Template:Routelist top/doc

This template creates a heading for a standard U.S. highway list. Use it in conjunction with routelist row and routelist bottom to create a table of highway routes.

Usage

 * 1: if local, a "Local names" column will be included after the terminus columns. If county, a "Counties" column will be included after the terminus columns.
 * length_ref: a reference for the length of all routes in the table. The reference will be placed next to the appropriate "Length" heading. If different references are used for different routes, use the  parameter of each instance of routelist row instead.
 * notes: if no, the "Notes" column will be omitted.
 * caption: if present, will add a caption to the table; if it would duplicate a nearby section header, can be restricted to screen-reader software using the sronly template
