IF and only IF I'm right. A bridge surface will freee before a rooad surface most likely because of the metal used to make the bridge which will freeze the bridge structure and start forming on the road.

Hope that answered your question :)

What is a bridge substructure?
The foundational or floating structure supporting the road surface portion of a bridge.
Why do the road on the bridge freeze quicker?
There are three main reasons why bridges freeze before roads. The first is that a bridge is exposed from below and above, unlike a roadway. Roads don't freeze over as quickly because they can take advantage of insulation and warmth from the soil below. Bridges, on the other hand, are beset with cold temperatures from all sides, which can cause them to ice over quickly. Bridges also freeze rapidly because many of them are located over cold spots, like frozen rivers or deep ravines. The third reason that bridges freeze before roads is their construction. The materials used in the core of a bridge are excellent heat conductors. As a result, they draw heat out from the inside of the bridge, transferring it to the surface where it is quickly lost when ambient temperatures are very cold. Bridges often quickly reach the general air temperature, so when the thermometer reads 32 degrees Fahrenheit (0 degrees Celsius), the bridge will freeze .
