A milestone is a numbered marker placed on a route such as a road, railway line, canal or boundary. They can indicate the distance to towns, cities, and other places or landmarks like mileage signs; or they can give their position on the route relative to some datum location. On roads they are typically located at the side or in a median or central reservation. They are alternatively known as mile markers, mileposts or mile posts. A "kilometric point" is a term used in metricated areas, where distances are commonly measured in kilometres instead of miles. "Distance marker" is a generic unit-agnostic term.
An exit number is a number assigned to a road junction, usually an exit from a freeway. It is usually marked on the same sign as the destinations of the exit. In some countries, such as the United States, it is also marked on a sign in the gore.
State Route 58 is a major east-west state highway in the U.S. state of California that runs across the Coast Ranges, the southern San Joaquin Valley, the Tehachapi Mountains, which border the southern Sierra Nevada, and the Mojave Desert. It runs between U.S. Route 101 near Santa Margarita and Interstate 15 in Barstow. It has junctions with Interstate 5 near Buttonwillow, State Route 99 in Bakersfield, State Route 202 in Tehachapi, State Route 14 near Mojave, and U.S. Route 395 at Kramer Junction. SR 58 also provides access to Edwards Air Force Base. At various points it is known as the Calf Canyon Highway, Carrisa Highway, Bakersfield-McKittrick Highway, Rosa Parks Highway, Westside Parkway, Barstow-Bakersfield Highway, Bakersfield Tehachapi Highway, Kern County Korean War Veterans Memorial Highway, and Mojave-Barstow Highway.
State Route 99 (SR 99) is a north–south state highway in the U.S. state of California, stretching almost the entire length of the Central Valley. From its southern end at Interstate 5 (I-5) near Wheeler Ridge to its northern end at SR 36 near Red Bluff, SR 99 goes through the densely populated eastern parts of the valley. Cities served include Bakersfield, Delano, Tulare, Visalia, Fresno, Madera, Merced, Turlock, Modesto, Manteca, Stockton, Sacramento, Yuba City, and Chico.
State Route 126 is a state highway in the U.S. state of California that serves Ventura and Los Angeles counties. The route runs from U.S. Route 101 in Ventura to Interstate 5 at the Castaic Junction-Santa Clarita border through the Santa Clara River Valley. The highway is an important connector highway in Ventura County, and serves as an alternate route into the Santa Clarita Valley, and the San Fernando Valley area of Los Angeles and the High Desert of Antelope Valley.
Interstate 684 (I-684) is a 28.47-mile (45.82 km) auxiliary Interstate Highway in the state of New York in the United States. There is also a short portion in Connecticut with no junctions. The highway connects I-84 with I-287 and the Hutchinson River Parkway, primarily serving commuter traffic to and from the northern suburbs of the New York metropolitan area. Most of the route is in northern Westchester County. The route of the highway was originally designated as part of I-87 from 1968 to 1970. The first section of the roadway opened to traffic in October 1968, and the final segment was completed in December 1974.
State Route 299 is an east–west state highway in the U.S. state of California that runs across the northern part of the state. At 305.777 miles (492.100 km), it is the third longest California state route, after Route 1 and Route 99, and the longest east-west route. Route 299's western terminus is at US 101 at the northern edge of Arcata, and its eastern terminus is at the Nevada state line at a point east of Cedarville. Between Arcata and Redding, Route 299 intersects with State Route 96, and is briefly co-signed with State Route 3. In Redding, it intersects with State Route 273, State Route 44, and Interstate 5. East of Redding, it intersects with State Route 89, and a section is co-signed with State Route 139 before reaching Alturas. It is then co-signed with U.S. Route 395 northeast of Alturas, and then runs east through Cedarville and to the border with Nevada. A ghost town, Vya, Nevada, can be reached via this route, which after the border becomes a dirt road, which was formerly Nevada State Route 8A. The segment of SR 299 between Arcata and Redding is the Trinity Scenic Byway, a National Forest Scenic Byway.
State Route 41 is a state highway in the U.S. State of California, connecting the Central Coast with the San Joaquin Valley and the Sierra Nevada. Its southern terminus is at the Cabrillo Highway in Morro Bay, and its northern terminus is at SR 140 in Yosemite National Park. It has been constructed as an expressway from near SR 198 in Lemoore north to the south part of Fresno, where the Yosemite Freeway begins, passing along the east side of downtown and extending north into Madera County.
