The key factor is that bridges and overpasses are elevated structures, meaning that they are exposed to cold air both above and below the surface. This makes them more susceptible to temperature changes compared to regular roads, which have the ground beneath them providing some insulation.<\/p>\n\n\n\n<p>When temperatures drop, the road surface on a regular street is somewhat insulated by the ground underneath it. The earth acts as a buffer, slowing the cooling of the road surface. However, overpasses and bridges, being elevated, have no insulation from the ground beneath. Cold air circulates around the entire structure, cooling the surface more quickly. As a result, the temperature of the bridge surface can drop more rapidly, causing it to freeze before the surface of regular roadways.<\/p>\n\n\n\n<p>This phenomenon is particularly dangerous because drivers might not anticipate that bridges will be icy while the rest of the road is clear. The black ice that can form on overpasses and bridges is especially hazardous because it can be difficult to see, making driving conditions treacherous.<\/p>\n\n\n\n<p>In contrast, regular roadways, with their ground insulation, often freeze more slowly and may not experience the same sudden drop in temperature. In addition, the salt and sand used on roadways may help to prevent freezing, though this is less effective on elevated surfaces like bridges and overpasses.<\/p>\n\n\n\n<p>For these reasons, it&#8217;s important for drivers to be aware of the potential for icy conditions on bridges and overpasses, even if the rest of the roadways seem clear.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In winter weather, overpasses and bridges:AnswersAre affected in the same way as other roadways.Freeze after the rest of the roads.Freeze before the rest of the roads.Thaw out before the rest of the roads.
