CAÑON CITY, Colo. (KRDO) — The Colorado Department of Transportation (CDOT) is halfway through a monthlong project to repair two aging culverts under US 50 at the 1st Street intersection.
The culverts connect two sides of an irrigation channel that has a reduced water flow before the growing season, and that makes working on the project easier.
Wayne Pittman, a CDOT engineer, said that crews are replacing the liners in the culverts; each of them is 72 inches in diameter.
He also said that a balloon is a key part of the repairs.
