IDOT US Route 30 at Dugan Road Underground Utilities Improvements

Sugar Grove, Illinois

V3 performed this storm sewer and box culvert installation as a subcontractor to Geneva Construction.
The project included roadway widening and drainage improvements along approximately 10,000 linear feet of US Route 30 from Dugan Road to Municipal Drive.
Triple box culverts were installed at two locations along US Route 30 to accommodate the widening. The first was 12 feet by 6 feet and included a total of 24 sections of box culvert. The second was 8 feet by three feet and included a total of 24 sections of box culvert. Both installations were constructed in two stages utilizing sheet pile to support the pavement and maintain traffic flow during construction.
An existing 12-inch watermain, located under the creek, was lowered to avoid a conflict with the box culvert elevation.
Prior to storm sewer installation, a detailed in-stream work plan was generated and permitted in order to maintain adequate drainage of storm events during construction.
Elements of stormwater management included bypass pumping from ditches and pipe around the work zone, as well as installation of temporary drainage pipe.
Additional work included the installation of new reinforced concrete pipe storm sewer along US Route 30 that tied into the box culverts.
