The Unwanted Discovery on the Hernando de Soto bridge
The 3.3-mile long I-40 Hernando deSoto Bridge crossing the Mississippi River was closed May 11, 2021 after inspectors performing a routine inspection identified a partial fracture in a tension member that supports one of two tied-arch truss spans. The fracture occurred at a welded plate transition in the upstream (north), box-shaped tension tie member (Figure 1). The six-lane bridge was subsequently closed to traffic.
