DES MOINES, Iowa – June 7, 2023 – If you drive on the Iowa 415 mile-long bridge over Saylorville Lake near Polk City you need to know about an upcoming daytime maintenance project that may slow down your trip.

Drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones.
