Answers
True
False
The Correct Answer and Explanation is :
Answer: False
Highways and roads generally do not freeze before ramps and bridges. In fact, bridges and overpasses tend to freeze first. This is because of how they are constructed and the exposure they have to cold air.
Bridges and ramps are elevated structures, which means that they are surrounded by cold air on all sides. Unlike roads and highways, which are connected to the ground and receive heat from the earth beneath them, bridges and ramps do not have the benefit of that ground heat. The absence of soil or other materials below the surface allows them to lose heat more rapidly, which makes them more susceptible to freezing in colder temperatures.
Additionally, roads and highways have an insulating effect due to the ground beneath them, which helps to maintain a relatively higher temperature. This can delay the freezing process, even when temperatures are below freezing. Roads with a significant amount of traffic can also help to melt ice or prevent it from forming, as the friction from tires generates heat.
Another factor is the materials used in constructing roads versus bridges. Concrete and steel, common materials for bridges, are more prone to temperature fluctuations and can cool down quickly in cold weather, while asphalt, commonly used for roads, retains heat better due to its composition.
For these reasons, it is important for drivers to be especially cautious when approaching bridges and ramps in cold weather. These areas can be more dangerous due to their higher likelihood of ice formation, which can result in slippery conditions and increased risk of accidents.
