Bridges ice up faster b/c of the air that gets underneath it and ground does not have that air to make it freeze up that fast.

All of the above. Bridges are also made up of different material than the roadway. If you walk out onto a bridge on a cold day, you can feel the temperature change.

Bridges are off of the ground ,so cold air passes over and under at the same time.Most bridges are made up of concrete and or steel which in turn gets much colder than soil much faster.

actually a bridge has no solid ground so the air is not only on the top but its on the bottom. usually bridges are over water so that makes a difference on the temperature. that's the only reason that i know

The roads have run-off and ditches for precipitation to run into. A bridge has "walls" on the sides, keeping the moisture on the bridge.

the element that maximum human beings over look is the information. A bowling ball and a feather in a vacuum will hit the floor mutually. We obviously don't have a vacuum on earth with the aid of our atmoshpere, so so you might aspect in such issues as air resistance and floor section. also, that's factually ideal to assert the gadgets will fall on the same price of speed when you consider that gravity will result both both.
