The first beams and bracings of a truss bridge, still supported by pilings, on a frozen river. Two people are visible at right, and a third, farther down, stands near a pile driver.
Cables or ropes run from standing girders (which form part of the truss) to horizontal girders. A person is standing on the bridge surface or on a girder.

A truss bridge under construction. The surface is not yet built, and planks of wood extend from girder to girder to make a walkway. What appears to be a pile driver stands at the end.
A truss bridge under construction. A ladder-like structure with rungs goes diagonally to a top girder. A construction worker sits against the bridge at far left.
