How hot does the pavement and steel in bridges get in the sun?

In direct sunlight, pavement temperatures can rise to between 140°F to 160°F (60°C to 70°C), while steel surfaces, such as those in bridges, can reach even higher temperatures, often exceeding 180°F (82°C) or more. Factors like color, material, and environmental conditions can influence these temperatures. Such heat can pose risks for both structural integrity and safety for pedestrians and vehicles.
