Construction work for adding paved turn lanes and signals at the intersection of Iowa Highway 21 and Shaulis Road in Waterloo will require closing and detouring traffic beginning Friday (Sept. 16, 2016).

According to the Iowa Department of Transportation (IDOT), a marked detour will be used to direct Shaulis Road traffic around the work zone through late October. The detour route will use Kimball Ave. Orange Road and Hammond Ave.

IDOT officials said access to Shaulis Road from Iowa 21 west of the highway will be closed starting Friday, weather permitting. Access to Shaulis from Iowa 21 east of the highway will be closed at the end of September, weather permitting.
