16. A screening system for a vibratory machine, the screening system comprising:
a first screen panel comprising a plurality of first bridge elements that defines a plurality of first apertures therethrough in a vertical direction, a first perimeter of the first screen panel being defined by at least a portion of the first plurality of bridge elements, wherein the first screen panel is modular and removable from the screening system;
a plurality of first partial bridge elements extending away from the first perimeter of the first screen panel;
a second screen panel comprising a plurality of second bridge elements that defines a plurality of second apertures therethrough in the vertical direction, a second perimeter of the second screen panel being defined by at least a portion of the second plurality of bridge elements, wherein the second screen panel is modular and removable from the screening system independently of the first screen panel; and
a plurality of second partial bridge elements extending away from the second perimeter of the second screen panel, wherein the plurality of first partial bridge elements and the plurality of second partial bridge elements meet along an intersection line and define a plurality of intersection apertures when installed in the screening system.
