Box Culvert Replacement

Existing box culvert which dated back to the early 1900’s had deteriorated to the point that the lower portion of the walls had eroded away, as well as a portion of the roadbed behind the walls.  This erosion created a sinkhole in First Street causing the City to close the street and the need to make an emergency replacement.  First Street is one of the main farm to market routes to the elevator.  Additionally, a major City sanitary sewer main rain through the middle of the box culvert.  DGR worked with the Army Corps of Engineers and the Iowa DNR to install a new 10’ x 8’ RCP box culvert, as well as sanitary sewer replacement and water main adjustments such that the street could be reopened to farm to market traffic as harvest began.
