In this paper the relationship between culvert design life and sustainability is analyzed. The design standards that apply to culvert design are AASHTO (American Association of State Highway and Transportation Officials), CHBDC (Canadian Highway Bridge Design Code), and AS/NZS (Australian and New Zealand Standards). These regulatory frameworks are analyzed through the lens of sustainability. Sustainability is addressed from the standpoint of climate change and the effect of storm events and through the four system conditions, created by “The Natural Step”, as part of the framework for sustainable development. An analysis of culverts functioning as wildlife crossings is also discussed. Factors influencing design life are often neglected, and as a result can have hidden costs of repeated installation and ecological damage. In this paper based on our research, we have discussed that it is probable that culverts that have a longer design life will have a better sustainable position pertaining to ecological impacts.
