A section of interstate 680 in Pottawattamie County will have a lane closure due to continuing bridge work.

The right lane of eastbound 680 between I-29 (exit 71) and Pottawattamie County Road L-34 (exit 21) in the construction area near Crescent will be closed. The open lanes will have a smaller width restriction.

The bridge work is expected to last until mid-November.

The Iowa DOT reminds motorists to drive with caution, obey posted speed limits and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones.
