Lane closures on the Iowa 92 bridge over Duckbill Creek near Carson begin on Tuesday, May 30

CRESTON, Iowa – May 12, 2023 – Motorists who travel on Iowa 92 between U.S. 59 and Pottawattamie County Road M-47 east of Carson should be aware of an upcoming bridge deck replacement project that could slow down their trip.

Beginning on Tuesday morning, May 30, until Thursday, Aug. 24, weather permitting, construction crews will work on replacing the bridge deck on the Iowa 92 bridge over Graybill Creek, 1.2 miles east of the junction with U.S. 59. Motorists on the bridge will be directed by traffic signals. A 10-foot-4-inch lane-width restriction and a 15-foot height restriction will be in place during this project.

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.
