Trail Detour Map

In early April, crews on this project began repairing the South Douglas Creek box culvert in Colorado Springs, where it flows under I-25 (near Ellston Street)—a site damaged during the 2013 floods. Specifically, the team will:

  • restore and seed roadway embankments;
  • extend the inlet and outlet;
  • remove sediment and debris; and
  • place erosion-control materials and boulders to prevent scour.
