Starting June 1, 2015, repair work will affect traffic on the Centennial Bridge between Rock Island, Illinois and Davenport, Iowa.
Some northbound lanes will be closed as crews from Interstate Maintenance clean the northbound half of the bridge before June 1.
Then, beginning June 1, traffic will be switched to use the northbound lanes, with one open lane for each direction of travel, as structural repairs are made to the beam connections beneath the southbound lanes of the bridge.
"Motorists should expect delays due to the lane closures and plan trips accordingly," said a statement from the Illinois Department of Transportation.
The structural repairs will continue for several months, the statement said, with at least one lane open for each direction of travel at all times.
