Standard Design Lane Loaded (/ Load Element) Width Locations
Description
This sub-form is used to specify the lateral position of the Standard Design Lanes within the carriageway. It also allows the width to be varied from the standard 3.2m width of the Standards Australia AS 5100, Part 2 Bridge Design Code to the standard 3.0m width of the AUSTROADS '92 Bridge Design Code and NAASRA.
For a railway configuration the lateral position and gauge of the railway tracks can be defined here.
