There could be delays of several minutes at either end of the bridge, as traffic is allowed to progress from the other side.
Affected drivers may detour on Highway 51 through Cairo to Highway 3 and the I-57 interchange, then take I-57 south to Missouri.
Earlier this week, the bridge was closed during the day. The closure was needed for crews to perform a required safety inspection of the structure.
