Ardmore Roderick was a subconsultant and provided construction inspection engineering services to the Illinois Tollway for their portion of improvements to provide an interchange at Interstate Route 57 with Interstate Route 294. Improvements included new bridges along Tri-State Tollway (I-294) over Illinois Route 83 (147th Street) as well as roadway reconstruction and widening along the routes. Our team provided inspections for bridge demolition and reconstruction, pavement removal and reconstruction, drainage and electrical improvements. We were part of the same Phase III for IDOT improvements to the same location.
