{{Lua|Module:Jct}}
This template produces a junction listing for the junction list of a highway article, and can be used as an argument to {{para|road}} in a template for an intersection such as {{tl|jctint}}.

==Usage==
The full syntax is as follows.
<pre width="100%">
{{jct|country=|state=
  |to1=|1|2|county1=|dab1=|dir1=|name1=
  |to2=|3|4|county2=|dab2=|dir2=|name2=
  |to3=|5|6|county3=|dab3=|dir3=|name3=
  |to4=|7|8|county4=|dab4=|dir4=|name4=
  ...
  |city1=|location1=
  |city2=|location2=
  |city3=|location3=
  |city4=|location4=
  ...
  |extra=
}}
</pre>
Many parameters shown above are unnecessary in most cases, and can be omitted.

==Parameters==
Parameters {{para|'''in bold'''}} are most important.

===Location===
*{{para|'''country'''}} accepts the [[ISO 3166-1]] alpha-3 code of the country that the junction is in.  Use [[List of ISO 3166-1 codes|this list]] to find the correct code for the country.  [[Template:Jct/doc/country|These countries]] have had the necessary subtemplates set up; see that page for instructions on how to set up new countries.
*{{para|'''state'''}} or {{para|province}} may be used in place of {{para|country}} if the junction is located within one state, province, or territory in the United States, Canada, Mexico, or Australia.  The possible values are as follows:
**U.S. state: {{para|state}} accepts the two-letter [[United States postal abbreviations|postal abbreviation]] of the state.
**Canadian province: {{para|province}} accepts the two-letter [[Canadian subnational postal abbreviations|postal abbreviation]] of the province.
**Mexican state: {{para|state}} accepts the three-letter [[Administrative divisions of Mexico#ISO 3166 codes|postal abbreviation]] of the state.
**Chinese province: {{para|province}} accepts one of the two letter codes from [[Module:Road data/masks/CHN]].

===Intersecting routes===
*{{para|'''1'''}}, {{para|'''3'''}}, {{para|'''5'''}}, ..., {{para|&lt;2i-1&gt;}}, ... accept the type of the i<sup>th</sup> route at the junction.  Arguments may replace the numeric parameters, e.g., <code><nowiki>|I</nowiki></code> may be used instead of {{para|1|I}}.  The route types are defined as follows:
::For routes in the United States, see [[Template:Jct/doc/type/USA|this page]].
::For routes in Canada, the following designations are supported:
::*AB (Alberta) - '''Hwy''' (primary and secondary provincial highways)
::*ON (Ontario) - '''Highway''' (provincial highway, all types), '''RR''' (Regional Road, must supply a ''county'' argument for region)
::*QC (Quebec) - '''Route''' (standard route), '''A''' ([[Autoroutes of Quebec|Autoroute]])
::*MB (Manitoba) - '''Hwy''' (primary provincial highway), '''PR''' (secondary provincial highway), '''Winnipeg''' (Winnipeg city route)
::*NB (New Brunswick) - '''Route''' (''NOTE: Not all routes have shield graphics at present.'')
::*NS (Nova Scotia) - '''Trunk''' (trunk route), '''Hwy''' (highway), '''Route''' (other route)
::*PE (Prince Edward Island) - '''PE''' (all numbered routes except TCH)
::*All provinces - '''TCH''' ([[Trans-Canada Highway]])
::For routes in Australia, see [[Template:Jct/doc/type/AUS|this page]].
::For United Kingdom routes:
::* '''M''' = Motorway
::* '''A''' = A roads
:::''For A roads that have a motorway segment, example: A1(M), use '''M''' as the route type and the '''A1''' as the number''
*{{para|'''2'''}}, {{para|'''4'''}}, {{para|'''6'''}}, ..., {{para|&lt;2i&gt;}}, ... accept the route number for the i<sup>th</sup> route at the junction.  Arguments may replace the numeric parameters.
*{{para|dir1}}, {{para|dir2}}, {{para|dir3}}, ..., {{para|dir&lt;i&gt;}}, ... accept a string for the direction of the i<sup>th</sup> route at the junction, when not all directions are accessible, e.g., Interstate 10 east.
*{{para|name1}}, {{para|name2}}, {{para|name3}}, ..., {{para|name&lt;i&gt;}}, ... accept [[wikicode]] for the common name of the i<sup>th</sup> route at the junction.
*{{para|to&lt;i&gt;}} accepts any value.  The presence of {{para|to&lt;i&gt;}} indicates that the i<sup>th</sup> route at the junction is accessible indirectly via an earlier route in the list.
*{{para|county&lt;i&gt;}} accepts the name of a county the i<sup>th</sup> route at the junction is in, for disambiguating county routes.
*{{para|dab&lt;i&gt;}} accepts a string indicating the location for the i<sup>th</sup> route at the junction, for further disambiguating routes that may appear in multiple locations, such as Interstate business routes.  For example, {{para|dab1|Pennsylvania–New York}} gives <nowiki>[[Interstate 86 (Pennsylvania–New York)|I-86]]</nowiki>.

===Destinations===
*{{para|city1}}, {{para|city2}}, {{para|city3}}, ..., {{para|city&lt;i&gt;}}, ... accept the name of an in-state city listed on the guide sign at the junction, i.e., control cities.  The city is assumed to be in the same state as the junction, and will be automatically [[wikilink]]ed.
::{{para|areadab&lt;i&gt;}} accepts the area to be used for further disambiguating the i<sup>th</sup> city, such as a name that could refer to a [[town (New York)|town]] or a [[village (New York)|village]] within the same [[county (New York)|county]].
::{{para|countydab&lt;i&gt;}} accepts the name of the county to be used for disambiguating the i<sup>th</sup> city, e.g., for a town whose name coincides with another in a different county within the same state.
::{{para|location&lt;i&gt;}} accepts wikicode that overrides {{para|city&lt;i&gt;}}, and should be used if the destination city is located outside of the state the junction is in, or if the destination city has a Wikipedia page title that does not include its state (such as New York City, Los Angeles, or Chicago).
*{{para|extra}} accepts one of the following values to display a ''MUTCD'' intermodal icon along with route shields:
**'''airport''' for an airport
**'''bus''' for a bus terminal
**'''ferry''' for a ferry terminal
**'''rail''' for a passenger rail station
**'''light-rail''' for a light-rail station
:Specifications for additional types and custom shields may be added to [[Module:Road data/extra]].

===Appearance===
*{{para|noshield&lt;i&gt;}} accepts any value.  The presence of {{para|noshield&lt;i&gt;}} indicates that the shield for the i<sup>th</sup> route at the junction should not be displayed.
::{{para|noshield}} accepts any value.  The presence of {{para|noshield}} indicates that no shield should be displayed.
*{{para|nolink&lt;i&gt;}} accepts any value.  The presence of {{para|nolink&lt;i&gt;}} indicates that the i<sup>th</sup> route at the junction should not be wikilinked.  This is useful for a minor route that will never have an article.
::{{para|nolink}} accepts any value.  The presence of {{para|nolink}} indicates that all routes at the junction should not be wikilinked.
