A detour will be established for 66th Avenue directing traffic north to Oralabor Road.

Delays on Iowa 415 are anticipated during the morning and evening rush hours. Motorists are encouraged to consider alternate routes. Motorists on Iowa 415 are asked to observe warning messages on electronic signs and be alert for any traffic backups that may occur.
