The Kansas bank of Kansas City carried as much heavy industry as the Missouri side — and in places more of it. Wyandotte County held the Fairfax industrial district and the Armourdale bottoms: the auto assembly works, the packing houses, the refineries and the rail that fed them. Johnson County to the south grew from farm-belt towns into a sprawl of manufacturing and, later, corporate campuses. Across both, twentieth-century operations reportedly ran on asbestos insulation, gaskets, and refractory, and the trades who worked them may have been exposed for full careers.

Two things make the Kansas side its own case. The venue is a Kansas district court — Wyandotte’s Twenty-Ninth Judicial District or Johnson’s Tenth — not a Missouri circuit. And the deadline is far shorter: Kansas allows only two years from a mesothelioma diagnosis to file, against Missouri’s five just across the line. Two workers in the same metro, even the same industry, can face very different clocks depending on which bank they worked. Choose your county below.
