Drivers, get ready for more delays as you cross the Mississippi this summer.
Work to wash the Centennial Bridge began Wednesday morning. The outside Iowa-bound lane will be closed this week while crews clean the upriver side of the bridge.
Then starting Monday June 1, traffic will be changed to one lane in each direction while construction crews complete work left over from last year.
The work is expected to take several months. Drivers are asked to slow down and watch out for workers in construction zones.
