A thawing tube guide is prepositioned at the opening of a culvert to facilitate maintenance personnel in passing a culvert thawing tube with a power head into a culvert opening which is covered by ice, snow or an ice slurry. The culvert thawing tube guide includes a guide pipe having a discharge end positioned within the culvert and an inlet end positioned in at an easily accessible location. A cap and a reflective material are attached to the inlet end to prevent the accumulation of debris within the tube and to aid in detecting its location respectively.
