This style guide provides the foundation for creating, editing and maintaining road junction lists across Wikipedia articles. Most road articles should use a table to indicate junctions. There are cases, such as a major transcontinental highway with parent and section-detail articles, where only a partial junction list, in a list form, is appropriate.

Using this style guide

As road design, jurisdiction and construction techniques vary significantly around the world, so do junctions and signing standards. While this document has been developed to provide a basis for a uniform presentation of road junction information, not all information is applicable to all roads in all regions. Thus, certain provisions of this guideline are noted as being for optional use. In some cases, this Manual of Style page presents different methods of expressing the same thing. When creating or editing junction lists for a particular country or state, check with an appropriate road-related WikiProject for that region. The various projects may have adopted practices or preferences regarding some of the optional provisions presented below.

Summary lists

These should be formatted as a hierarchical list consisting of the shields and names of intersecting highways and locations.

Tables

Standard columns

Generally, the following columns should appear from left to right in the following order:

To comply with MOS:DTT, and promote accessibility on the part of our readers who use assistive technology like screen readers, tables or the templates used to create tables shall use: !scope="col"|<column name> (or the HTML equivalent) as the code to create column headers. Furthermore, each row of the table shall use !scope="row" style="text-align: right;"|<table data> (or the HTML equivalent) for the primary distance number. To keep the cells right-aligned, use class="wikitable plainrowheaders" (or the HTML equivalent) in the header coding.

Colors

The use of colored backgrounds in the table is optional. If a list includes backgrounds, a key below the table must be included. Color should not be the only method to impart the information. For the benefit of colorblind readers or persons using screen readers, the Notes column must include the information. The following table lists the standardized colors with standardized meanings. Additional colors may be used to supplement the standard colors below. These colors must be compliant with this guideline and WP:COLOR, and they must be included in the key below the table. The template keys listed below are built into ((Jctbtm)).

Color key
Color Use Template keys Notes
#ddffdd Concurrency terminus concur
#d3d3d3 Closed closed Previously complete and open, but now closed (temp. or perm.)
#ffff99 HOV only hov Interchange/intersection only accessible to high-occupancy vehicles (HOV)
#ffdddd Incomplete access incomplete Some ramps/movements missing
#dcdcfe ETC/Tolled etc, toll Interchange or bridge requires the use of electronic toll collection or is otherwise tolled as an exception to the rest of the roadway
#ffdead Proposed/unopened unbuilt, proposed Interchange/intersection proposed, under construction and/or not yet open to traffic
#dff9f9 Route transition trans Indicates a transition from one route number to either another route number, or a section without a route number, along a named road

Table footers

A standardized table footer template has been implemented with ((jctbtm)). The necessary color keys can be individually specified using the |keys= parameter as described in the template documentation. Both templates close the wikitable syntax and generate a conversion key. This conversion key is required on all tables unless both miles and kilometers are listed on the table. Samples of this key are used in the examples section below.

1.000 mi = 1.609 km; 1.000 km = 0.621 mi
1.000 mi = 1.609 km; 1.000 km = 0.621 mi
1.000 mi = 1.609 km; 1.000 km = 0.621 mi

What to include

The following items should be included or excluded in tables on grade-separated highways.
