Interstate 29 construction work restricts traffic in several locations in western Iowa

Posted on: March 29, 2010

SIOUX CITY, Iowa – March 29, 2010 – Work on Interstate 29 in western Iowa will cause several traffic changes in the coming weeks, according to the Iowa Department of Transportation’s (DOT) Sioux City construction office.

  • Northbound I-29 will be reduced to one lane to complete construction work begun last year in Harrison and Monona counties. Weather permitting, northbound I-29 will be restricted to one lane from after exit 89 (Iowa 127) to before exit 120 (Monona County Road E-24) to allow work to be finished. The final year of this Portland cement concrete paving project will begin once the remaining work from last year is completed. 
  • Both north- and southbound I-29 traffic may experience intermittent lane closures through April for patching work from Onawa to Sloan. The patching is the first stage of the final year of this hot mix asphalt resurfacing project.  The work will take place from after exit 120 (Iowa 175) to before exit 127 (Iowa 141/Woodbury County Road K-42).
  • Northbound Interstate 29 will be reduced to one lane for pavement repair through next week south of Sioux City. The project area begins after exit 127 (Iowa 141/Woodbury County Road K-42) to before exit 141(First Street and Sioux Gateway Airport). The pavement repair is expected to be in place until April 9.

The Iowa DOT reminds motorists to drive with caution, obey 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.
