How Can Climate Change Affect Highway Drainage Systems?

Flooding is responsible for a lot of highway damage. Climate change can lead to an increase in temperature which may cause water to freeze faster, causing problems when it melts. More powerful and heavier rains can also lead to flooding as water takes longer to drain away. In addition, as more people move into more densely populated areas and build new neighbourhoods, there’s often less land available for storm drains and other stormwater management systems. This could lead to more flooding than has historically been seen. Storms that used to only occur every 10 years are happening more frequently and with higher intensity due to climate change.


What is climate change?

Climate change is a phenomenon that occurs when the Earth’s average temperature increases (or decreases) over time, and it can be caused by natural factors such as volcanic eruptions or solar activity. The effects of climate change are often felt in the form of increased temperatures, increased precipitation and more frequent extreme weather events.


The highway drainage system

The highway drainage system is made up of systems that collect rainwater and snowfall. These systems include pipes, culverts, ditches and tunnels that are used to carry water away from roads and bridges. As climate change progresses, melting snow will cause more runoff into these drainage systems, which could lead to increased flooding if not properly managed.


Effects of climate change on highway drainage system

The highway drainage system is designed to handle the amount of water it receives from precipitation, partly by removing excess water from the highway surface. If there were an increase in rainfall due to climate change, then this system could be affected.



The most obvious effect of climate change is the rising sea levels. Climate change will cause coastal areas to be more prone to flooding, as well as affect those who live near rivers and streams. Since many coastal areas are likely to become swamped by rising sea levels, the health and safety of people living near rivers and streams may be affected. Water levels are expected to rise steadily over the next century, with some regions seeing significant rises in water levels by the end of this century.


Degradation of the system

Climate change will also affect transportation networks such as roads and railways, which are vital for transporting goods and people across a country’s borders. The surface of roads becomes uneven due to melting snow, meaning that vehicles have to be driven at lower speeds than normal, increasing traffic congestion and making it harder for vehicles carrying heavy loads to manoeuvre properly. Climate change may also affect the quality of asphalt used for road construction, which could result in cracks forming more frequently than before.


Changes in storm patterns

Increased storm patterns may also make it more difficult to maintain highways, especially in areas where there are many curves or hills that require maintenance crews to use heavy equipment like graders or bulldozers. In addition, extreme weather conditions may create more frequent and intense storms, which could lead to a lack of workers available during those times due to injury or death caused by falling trees or rocks blocking traffic lanes.

Changes in precipitation patterns may also lead to increased erosion along highway shoulders as well as other areas where runoff collects during storms. This can cause surface water drainage pipes located near these areas to become clogged with debris, which can lead to leaks and serious damage if not repaired quickly enough before they freeze over.


Increase in temperatures

Climate change will make it harder for drainage systems to function properly because water levels will rise faster than they have been able to do in the past. As temperatures rise up towards 30 degrees Celsius (86 Fahrenheit), concrete pipes may not be able to handle this level of heat without cracking or crumbling under pressure from the rising water levels inside them. This means that there could be more problems with drainage systems than there are now at this stage in time because they won’t be able to handle higher temperatures as well as they have been able to do so far in our planet’s history.


More powerful and heavier rains

Climate change is causing more frequent and intense storms, which can cause flooding. These storms are also bringing more rainfall to areas where roads and bridges are located. The increased amount of precipitation can overload the drainage system, causing it to fail.


Life span reduction of concrete drainage pipes

Heavy rain creates runoff that flows into concrete drainage pipes. As this water flows through the pipes, it cracks them, which makes them weaker over time and leads to leaks or breaks in the pipe network. When this happens, road crews must replace these pipes at great expense.


Damage to infrastructure from flooding

A flood can damage or destroy many types of infrastructure along a highway. For example, when a bridge is flooded, traffic may be diverted off the bridge while repairs are being made. Bridges are also prone to corrosion due to saltwater intrusion during flooding events, which can weaken their structure over time and make them more vulnerable if they’re hit by another flood event soon after the first one occurred.


More frequent and intense storms

There are a number of ways climate change can affect highway drainage systems. The most common is due to increasing the frequency and intensity of storms. As global temperatures rise, more intense storms will occur worldwide. These storms will carry more rain and snow, which will increase runoff into local rivers and streams. This runoff can cause flooding and damage infrastructure that was not designed to handle the increased flows.


Higher energy demand for snow removal

Another way climate change can affect highway drainage systems is by increasing energy demand for snow removal. As global temperatures rise, winter storms will bring more snowfall to local roads and highways in many parts of the world. This means that snow removal trucks will be needed more often than before, which increases fuel costs for these fleets.


Extremely cold weather conditions making it harder to work on repairs

Extremely cold weather conditions making it harder to work on repairs is another way climate change can affect highway drainage systems. Extreme cold makes it harder for workers to work outside during winter months because they don’t have access to heated buildings or vehicles capable of driving through extremely cold weather conditions without stopping for extended periods of time (e.g., due to ice on roadways).


Benefits of Highway Drainage System Preservation

Highway drainage systems are designed to drain excess water from the highway, but they can also be used to prevent erosion and sedimentation.


  • Prevention of erosion and sedimentation: Erosion and sedimentation can cause problems for drivers, especially if they occur at a critical point in the road. A highway drainage system is a great way to prevent these issues from occurring.
  • Improved Water Quality: A highway drainage system will keep water from accumulating on the surface of the road and will allow it to flow away into a ditch or culvert, where it can then flow into an already existing drainage area and be properly treated by an appropriate filtration system. This means that you won’t have to worry about an increased risk of flooding.
  • Reduced Flood Risk: A good highway drainage system will help prevent any sort of flooding by keeping water out of the roadway, which helps reduce the risk of accidents due to slippery roads or other safety concerns related to wet conditions.
  • Increased Wildlife Habitat: The best thing about having a highway drainage system installed by your local construction company is that they can supply everything you need at one time. This makes it much easier for you than trying to find all these different items separately – it saves time and money.


Final Thought

Climate change could potentially cause a rise in global temperatures and sea levels. This would have several effects on the rate of water evaporation and precipitation, which can then cause flooding. Rainfall is also something to look out for as it would likely become heavier. If rainfall becomes heavier, storm events would likely become more intense. With the influence of warmer temperatures and higher sea levels, flash floods and increased stream-flow periods would happen more frequently resulting in lower-quality highways drainage systems that are vulnerable to leaks.
