Hello and welcome to the Interstate Highways Task Force! If you would like to help, please jump in and start adding or editing.

Scope and goalsEdit

This task force covers all Interstate Highways in the United States. The goal is to standardize the format of the Interstate Highway articles, and to generate some featured articles as well.

Naming conventionsEdit

  • Interstate x - main and auxiliary interstates that are not nationally duplicated.
  • Interstate x (state) - auxiliary interstates that have duplications and are single state. "Interstate x" becomes a disambiguation page.
  • Interstate x (state-state) - secondary interstates that have duplications and enter multiple states. Western/southernmost state is listed first. If the Interstate enters more than two states, then list all states in the name, beginning with the western/southernmost state. "Interstate x" becomes a disambiguation page. Interstates 76, 88, 86, and 84 also use this convention, since there are two of them. However, only the states at the termini should be included in the article title. "Interstate x" becomes a disambiguation page.
  • For articles about a state-specific segment of a longer Interstates, state-detail Interstate pages are to be named "Interstate X in Y", where X is the Interstate number and Y is the state name.
  • Exceptions: Interstates in Alaska and Puerto Rico are listed under Interstate Highways in Alaska and Interstate Highways in Puerto Rico.


All primary interstate highways go here with a 2 digit sort code (08 for I-8, 85 for I-85, etc.)
All interstates that run through that state go here. For 2dis, use a 2 digit sort code as above. For 3dis, follow this example: 05-7 for I-705. 25-8 for I-825. Warning: some of these categories still use the lowercase H.
All 3dis go here with the 05-2 sort key (for example).
For Business Loops and Spurs.
Used to identify that other articles in addition to Interstate X (state detail pages for X, bridges, U.S. and Interstate Routes that runs along X) can be categorized in the same collection as Interstate X. Example: San Francisco-Oakland Bay Bridge and Interstate 80 can belong to Category:Interstate 80.


The infobox for Interstates is {{Infobox road}}, with type=I. If it is intrastate, add a state= line.


Shields for Interstate Highways have been created in the format I-X.svg, where X is the Interstate number. See Commons:Interstate shields for a gallery.




Designates this article relating to the Interstate Highway System as a stub. Articles are listed in Category:U.S. Interstate Highway stubs.

Browse numbered routesEdit

For Interstates entering two or more states only.

Type the following code at the bottom of the article after {{Interstates}}.

{{start srbox}}
{{end box}}

In between the start and end templates, the state browse templates should be added. These templates exist in the form

{{XX browse|previous_type=|previous_route=|route=|next_type=|next_route=}}

where XX is the two-letter abbreviation of the state in lowercase (California is ca, New York is ny, etc.).

For the above parameters here's what you should fill in:

  • previous_type: previous route (by number) in that state. Interstate, US (for U.S. routes), and (2-letter state abbrev.).
  • previous_route: route number.
  • route: a link to the list page for that state's highway system.
  • next_type: the same as previous_type, but for the next route.
  • next_route: same as previous_route, but for the next route.

Project noticeEdit


WikiProject U.S. Roads (Rated NA-class)
This page is within the scope of the U.S. Roads WikiProject, an attempt to build a comprehensive and detailed guide to state highways and other major roads in the United States. If you would like to participate, you can edit the article attached to this page, or visit the project page, where you can join the project and/or contribute to the discussion.
  NA  This page is not an article and does not require a rating on the quality scale.

Goes on talk page of each article. For assessment, see Wikipedia:WikiProject U.S. Roads/Assessment. Only include states if there are no separate articles about the route in those states (like Interstate 95 in Virginia).



Goes on each primary highway (except 76, 84, 86, and 88) that has three-digit Interstate highways, and also goes on each three-digit highway. (For Interstate 10 use {{3di|10}}, etc.


Template:I-84 aux

Use an additional parameter for Interstates 76, 84, 86, and 88 (east and west for all). Example: Use {{3di|84|east}} for the I-84 in the east. If the box is empty (or incomplete or inaccurate), then create (edit) Template:3di 84 (east). The format for Template:3di xx (xxxx) is the same as the format for Template:3di xx.


Goes on every article on a primary highway.
