Here's another one.
The first build I tried was ballasted deck bridges.
They are simple yet effective.
Materials used-
1/4" square poplar dowels for supports and the ladder style construction of the base.
1/4 × 1/16 basswood walk board planks.
1/4 luan to hold ballast.
Coat hanger for the handrails.
Danish Oil Medium Walnut Finish.
