The Iowa Department of Transportation’s Sioux City Construction Office reports ramp shoulder construction work, in conjunction with the Interstate 29 interchange reconstruction project, will require closing northbound I-29 on- and off-ramps at Salix (exit 134) beginning at 8 a.m. Tuesday, May 30, until Tuesday, June 13, weather permitting.

Motorists will be directed around the northbound I-29 ramp work zone onto a signed detour route using Woodbury County roads D-51 and K-45. Upon completion of the northbound I-29 ramp construction work, southbound I-29 on- and off-ramps will be closed for approximately two weeks for shoulder construction work. Traffic will be detoured around the work zone using Woodbury County roads D-51 and K-25.

The Iowa DOT reminds motorists to 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, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
