Adapting Transportation Infrastructure to Climate Change
Last updated on April 6, 2023To provide transportation infrastructure that is resilient and adapted to the effects of climate change including extreme weather events, we must look beyond historical information to future trends and what they might mean for British Columbia.
With contributions from key partners such as the Pacific Climate Impacts Consortium (PCIC) and using the Public Infrastructure Engineering Vulnerability Committee (PIEVC) Protocol, the Province has undertaken initiatives to evaluate and address potential effects of climate change on transportation infrastructure, such as roads and bridges. Additional guidance and examples for including climate change considerations in transportation infrastructure engineering design work have been developed in collaboration with Engineers and Geoscientists British Columbia (EGBC).
These activities contribute to B.C. transportation infrastructure that is resilient, reliable, effective and efficient – and adapted to future climate conditions.
Transportation Infrastructure Engineering Design
The Ministry of Transportation and Infrastructure requires that potential impacts of climate change be considered in transportation infrastructure engineering design so that B.C.'s transportation infrastructure is adapted to climate changes. A climate language primer was also developed to clarify concepts and principles typically used in climate sciences.

Highway Transportation – Adaptation, Risk Studies, Climate Modelling
Climate change adaptation studies enable the Province to develop guidance to address potential future climate impacts on B.C.'s highway infrastructure and other infrastructure. This work includes climate modelling, risk analysis of climate change and extreme weather, examining infrastructure interdependencies and economic considerations and developing best practices. This promotes a resilient transportation system adapted to extreme weather and other climate change effects.
