Button Rock Dam Road Culvert Replacement

The existing 80” culvert failed and was replaced with a 20’ x 10’ concrete box culvert. A boulder drop structure was placed both upstream and downstream of the new CBC to facilitate the 8’ of grade drop. This project is a State of Colorado 2012 APWA award recipient for Design/Construction/Maintenance.
