Construction work on Iowa 1 near Martelle may slow down your trip beginning on Monday, June 12

CEDAR RAPIDS, Iowa – June 6, 2023 – If you’re driving on the northbound or southbound lanes of Iowa 1 in the Martelle area, the Iowa Department of Transportation is starting a project that may impact your trip.

Beginning on Monday, June 12 until late September, weather permitting, we’ll be working replacing the culverts under Iowa 1 between U.S. 30 and U.S. 151 near Martelle. While the roadway is closed, motorists will follow a marked detour route using U.S. 30 and Iowa 13/U.S. 151.

Help keep everyone on the road safer. 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. As in all work zones, you should stay alert, allow ample space between vehicles, and wear seat belts. 

The latest traveler information is available anytime through our 511 system. Visit; call 511 (within Iowa) or 800-288-1047 (nationwide); stay connected with 511 on Facebook or Twitter (find links at; or download the free app to your mobile device.
