The map below shows the current status of park roads and road construction. Click on a road segment or icon for more information. Conditions can change quickly, so check back often. Short-term road closures and delays may not be shown.
The only road generally open year-round to regular vehicles is from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana (via Tower Junction). Most park roads are closed to regular vehicles from early November to late-April, and are open to limited oversnow travel (commercially-guided snowmobiles and snowcoaches) from mid-December to mid-March. When open, roads are not gated at night and people may enter/exit the park 24 hours a day, seven days a week.
Yellowstone has five entrance stations, and it takes several hours to drive between them. Anticipate possible road closures, and check the road status of the entrance you intend to use before traveling.
It's important to be aware of all planned road improvement projects, as they can cause major traffic delays throughout the park. Drive slowly through construction zones and be alert to workers, heavy equipment, wildlife, and other hazards. The following road improvement projects in Yellowstone will cause traffic delays:
Location: Near Tower Junction along the Northeast Entrance Road
Access: Expect up to 30-minute delays during 2024. Hiking trails in the area may close temporarily during the duration of the project (visit the Backcountry Situation Report for more details).
Improvements: This project began in 2023 and will conclude in fall 2026. It includes the replacement of the structurally deficient Yellowstone River Bridge originally built in 1961. A new 1,285-foot-long, 175-foot-high steel girder bridge upstream will replace the existing 604-foot-long bridge to preserve year-round access to/from the Northeast Entrance and communities of Silver Gate and Cooke City, Montana. New pullouts, paved parking areas, and dedicated route across the new bridge will increase access to trails, fishing, and viewpoints. Additionally, the Yellowstone River Picnic Area will be enlarged to accommodate increase visitor use.
Additionally, chip sealing occurs every summer and preserves Yellowstone's roads. Plan for delays of up to 30 minutes. Drive slowly and maintain the recommended speed limit on chip seal pavement to reduce the risk of loose gravel damaging cars or windshields.

A road is a thoroughfare for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, whose primary function is to serve as public spaces, the main function of roads is transportation.
The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which includes "bridges, tunnels, supporting structures, junctions, crossings, interchanges, and toll roads, but not cycle paths".[2]
The Eurostat, ITF and UNECE Glossary for Transport Statistics Illustrated defines a road as a "Line of communication (traveled way) open to public traffic, primarily for the use of road motor vehicles, using a stabilized base other than rails or air strips. [...] Included are paved roads and other roads with a stabilized base, e.g. gravel roads. Roads also cover streets, bridges, tunnels, supporting structures, junctions, crossings and interchanges. Toll roads are also included. Excluded are dedicated cycle lanes."[3]
In urban areas roads may diverge through a city or village and be named as streets, serving a dual function as urban space easement and route.[5] Modern roads are normally smoothed, paved, or otherwise prepared to allow easy travel.[6]
Further, it defines a shoulder (typical an area of the road outside the edge line, or the curb) and a road-related area which includes green areas separating roads, areas designated for cyclists and areas generally accessible to the public for driving, riding or parking vehicles.
In New Zealand, the definition of a road is broad in common law[8] where the statutory definition includes areas the public has access to, by right or not.[9] Beaches, publicly accessible car parks and yards (even if privately owned), river beds, road shoulders (verges), wharves and bridges are included.[10] However, the definition of a road for insurance purposes may be restricted to reduce risk.
In the United Kingdom The Highway Code details rules for "road users", but there is some ambiguity between the terms highway and road.[11] For the purposes of the English law, Highways Act 1980, which covers England and Wales but not Scotland or Northern Ireland, road is "any length of highway or of any other road to which the public has access, and includes bridges over which a road passes".[12] This includes footpaths, bridleways and cycle tracks, and also road and driveways on private land and many car parks.[13] Vehicle Excise Duty, a road use tax, is payable on some vehicles used on the public road.[13]
The definition of a road depends on the definition of a highway; there is no formal definition for a highway in the relevant Act. A 1984 ruling said "the land over which a public right of way exists is known as a highway; and although most highways have been made up into roads, and most easements of way exist over footpaths, the presence or absence of a made road has nothing to do with the distinction.[14][15] Another legal view is that while a highway historically included footpaths, bridleways, driftways, etc., it can now be used to mean those ways that allow the movement of motor vehicles, and the term rights of way can be used to cover the wider usage.[16]
The assertion that the first pathways were the trails made by animals has not been universally accepted; in many cases animals do not follow constant paths.[1] Some believe that some roads originated from following animal trails.[21][22] The Icknield Way may exemplify this type of road origination, where human and animal both selected the same natural line.[23] By about 10,000 BC human travelers used rough roads/pathways.[1]
Geosynthetics such as geotextiles, geogrids, and geocells are frequently used in the various pavement layers to improve road quality. These materials and methods are used in low-traffic private roadways as well as public roads and highways.[44] Geosynthetics perform four main functions in roads: separation, reinforcement, filtration, and drainage; which increase the pavement performance, reduce construction costs and decrease maintenance.[45][self-published source]
The completed roadway is finished by paving or left with a gravel or other natural surface. The type of road surface is dependent on economic factors and expected usage. Safety improvements such as traffic signs, crash barriers, raised pavement markers and other forms of road surface marking are installed.
When a single carriageway road is converted into dual carriageway by building a second separate carriageway alongside the first, it is usually referred to as duplication,[46] twinning or doubling. The original carriageway is changed from two-way to become one-way, while the new carriageway is one-way in the opposite direction. In the same way as converting railway lines from single track to double track, the new carriageway is not always constructed directly alongside the existing carriageway.
Roads that are intended for use by a particular mode of transport can be reallocated for another mode of transport,[47] i.e. by using traffic signs. For instance, in the ongoing road space reallocation effort, some roads (particularly in city centers) which are intended for use by cars are increasingly being repurposed for cycling and/or walking.[48][49][50]
Like all structures, roads deteriorate over time. Deterioration is primarily due to environmental effects such as frost heaves, thermal cracking and oxidation often contribute, however accumulated damage from vehicles also contributes.[51] According to a series of experiments carried out in the late 1950s, called the AASHO Road Test, it was empirically determined that the effective damage done to the road is roughly proportional to the fourth power of axle weight.[52] A typical tractor-trailer weighing 80,000 pounds (36.287 t) with 8,000 pounds (3.629 t) on the steer axle and 36,000 pounds (16.329 t) on both of the tandem axle groups is expected to do 7,800 times more damage than a passenger vehicle with 2,000 pounds (0.907 t) on each axle. Potholes on roads are caused by rain damage and vehicle braking or related construction work.
Pavements are designed for an expected service life or design life. In some parts of the United Kingdom the standard design life is 40 years for new bitumen and concrete pavement. Maintenance is considered in the whole life cost of the road with service at 10, 20 and 30-year milestones.[53] Roads can be and are designed for a variety of lives (8-, 15-, 30-, and 60-year designs). When pavement lasts longer than its intended life, it may have been overbuilt, and the original costs may have been too high. When a pavement fails before its intended design life, the owner may have excessive repair and rehabilitation costs. Some asphalt pavements are designed as perpetual pavements with an expected structural life in excess of 50 years.[54]
Many asphalt pavements built over 35 years ago, despite not being specifically designed as a perpetual pavement, have remained in good condition long past their design life.[55] Many concrete pavements built since the 1950s have significantly outlived their intended design lives.[56] Some roads like Chicago's Wacker Drive, a major two-level (and at one point, three-level) roadway in the downtown area, are being rebuilt with a designed service life of 100 years.[57]
