The bridge is sized for HotWheels-style cars. It is a full-width print on a Prusa i3 MK2/3[S][+]. When its done you'll end up with three components: the center span and the two approaches. See the gcode notes for the quantities needed for each printed part.
The yellow lane marker is achieved with a color change.
The only parts with support are the road deck for the approaches. It is slightly annoying to remove. You may get acceptable results without support, but I didn't try. If you do, please let me know in the comments!
The assembly instructions are the same for the center span and the sides. You just need super glue, a couple spring clamps, and a weight
Assembly isn't hard, but I also didn't optimize the design for super quick assembly. Please post any questions or suggestions!
