I-40 Hernando De Soto Bridge Emergency Repairs

Memphis, Tennessee

A critical fracture discovered during a drone inspection on one of the 900-foot horizontal steel beams of the Hernando de Soto bridge jeopardized its integrity and triggered an emergency shutdown over the Mississippi River in May 2021. The 50-year-old bridge connects over 60,000 motorists daily between Memphis, Tennessee and West Memphis, Arkansas via I-40.

Within 72 hours, Kiewit had mobilized teams from across the U.S. to engineer solutions and begin construction to innovatively stabilize, repair, strengthen, and reopen the bridge to traffic only 83 days after the structural crack was first discovered.
