Addressing Climate Change Impacts on Infrastructure: Preparing for Change - Transportation
This factsheet explains the effects of climate change on transportation infrastructure and what adaptation measures can be taken to address them.
Changes in the variability and magnitude of temperature, precipitation, rising sea levels, and extreme weather events can affect transportation infrastructure. Severe rain can cause temporary or permanent flooding of roads, bridges, and ports. Damage to structures or increased wear and tear can lead to higher maintenance costs due to damage. And services can be disrupted by weather events.
Transportation-related adaptation options include designing back-up services, constructing storm surge barriers, and elevating roadways. In some instances, infrastructure may need to be relocated.
The factsheet describes the ways that climate change impacts can affect a range of transportation decisions. For example, how higher rainfall affects decisions on project development and the impacts - such as design specifications - that should be considered.
It also provides a full spectrum of possible climate impacts and adaptation measures that can be taken to address each one.
