Template:Infobox NC Route/doc

This is the basic syntax you need to get a complete routebox on the article page, just place this before any other text and fill in the variables. Variables that are empty can be omitted. 

Explanations for each parameter are found below. Italicized parameters are optional. References are allowed and encouraged.
 * type: US for U.S. Routes, NC for state routes.
 * article_route: This is the number of the route the article is about.
 * alternate_name: Use in situations where the entire route has another name.
 * maint: Agency that maintains the route.
 * map: A map of the route.
 * length_mi: This is the length of the route in miles. If you specify beyond integers (i.e. add a decimal value), you will need to set length_round as described below.
 * length_round: If your value for length_mi is a whole number, you can omit this. Otherwise it needs to be set to the decimal precision of the length_mi parameter.
 * length_ref: To do what a good article writer should, provide your reference for the length of the route using the standard &lt;ref&gt; method.
 * length_notes: Notes regarding the length.
 * established: Year route was established. If a route has been pulled back or extended, consider the original establishment date of that route. If it has been moved entirely, use the date it was last moved. Provide a reference and wikify the date (if in MM/DD/YYYY format).
 * decommissioned: Year route was decommissioned, if applicable.
 * direction_a: This should be either south or west to keep in accordance with the U.S. Roads parent project, which lists termini and junctions in progression travelling from West to East and South to North. Use the signed, not general, direction of the route.
 * starting_terminus: This is where the route begins and is either at the southern terminus or western terminus. Recommended use: < > <> in <>
 * For example: [[Image:US 52.svg|20px]] US 52 in Winston-Salem
 * If the route ends at a state line, use either the municipality on the North Carolina side or, if the route ends across from a major city in the other state, use that city instead, suffixing it with the appropriate state abbreviation (such as SC for South Carolina).
 * Per WP:USRD/INNA, shields are to be 20px in height.
 * Sadly, not every terminus is simple. Use comma-breakline syntax (literally , ) and group shields first, then route numbers... and then group further across Interstate, U.S., and NC State Route lines. See Illinois Route 15 and North Carolina Highway 211 for examples.
 * junction: all junctions this route has with U.S. highways, expressways or Interstates. All other junctions, such as county routes, state routes that are not limited access expressways, or locations where a route passes over/under a U.S. highway/expressway/Interstate but does not intersect it should not be listed here. Routes should appear as "NC x", Interstates should appear as "I-x". If a route that runs parallel to the article route has four junctions or more with the article route, then only the first and last junctions with the parallel route should be listed in the infobox.
 * direction_b: The opposite of direction_a
 * ending_terminus: where the route ends, in accordance with the guidelines set forth with starting_terminus
 * counties: Comma-separated, wikified list of counties the route travels through, starting in the south or west. Limit of ten counties. Format the links so that only the county name is displayed.
 * cities: Comma-separated, wikified list of major cities the route travels through, starting in the south or west. Limit of ten cities. Format the links so that only the city name is displayed.
 * What is a major city?
 * Notable commercial center for region (important cities, towns, villages)
 * Large cities with a population over 20,000.
 * Less than seven cities total on route, but route serves as main street as opposed to just touching city limits.
 * County seats should always, always, always be included.
 * Minor towns, cities and villages if the route is short (less than 3 counties long)
 * Unincorporated communities only if the route is extremely short.
 * A mix of cities, towns, villages, and unincorporated communities can be found on the North Carolina Highway 12 article. There, all the major municipalties along the north section of the route are listed along with the distant unincorporated "commercial center" communities in the southern Outer Banks.
 * prev_type: This is the type of route that precedes the current one in the system. The value for this is: Interstate, US, or NC for Interstates, U.S. Routes and other NC highways, respectively.
 * prev_route: The number of the route preceding this one
 * next_type: Same as previous_type but for the route following this one
 * next_route: The number of the route succeeding this one
 * spur_type: For bannered or suffixed routes, the type of route that the parent route is.
 * spur_of: For bannered or suffixed routes, the number of the parent route.
 * browse: Use to add additional browse rows.
 * commons: Use to add a link to a category or gallery on Wikimedia Commons.
