MEMPHIS, Tenn. — One side of the I-40 Hernando DeSoto Bridge will be closed Sunday from 5:30 a.m. to 10:30 a.m.

The westbound lanes of the bridge will be shut down so crews can move the message sign in order to do seismic expansion work.

For the last few years work has been done to make the bridge more stable in the event of an earthquake.

The seismic retrofit is designed to protect this bridge and its approaches in the case of an earthquake of up to 7.7 on the Richter Scale.

The total cost of the project is expected to be about $255 million.

All westbound traffic will use Danny Thomas Boulevard to Crump and cross the Mississippi River on I-55.

Monday, from 7:00 a.m. until 7:00 p.m., the inside east and westbound lanes across the bridge will be closed to remove a barrier rail.

For the next few weeks, there will be traffic shifts on the bridge and wide loads will not be allowed during those times.
