Bridges and overpasses in Boca Raton, Florida and other areas can freeze before the surrounding roads, creating dangerous driving conditions that can last for days. This is due to the unique way bridges and elevated roadways are constructed, which makes them more susceptible to freezing temperatures.

Why it matters

Knowing why bridges freeze first and what to look for can help drivers avoid dangerous situations and accidents when temperatures drop. This is especially important in areas like Boca Raton that don't experience frequent freezing weather, where drivers may not be as familiar with these hazards.

The details

Bridges and overpasses freeze before regular roads because they are exposed to the elements on both the top and bottom, allowing cold air to circulate more freely. Roads, on the other hand, are insulated by the ground beneath them, taking longer to freeze. Additionally, bridges lack the heat-retaining properties of the ground, causing them to cool more quickly. This can result in bridges remaining icy even after nearby roads have thawed.
