Editing Milestone (section)

== Modern highways ==
{{main article|Highway location marker}}
The historical term ''milestone'' is still used today, even though the "stones" are typically metal [[highway location marker]]s and in most countries use kilometres and metres rather than miles and yards. Also found today are more closely spaced signs containing fractional numbers, and signs along railways, beaches and canals.

=== Australia ===
{{unreferenced section|date=January 2020}}
[[Metrication in Australia]] caused the former mile markers to be gradually replaced with 10&nbsp;km markers on highways and country roads, which are referred to as "kilometre plates".

Kilometre plates have white text on a trapezoidal green background, and are generally located about a metre above the ground. They have a letter which indicates the town or city they are referring to, and a number, which is the distance in kilometres to that town or city.

Kilometre plates are now generally 5&nbsp;km apart on major highways and 10 or 20&nbsp;km apart on less popular or rural highways, though there are many exceptions. Kilometre plates are supplemented by signboards, which display distances to several towns ahead.

Some mile markers are retained as curiosities (see gallery). These include stone markers on Victoria's Glenelg Highway at Delacombe,

=== Canada ===
Usage varies by province, as highways are under provincial jurisdiction. In Alberta, for example, kilometre markers are green metal signs with white lettering, and are generally placed every 4&nbsp;km starting at the last major intersection to the south or west, depending on whether the route runs north–south or east–west.

=== India ===
[[File:Road Stone Payyambalam.jpg|thumbnail|Milestone in Payyambalam beach, [[Kannur]], India.]]
Milestones on [[National highways of India]] typically have white backgrounds with yellow tops (on national highways) or green tops (on state highways). The names of cities and distances are painted in black. The names of the nearest towns and cities are written along with distance in kilometres. On undivided highways, both sides of the milestones are used, telling the distance to the nearest cities in each direction. The highway number is written on the head of the milestone. The sum of the distances of two nearest cities in each direction from the milestone is listed on the side.

=== Philippines ===
[[File:Philippine highway marker.jpg|thumb|Example of a milestone in the Philippines]]
Milestones in the Philippines are found in [[Highways in the Philippines|highways]], one kilometer apart, and are found in pairs, one on each side of the road. These are short yellow concrete posts, with two labels on a white background, written in black. On top is a large "K" (or "KM"), and a number, referencing the distance from the [[Kilometre Zero#Philippines|kilometre zero]]. While the national kilometre zero is in [[Rizal Park]], each major island has its own kilometre zero. The milestones on the [[Luzon]] mainland reference Rizal Park's kilometre zero.

The second label is a letter, standing for the first letter of the next town if one is traveling on ''that'' direction, then the distance in kilometers, from the town. In the example to the right, a milestone in [[Ortigas Avenue]] in [[Pasig]] says it is {{convert|14|km|mi|sp=us}} from Rizal Park, and {{convert|3|km|mi|sp=us}} from [[Cainta]]. On the other side, the milestone there says it is 
{{convert|2|km|mi|sp=us}} from [[San Juan, Metro Manila|San Juan]].

Most milestones only have labels on one side, facing the driver. Others have labels on all four sides.

=== United Kingdom ===
{{Main article|Driver location sign}}
In the UK, [[driver location signs]] are placed every {{convert|500|m|yd}} along each side of [[List of motorways in the United Kingdom|motorways]], and along some other major roads. They were first introduced in 2003, and they complement distance marker posts, small roadside posts at {{convert|100|m|yd}} intervals, used for road maintenance and administrative purposes. Both types of sign display a unique location number. The number is given without units but is the distance in kilometres from a designated datum location for the road.<ref name=faq>{{cite web |url = http://www.highways.gov.uk/business/16049.htm |archive-url = http://webarchive.nationalarchives.gov.uk/20120810121037/http://www.highways.gov.uk/business/16049.htm |url-status = dead |archive-date = 10 August 2012 |title = Driver Location Signs - Frequently Asked Questions |author = Highways Agency |author-link = Highways Agency |access-date = 2010-02-10 }}</ref>

[[File:Intersection of the Bypass Highway and Van Giesen Street 6.jpg|thumb|Typical mile marker used in the United States]]
In the U.S. [[Interstate Highway System]], the numbers usually measure the distance to the southern or western [[U.S. state|state]] line, or the route's terminus, if the national southern or western terminus lies in that state. The numbering system for other [[highway]]s varies by state; most use a system mirroring that of the Interstate System, other states, such as [[Illinois]], [[California]], and [[Kentucky]], use the [[county]] line as the [[zero mile marker]], while others, including [[Missouri]], do not sign mile-markers at all (except on Interstates). [[Arizona]] has a rather unusual system, where a route's mileposts continue those from its original host. Often, the [[interchange (road)#Terminology|exits]] are numbered according to the nearest milepost, known as the [[mile-log#Distance-based numbers|mile-log]] system.  From the beginning of the Interstate system until the mid-2000s, most Interstate highways had markers every mile.  Since that time, many states have installed more markers every 0.25 mile, every 0.2 mile, or in some metro areas, every 0.1 mile.  Some historic and [[scenic route]]s – such as along the [[Blue Ridge Parkway]] in [[North Carolina]] and [[Virginia]] and the [[Overseas Highway]] of the [[Florida Keys]] – use mileposts to mark points of interest or (in the cases of many businesses along the Overseas Highway) as a portion of their address.

In [[Myanmar]], [[furlong]]s have been used at least until 2010 in conjunction with miles to indicate distances on highway signs, for example on the [[Yangon-Mandalay Expressway]].

=== Zimbabwe ===
[[Zimbabwean]] milestones are constructed of cast concrete painted white with the kilometre distance indented and painted black.<ref>{{cite web

There is no distinction between state and national road-sign markings. They were originally sited every 500 metres by the [[Rhodesian]] Ministry of Roads and Road Traffic, starting at zero from the largest town or city. In 1980, the Zimbabwean government began placing new markers 1&nbsp;km apart and damaged or missing half kilometre markers were no longer replaced.
