Road
* Many roads are under water at levels which are potentially dangerous

  - visual representation of how government is able to perform
  - also a leading cause of forest fragmentation, one of the deadliest threats to wildlife
  - an integral part of leisure and amenity access for people
  - anchorages
  - believed to be a major contributing factor to the ongoing spread of exotic plants
  - capital, and they are generally cited as an important proximate cause of deforestation
  - for transportation as they have been for thousands of years
  - gravel and can become rough and muddy after rains
  - hard surfaces which increases the likelihood of stress problems
  - highly influential forces affecting ecological systems
  - less slippery when it's cold
* are located in bridges
  - maps
  - roadblock
  - towns
  - valleys
  - material goods that cost real resources to construct, operate, and maintain
* are one of the most prominent threats to turtles
  - significant causes of increased erosion
  - part of an overall transport system
  - paved surfaces
  - privates
  - rivers of erosion
  - roads, but there are hundreds of different plants
  - space dedicated above all to movement
  - the arteries of life
* are the greatest current threat to the continued existence of life on Earth
  - source of environmental degradation on the national forest system
  - most important mode of domestic freight and passenger transport
  - number one water quality concern in forests
  - oldest, most important infrastructure services provided by governments
  - only place bicycle riding can happen
  - transport system which allows materials to be carried throughout the city
  - to forests as borer is to wood
* are used for crosses
  - travelers
  - vital to keeps workers and goods flowing to areas where they are needed
  - vulnerable to things like ice storms
* block migration routes, cut off wildlife from food sources and otherwise fragment habitat.
* bring bears into conflict with people
  - people, and people bring non-native species of predators
* can also be a conduit for pollutants into the environment.
* can also cause floods, environmentalists charge
  - rapid mass movements and result in very large increases in sediment loads
  - have a direct impact on salmon
  - impede important animal migration
* can be dangerous places to work
  - nasty when it rains or snows
  - very destructive to arroyo toads and their habitat both in streams and in upland areas
* can become impassable in wet weather and conditions can change quickly
  - quite slick upon the first onset of rain
  - cause landslides, erosion, and siltation of streams
  - change the direction of natural water flow, affecting the way wetlands function
  - change, or introduce human uses that change, forest biodiversity
* cause direct mortality of many species and modify animal behavior
* constantly change camber as well as going up and down.
* define a city or region.
* deteriorate much faster when water has penetrated their surface.
* determine the basic form of any city.
* displace and fragment or isolate wildlife habitat.
* disrupt wildlife territories, movement, and migration patterns.
* disturb animal movement and migration patterns
* do immense damage to ecosystems, causing severe erosion and siltation of streams.
* encourage development.
* facilitate the invasion of weeds, which can force out native species of plants.
* free database, search and indexing system designed initially for Web cataloguing.
* frequently generate overland flow from relatively impermeable running surfaces and cutslopes.
* have capability
  - important economic and military functions
  - limits
  - markers
  - mileage markers
  - severe impact
  - speed limits
* includes readsides.
* includes safety islands
  - isles
  - zones
* includes traffic circles
* increase human use.
* is an artifact
  - the well traveled road that crosses the Continental Divide at Logans Pass
* lighting in cities is inadequate at best and nonexistent outside of cities.
* make interior forests accessible, exposing wildlife to increased mortality risks
  - it possible for the animals to move easily between feeding areas in winters of deep snow
* mean visibility, and visibility means death.
* open forest areas to development, erosion and pollution.
* prevent water from seeping into the ground.
* provide access for people to study, enjoy, or contemplate natural ecosystems
  - dependable pathways for moving people and goods from one place to another
* quickly become lakes, and the sides of mountains suddenly drop in avalanches of mud.
* resurfacing involves overlaying the road with a layer of asphalt.
* running participant oriented rather then spectator sport.
* serve as barriers, confining many species of wildlife within restricted areas.
* take up valuable land, reduce wildlife habitat and deprive the human community of open space.
* usually wind their way up or down in serpentines.
+ Bangui, Transportation: Capital cities in Africa :: Central African Republic
  * Bangui is a river port. It is served by Bangui M'Poko International Airport. The port handles the most of the country's trade with other countries. River ferries sail to Brazzaville and Zongo. Roads connect the city to Cameroon, Chad, and Sudan.
+ Bastide, Structural elements, Central square: History of France
  * All roads run in one direction and are parallel. Here and there there are alleys cut between the roads. The square is placed between two roads. These squares are usually  to  on each side.
+ Cassowary, Saving the cassowary: Birds of Australia :: Ratites :: Endangered species :: Flightless birds :: Struthioniformes
  * Road sign to protect cassowaries.
+ Controlled-access highway
  * These kinds of highways have four lanes or more. They carry many vehicles. They have no traffic-lights or ground level intersections. All roads crossing the highway go over a bridge or a tunnel. Ramps connect the highways to smaller roads and other highways. The place where highways meet these roads are called interchanges. Places where cars can leave or enter the motorway are called exits. Many freeways do not allow slower traffic, such as bicycles and pedestrians, to enter them.
+ Gettysburg, Pennsylvania: County seats in Pennsylvania
  * Many roads come from Gettysburg. Gettysburg Regional Airport, a small general aviation airport, is  west of Gettysburg. Gettysburg has weather that changes from around  in the winter months to almost  in the summer.
+ Greater Noida, History: Towns in India :: Uttar Pradesh
  * The government of Uttar Pradesh decided to incorporate the city of Greater Noida. This would be an extension to Noida. The planning of Greater Noida would be improved from what was learned in Noida. Greater Noida is a planned township. Roads are wide with service lanes for every major road. All cabling and utilities are run underground.
  * Road building and care is usually paid for by taxes. Some roads have tolls, where people pay to use the road.
