ABSTRACT: In this paper there will be an examination of the relationship between culvert design life and sustainability. 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 will be analyzed through the lens of sustainability. Sustainability will be addressed from the standpoint of climate change and the effect of storm events and through the four system conditions, created by Natural Step, as part of the framework for sustainable development. An analysis of culverts functioning as wildlife crossings will also be discussedHarvard Buenvironmental impacts in Canadian Rocky Mountain National Parks and animal crossings across highways. 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.
