Vital Memphis bridge shut down after officials find structural crack

The Hernando de Soto Bridge was shut down after a "structural crack" was found, closing all I-40 lanes over Mississippi River to traffic on Tuesday, May 11, 2021.

(CNN)Transportation officials discovered a crack Tuesday in a major artery in American infrastructure, meaning it could be closed for months.

The Hernando de Soto Bridge on Interstate 40 in Memphis, Tennessee, was shut down Tuesday and will be closed for emergency repairs, according to a news release from the Tennessee Department of Transportation (TDOT).
TDOT released photos of the crack that shut down the I-40 Hernando de Soto Bridge.
Tennessee shares responsibility for the bridge with the Arkansas Department of Transportation (ArDOT), which discovered the crack during a routine inspection and immediately shut down the bridge, the release said.
      "For the motoring public's safety, the bridge will be entirely shut down while crews investigate the crack's extent further and then repair the problem, which could take some time," the TDOT release read.
        Detours are in place in Tennessee and Arkansas with traffic being rerouted in both directions to Interstate 55 as an alternate route across the river. It is unknown how long the bridge will be closed. Authorities have also shut down river traffic until further notice.
          Memphis Police block the entrance to the Hernando de Soto bridge after a "structural crack' was found, closing all I-40 lanes over Mississippi River on Tuesday, May 11, 2021.
          With boat traffic closed, there are at least 24 vessels with a total of 346 barges waiting to travel the Lower Mississippi River in either direction, according to Lt. Mark Pipkin of United States Coast Guard Sector Lower Mississippi River.
          The bridge's closure comes as President Joe Biden is trying to push his infrastructure plan through Congress. The plan calls on funding for improvements to roads, bridges, railways and other infrastructure
          The US earned a C- in the American Society of Civil Engineers infrastructure report card, which said an additional $2.6 trillion in funding is required over the next decade.
          More than 50,000 vehicles drive over the bridge each day, according to CNN affiliate WHBQ-TV. TDOT is responsible for repairs and maintenance of the bridge, while ArDOT is responsible for inspections, which happen every two years, the affiliate reported.
            According to CNN affiliate WMC-TV, the bridge is "a vital piece of America's infrastructure for moving traffic and freight around the country."
            It took six years to build the bridge, WMC states, and the governors of Tennessee and Arkansas cut the ribbon in August 1973.
