Where is ice most likely to form on the road?

Ice is most likely to form on bridges and in shady areas due to several factors. Bridges are more susceptible to freezing because they are exposed to air on both sides, which allows them to cool down faster than the ground. The materials used in bridges can also lose heat more quickly than the surrounding roadways, creating a condition where ice can form more readily.

Shady areas, on the other hand, do not receive direct sunlight, which means they do not warm up as quickly as areas exposed to sunlight. This prolonged exposure to cooler temperatures can cause moisture on the road's surface to freeze, leading to icy conditions.

In contrast, open areas and well-lit areas usually receive more sunlight and heat, which helps prevent ice formation. Busy highways might have more traffic that can help keep the roadway surface warmer due to the friction generated by vehicles, making ice formation less likely there as well.
