It all depends on the design.
Some bridges did not even use sleepered track! The rails being fixed to longitudinal beams or timber baulks with tie rods.
If you want drawings then PM or better still e mail me and I'll send you some sketches.

Some rail bridges on less intensively used lines (into goods yards, etc) used ash ballast. The girder bridge crossing the River Windrush into Witney goods depot on the Fairford branch certainly used ash ballast. This curious example (well known to me) now devoid of track had a separate attached girder crossing (to the left with the white wooden safety hand rails) to allow the cart horses that were once used in the goods yard (for shunting wagons) to cross the river to the headshunt at Witney Junction:
Whereas others, as Frank above points out (girder types) used longitudinal wooden timbers running the length of the bridge, supported by large metal girders underneath with the rail fixed by chairs onto the timbers. However, this example at Witney Junction shows another variant where the horizontal rail sleepers were supported in an open fashion by metal girders beneath:
All three examples above, as I'm sure most of you are aware, are fairly typical GWR types. I'm not sure, however, if the original Witney Railway Company built these or whether they are later GWR replacements.
