MoDOT officials say that one lane is open on the Champ Clark Bridge at Louisiana, Missouri.
As of 8:20 a.m., the lane was open on the Illinois approach to the bridge.
Officials say that the other lane should open as soon as the water goes down.
Flooding forced the bridge closure Sunday, July 6.
At this time, it is unknown if weekend rains to the north could force another closure of both lanes.
