Update on the I-40 Hernando DeSoto Bridge Repairs

MEMPHIS – TheTennessee Department of Transportation (TDOT) and the Arkansas Department of Transportation (ARDOT) are working together to safely repair and reopen the I-40 Bridge over the Mississippi River as soon as possible. After three days of intense and thorough analysis, we have the following information to share.

  • The Department met with our Structural Team, which included TDOT, ARDOT, FHWA, TDOT’s consultant Michael Baker, Inc. (MBI), and ARDOT’s consultant HNTB to go over the details of the bridge modeling.
  • There was a consistent message that, above all, the safety of the public was paramount, and the priority was to 1) open the bridge to river traffic  2) open the bridge to vehicular traffic  3) look at the bridge for long-term issues related to the original failure. 
  • There is no indication that the bridge is continuing to deteriorate. We went through an extensive bridge modeling program to be sure it was safe for river traffic.
  • We are performing additional modeling with different analytical tools to ensure quality control to have a redundant analysis before we make a final determination that the bridge is structurally stable.
  • The US Coast Guard made the decision to reopen the Mississippi River to traffic at 9:00 AM CDT this morning.
  • The design team is investigating the benefits of installing a steel plate to beef up the fractured section and thus increase our factor of safety for the existing configuration.
  • The design team is working on an interim repair design concept that contemplates using steel rods that would be attached to the bridge and span over the fractured section, and provide the needed strength to reopen the bridge to vehicular traffic.
  • The interim repair would allow time for a new bridge component to be fabricated to replace the bridge’s damaged 37’ long section.
  • ARDOT is continuing to monitor the fracture area to ensure that no additional fractures are propagating from the existing section.
  • FHWA has requested that the section of damaged steel be preserved so that a detailed forensic investigation of the plates could be done later.
  • TDOT is working with the University of Memphis to see what could be gained from some of their research activities on the bridge that might have captured some information regarding the fracture.
