Mattis Avenue Over I-74 & I-57 Bridge Replacement

New bridges for an updated interchange support a regional increase in freight and traffic volume.

Replacing and lengthening two bridges over I-74 and I-57 prepares the bridges for future ramps anticipated as part of a reconstruction of the I-57/I-74 interchange. Other improvements include earthwork, drainage modifications, and lighting. As a critical member of the construction inspection team, Ardmore Roderick assisted with survey and material testing and ensured the contractor performed in accordance with contract documents.
