Template:Infobox road/doc/conversions and consolidations

The following charts document the previous conversions and consolidations that were made to unify most usages of the various international highway infoboxes into Infobox road (IR). As of February 2012, only one template, infobox Australian road, has not been consolidated, although most of its functions have been supported by IR. Future discussion may or may not lead to any change of that situation.

Related templates
In addition, infobox road small (IRS) was developed which merged together three other templates: ibus, shban, and usban for business routes of Interstate, state and US Highways in the US. In addition, it now handles anything handled by its full-fledged sibling in condensed form.

For junctions and interchanges, infobox road junction (IRJ) handles situations previously handled by Malaysian expressway interchange, infobox Flyovers, and Info Japan Interchange.

IR, IRS and IRJ all use the same color-coding subtemplates to produce a consistent look for a country's roadway infoboxes. For US-specific system articles and lists, a fourth template, infobox state highway system also uses the same color subtemplate core. A future global analog may be developed.

Previous conversions and mergers
Infobox road has been updated to accommodate the following templates. Some templates have remained in another capacity, and those will be marked ✅.

US state templates previously consolidated
Previous to 2010, the US had multiple infobox templates. Some of these were merged together back in the 2006–07 timeframe to create infobox road initially. Most of these were state-specific, and some were created to address unique situations in those states, like multi-segmented highways. With the recoding to convert infobox road to use infobox, these last infoboxes were merged into the main one. At that point, any remaining state-specific infoboxes were shell templates that called the main one, and they were deleted.