A control city is a city, locality, or other location posted on a series of traffic signs along a particular stretch of road indicating destinations on that route. Together with route numbers and cardinal directions, these focal points aid the motorist navigating along a highway system. Such cities appear on signs at junctions to indicate where the intersecting road goes and where the road ahead goes. They are also typically used on distance signs.
Road signs in the United Kingdom and in its associated Crown dependencies and overseas territories conform broadly to European design norms, though a number of signs are unique: direction signs omit European route numbers, and road signs generally use the imperial system of units, unlike the rest of Europe. Signs in Wales and parts of Scotland are bilingual.
State Route 89 is a state highway in the U.S. state of California that travels in the north–south direction, serving as a major thoroughfare for many mountain communities in the Sierra Nevada and the Cascade Range. It starts from U.S. Route 395 near Topaz Lake, winding its way up to the 8,314-foot (2,534 m) Monitor Pass, down to the Carson River, and up again over the 7,740-foot (2,359 m) Luther Pass. From that point on, the route generally loses elevation on its way past Lake Tahoe, through Tahoe and Plumas National Forests until Lake Almanor. For roughly nine miles the route is then a part of State Route 36. The route then ascends to the 5,753-foot (1,754 m) Morgan Summit. After it enters Lassen Volcanic National Park it continues to gain elevation until it reaches its highest point in an unnamed pass in the middle of Lassen Peak and Bumpass Mountain. The road then descends and heads northwest, finally terminating at Interstate 5 at the foot of Mount Shasta at around 3,600 feet (1,100 m).
A gantry is a traffic sign assembly in which signs are mounted or railway signals are supported on an overhead support. They also often contain the apparatus for traffic monitoring systems and cameras, or open road tolling systems.
Road signs in Malaysia are standardised road signs similar to those used in Europe but with certain distinctions. Until the early 1980s, Malaysia closely practice in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Signs usually use the Transport Heavy font on non-tolled roads and highways. Tolled expressways signs use a font specially designed for the Malaysian Highway Authority (LLM) which is LLM Lettering. It has two type of typefaces, LLM Narrow and LLM Normal. Older road signs used the FHWA Series fonts typeface also used in the United States, Canada, and Australia.
Exit numbers in the United States are assigned to freeway junctions, and are usually numbered as exits from freeways. Exit numbers generally are found above the destinations and route number(s) at the exit, as well as a sign in the gore. Exit numbers typically reset at political borders such as state lines. Some major streets also use exit numbers. Freeway exits in the United States are usually numbered in two formats: distance-based and sequential.
California uses a postmile highway location marker system on all of its state highways, including U.S. Routes and Interstate Highways. The postmile markers indicate the distance a route travels through individual counties, as opposed to milestones that indicate the distance traveled through a state. The postmile system is the only route reference system used by the California Department of Transportation (Caltrans). The system was operative by 1966.
U.S. Route 95 (US 95) is a United States Numbered Highway, stretching from the Mexican border in San Luis, Arizona to the Canadian border near Eastport, Idaho. The California portion of US 95 traverses through the far eastern edges of both Riverside and San Bernardino counties. US 95 serves Blythe and Needles and junctions with SR 62 at Vidal Junction.
A highway location marker is the modern-day equivalent of a milestone. Unlike traditional milestones, however, which were originally carved from stone and sited at one-mile intervals, modern highway location markers are made from a variety of materials and are almost invariably spaced at intervals of a kilometre or a fraction thereof. In some countries they may be known as driver location signs, milestones or kilometre stones.
Driver location signs are signs placed every 500 metres (550 yd) along each side of English motorways, and some other major English roads, to provide information that will allow motorists to know their precise location. As of July 2009, roads in England, but not Scotland, Wales or Northern Ireland, have these signs. This information might be useful in the event of an emergency or breakdown. They were first introduced in 2003, and they complement distance marker posts. Both types of sign display a unique location number. The number, although given without units, is the distance in kilometres from a designated datum location for the road, although signs meant for driver navigation are in miles.
The road signs of the Kingdom of the Netherlands, as well as Suriname, are regulated in the Reglement verkeersregels en verkeerstekens 1990, commonly abbreviated as RVV 1990. While most previous signage, from the RVV 1966 (Dutch) remained legal and official, they have been updated / replaced. Some aren't official anymore and have lost legal validity, but most surviving old signs remained valid.
Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
