MEMPHIS, Tenn. — Lanes on the I-55 bridge across the Mississippi river were closed Monday due to an overturned tractor trailer, according to iDrive Arkansas.

The trailer, which was transporting cars, tipped over on I-55 in Crittenden County heading into Memphis, blocking all lanes of the ramp.

Southbound lanes have been closed since around 10:30 a.m. Drivers were being detoured to the I-40 bridge.

The state reported the bridge back open later in the day.
