Transportation

Since the firm’s founding in 1996, INTERRA (then Great Lakes Soil & Environmental Consultants, Inc.) has provided services to the Illinois Department of Transportation (IDOT), Illinois State Toll Highway Authority (ISTHA), and various counties and municipalities. INTERRA is selected to provide expertise and services on demanding interstate highway projects because INTERRA delivers.  Our wide array of services, consistent field personnel, and ability to provide sample data in near real-time upon test completion is a value-added benefit state agencies and construction teams rely on to make decisions to move the project forward.

INTERRA has provided various services for several years with the EOWA Project.

As can be seen in the following project profiles, INTERRA’s services have included monitoring and documentation of construction activities, materials coordination, geotechnical inspection and testing, and concrete and hot-mix asphalt plant and field inspections.
