According to an ARDOT spokesperson, the bridge is closed because of a “structural infrastructure crack” in the bridge.

The spokesperson added that he will not know how long the bridge will be closed until the inspectors can see the damage.

Officials are currently meeting to find out how much the bridge is damaged and the timeframe for repairs.

ARDOT and TDOT are working together to make sure the bridge is safe before traffic is reopened.

The Hernando DeSoto Bridge was constructed in 1972. It cost $57 million, which is about $335 million today.

Alternate routes:

Arkansas I-40 eastbound traffic should take Exit 5 to Interstate 55 to cross the Mississippi River into Memphis.

Tennessee I-40 westbound traffic should take the I-55 Bridge across the Mississippi River to cross into Arkansas and then take Exit 4 to access I-40 westbound.
