Sorts of Structure (notwithstanding Models)


The maintenance of large-scale, high-volume bridges is necessary for many people’s daily transit. Examples of bridge infrastructure include:

  • Beam bridges
  • Cable bridges
  • Arch bridges

Power and energy

Traditional energy infrastructures include coal, gas and nuclear plants, which help produce electricity for the entire country. Maintenance crews regularly perform repairs and maintenance on the plants to ensure they properly and efficiently transmit power to the correct locations. Modern infrastructure projects create power and store energy without the use of fossil fuels, such as solar-, wind- and geothermal-powered infrastructures.

A few examples of both traditional and renewable energy infrastructures used today are:

  • Electric power grid networks
  • Nuclear plants
  • Gas pipelines
  • Fossil fuel-based power production such as gas and coal plants
  • Renewable energy like hydro-electric power, biofuels and solar power


In addition to train tracks, railroad infrastructure includes all buildings, equipment and land that support the railways. This also includes management, transport of materials and maintenance of rail lines and all of their facilities. Divided into two categories, the rail network consists of freight and passenger. For both categories, railroad infrastructure projects involve the maintenance and upkeep of the current railways, but also include making efforts to create new rail line extensions and adding signage near railways.

Examples of railway infrastructures include:

  • Railway lines
  • Trains
  • Tunnels
  • Railroad bridges
  • Train stations


Roadway infrastructure includes drivable locations such as highways, roads and streets. Minor roadway projects are tasks such as creating new traffic lights, signage, ramps and traffic lanes. Larger roadway projects consist of building new roads and repairing existing roads. Street and highway reconstruction and resurfacing are essential to keeping a road in drivable condition. Many states rely on the income from toll roads to fund the construction.

Some examples of roadway infrastructures include:

  • Roads
  • Bridges
  • Tunnels
  • Bus transit


The constant supply of clean and filtered water to people across a country is an important infrastructure to maintain. Water infrastructure projects differ depending on location because of environmental factors. For example, in a location that typically has droughts, water infrastructure projects ensure the continuation of a steady water supply and reduce the number of leaks by monitoring and repairing the water facilities in use. Most projects include updating the current distribution of water and finding effective ways to transport water from one location to another.

Examples of water infrastructure include:

  • Main water lines
  • Wells
  • Pumping stations
  • Treatment plants
  • Septic tanks
  • Stormwater drains
  • Roadside gutters
  • Dams
  • Levees
