This is the basic syntax you need to get a junction listing for a highway article's exit list or interchange list, just place this in the appropriate place in the exit list table and fill in the variables. Note that this is a complete list of every variable that can be used with {{jct}} and that many are unnecessary in most cases. Variables that are empty can be omitted. This template currently only supports up to 4 routes per junction list.
{{jctname|country=|state=|1|2|3|4|5|6|7|8 |to1=|to2=|to3=|to4= |name1=|name2=|name3=|name4= |road= |city1=|city2=|city3=|city4=}}
For the above parameters here's what you should fill in:
{{jct}}
