The ability to create a straight bridge when the alignment transitions from tangent to a horizontal curve on the bridge. Currently the deck ends are controlled by the bridge skew from a radial line at the end of the deck rather than from the tangent section. This leads to the deck being skewed differently from the rest of the bridge rather than being parallel to the substructure units.

See the attached image for another example. This is the condition, I believe, that the OP was asking about. Please note, the examples are exaggerated to show conditions easier
I imagine this could be accomplished through creating a separate bridge alignment, but the ability to keep the structure tied to the roadway alignment would be ideal. here's another example of where a straight bridge on a curved alignment would be used. Sometimes, due to cost, clearance requirements, or the use of standardized precast units, a straight structure design is warranted even if the roadway is curved. It will be built wide enough to accommodate the roadway curvature across the deck. Although this isn't extremely common where I work, it does come up from time to time.

Perhaps a toggle that specifies "Deck to Follow Alignment" could be added that is checked by default. If unchecked, it allows the user to draw in or specify a structure centerline or auxiliary alignment as part of the bridge wizard or place deck process.
