The lowest temperature a wet object can reach is what is called the "wet-bulb temperature." This can be several degrees lower than the "dry-bulb temperature," the amount can vary depending on the humidity (specifically atmospheric pressure). If that wet-bulb temperature gets below 0°C, then freezing is possible.
In order for said wet object to get close to the wet-bulb temperature, someconvectionneeds to occur in order to take that evaporated water away (i.e. wind).
This is one of the ways wind under a bridge can cause freezing under the right conditions.
