Mississippi Boulevard in Bettendorf will be closed to all traffic Saturday between Kimberly Road and 14th Street.
Traffic will be detoured to U.S. Highway 67 (Grant Street) and Calvert Drive.
The closure will facilitate steel construction between two recently completed bridge abutments for the future westbound Interstate 74.
The work is weather-dependent, with a contingency date of Monday.
