INTERRA provided construction inspection, management and materials (QC/QA) services for the reconstruction of the $725 million Dan Ryan Expressway reconstruction project for the full duration from 2004 to 2007. The Illinois Department of Transportation (IDOT) reconstructed the Dan Ryan Expressway between 31st and the I-57 Interchange. The vastly improved expressway included an additional lane in each direction, a reconfigured skyway interchange, and significant enhancements to the local access roads that run parallel to the expressway.
As a member of the project team, INTERRA contributed its expertise, and inspection and testing services to help ensure that this highly complex, long-term project was completed on schedule, with minimum disruption to one of the highest volume routes into and out of the City of Chicago.
