central question was whether Congress’s requirement that bridge plans be approved to protect navigation forbade the State from allowing additional approaches and land takings needed to use the bridge. The Court explained that the federal approval power exists to prevent obstructions to navigation, not to make bridges useless by barring necessary connections. Because the approved plans were not altered and the additional approaches served to make the bridge usable, the Court found no federal right harmed and no conflict with the congressional scheme. The Supreme Court therefore affirmed the Missouri decision.

Real world impact

The ruling lets states authorize the extra land, tracks, and terminals that make federally approved bridges practical, as long as navigation remains protected. It keeps the War Department’s role focused on preventing navigation hazards, while leaving to states the power to allow necessary connections and right-of-way takings under their laws. This decision affirms the state court outcome and does not change the federal requirement to protect navigation.
