Presentation:

The Unwanted Discovery on the Hernando de Soto bridge

Details:

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.


Speaker:

Ted Kniazewycz, PE, Tennessee Department of Transportation; Structures Division Director.

Ted is the Structures Division Director for the Tennessee Department of Transportation where he has inspection and maintenance responsibilities for over 8,000 state-maintained bridges and inspection responsibilities for another 12,000 locally owned structures. He was the Point of Accountability for the Hernando de Soto Bridge Emergency Repairs. In addition to these responsibilities, Ted is actively involved in AASHTO Bridge Committees on Structural Steel, Construction and Research. Ted received his Bachelor of Science degree in Civil Engineering from Tennessee Technological University and is a licensed engineer. He began his career with TDOT in 1985 where he worked for seven years before becoming Metro Nashville’s first Bridge Engineer. After establishing their bridge program, he went into consulting before returning to TDOT as the Director in 2017.
