During a reconstruction of US 136/Ill 1 in Danville , IDOT worked with both the city and individual homeowners in the area to choose treatments for the retaining walls adjoining their property.

These walls were necessary for engineering purposes, but rather than use standard concrete walls, IDOT helped choose various treatments that fit the style of each nearby home.

This stone arch bridge shown in the last three pictures is on the list of Historic Bridges in Illinois . Originally slated for complete replacement, concerns for preservation of this historic structure led to an innovative concrete liner design that allowed the basic structure to remain intact. Structure integrity was improved to withstand the loadings of modern trucks while preserving the original stone work.
