Which type of roads is particularly susceptible to icy conditions in colder weather?

Bridges are particularly susceptible to icy conditions in colder weather due to their unique construction and exposure. Unlike regular roadways that have the ground beneath them, bridges are elevated and allow cold air to circulate above and below. This means that the surface of a bridge can freeze more quickly than other types of roads, as it is not insulated by the earth, which retains heat. Consequently, drivers should be especially cautious when crossing bridges during winter conditions, as they may be icy even when the roads leading to them are not.

Additionally, while other types of roads like residential streets, highways, and back roads may also experience icy conditions, they typically do not cool down as rapidly as bridges, making those elevated structures riskier in winter weather scenarios.
