When I was developing the Footbidge with Lifts https://www.cgtrader.com/3d-print-models/games-toys/other/model-railway-modern-foot-bridge-with-liftThe amount of items was getting quite large so I just went with one width of the central span and that was 160mm

This add-on is a range of difference span lengths 96mm, 128mm, 192mm and 224mm, I have also included the 160mm version if someone wants just this part of the bridge for another project.

The design has been tested on the Bambu Labs A1 series printers.

This item has been designed at OO gauge, 1/76.2 scale.For HO Gauge print at 87%, 1/87 Scale,For O Gauge UK print at 175%, 1/43.5 scale,For O Gauge International print at 158%, 1/48 scale,For TT Gauge print at 63.5%, 1/120 scale,For N Gauge UK print at 51.5%, 1/148 Scale, (Caution: I have not test printed this in N gauge scale).
