    anti-gravity devices? lol

    Well like most bridges it is modular using steel to tie the pieces together laterally (and mortar) for tension most commonly used is a rebar infrastructure or steel cables. This lateral tension spreads out the stresses/weight load fairly evenly to be distributed downward via the vertical support pillars (again employing steel). Being concrete there will also be floating joints to allow for expansion due to heat cycling.

    the steel bars run along the length of the bridge ?

    Through the modular pieces. If you looked at the modular concrete section you would see it is not solid and the steel passes through these sections. You can think of a string of pearls as a simplistic example.

    Here's a link with some pics to help further demonstrate:

    Note the sections are hollow and the holes within the concrete walls for the steel to pass through.
