Details

On May 11, 2021, a partial fracture was discovered on one of the two tie girders on the Hernando de Soto Bridge. This four lane, 900 foot main span bridge carries traffic across the Mississippi River between Memphis, Tennessee and West Memphis, Arkansas. This finding required an immediate river and road closure. TRB will host a webinar on Thursday, November 10, 2022 from 12:00 PM to 1:30 PM Eastern that will share the response to this event, which included a special inspection, analysis, development of analytical models, and repair plans. Presenters will discuss the Federal Highway Administration (FHWA) directives regarding the inspection and testing of butt welds fabricated from AASHTO M244 Grade 100 steel, more commonly known as “T-1” steel. Presenters will also discuss recommendations for addressing the FHWA directive testing requirements.

This webinar is sponsored by the TRB Standing Technical Committee on Steel Bridges.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100.
