Why bridges freeze in front of the roads?
Most people who live in cold regions have seen signs that call the "bridge freezes in front of the road", and many people are aware that caution should be used in the bridges during cold weather because they can easily freeze. Bridges freeze in front of roads for many reasons, most of which include very basic science. Be aware of the conditions that cause bridges to freeze in front of the roads, make you a better driver, and if you live in a cold area of the world, make sure that newcomers in your area are aware of the risk of bridges in cold or ice weather. The first is that, unlike the road, the bridge is exposed from below and up. The roads do not freeze so fast as they can use insulation and heat from the soil below. On the other hand, the bridges are with low temperatures from all sides, which can cause the ice to be fast. The bridges also freeze quickly, because many of them are lounged in cold places such as frozen rivers or deep ravines.
The third reason Bridges freezes in front of the roads is their construction. The materials used in the bridge core are excellent thermal conductors. As a result, they pull heat out of the bridge and transfer it to a surface where they are quickly lost when the ambient temperatures are very cold. Bridges often reach general air temperature quickly, so when the thermometer reads 32 degrees Fahrenheit (0 degrees Celsius), the bridge freezes.
When driving on the bridges in ice weather, you should be careful even if you don't see ice on the bridge. Sometimes the ice can hide under the stains of snow, causing you to lose control. This is especially true in areas that they regularly carried, sand or plow; On the bridge, the accumulation of ice and snow could settle, which is very dangerous. In addition, the LED can sometimes be difficult to see on dark roads, especially at night when the temperatures of the ambient temperatures still cool down.
because bridges freeze in front of the roadRegeal that bridges are frozen when the ambient temperature is very cold, even if the roads are clean. In cold weather, they always run carefully and use chains or snow tires in areas where they are recommended. It is also a good idea to regularly check the wear of the tread and if wearing it, you should change the tires, as it can be very dangerous on ice roads. If you lose control of your car on the ice patch, remove your leg from the accelerator and concentrate on the driving from the skid; Suddenly do not take or sharply turn the wheels, as this can cause to slip on, slip or overturning.
