| Engineer | Professionals who invent, design, analyze, build and test machines, complex systems, structures, . |
| Civil Engineer | Conceive, design, build, supervise, operate, construct and maintain infrastructure projects and systems in the public and private sector, including roads, buildings. |
| Hydraulic Engineer | The application of fluid mechanics to water flowing in an isolated environment (pipe, pump) or in an open channel (river, lake, ocean). |
| Geotechnical Engineer | Investigate and evaluate soil, rock, groundwater, and man-made materials and their interaction with earth retention systems, structure foundations, |
| Structural Engineer | Create drawings and specifications, perform calculations, review the work of other engineers, write reports and evaluations, and observe construction sites. |
| Abutment | are the elements at the ends of a bridge that support it. |
| Arch | is a curved structure that spans an open space. Bridges using arches were among the earliest large-scale engineering and construction projects. Can span vast areas. |
| Beam | A long, rigid horizontal support part of a structure. |
| Bent | This is the combination of the cap and the pile. Together, with other bents, they act as support for the entire bridge. |
| Bridge | A structure built for vehicles or persons to cross over a road, railway, or water channel. |
| Column | A long, rigid, vertical (upright) support part of the structure. |
| Deck | The surface of a bridge where vehicles travel. They’re generally covered with asphalt, concrete, or some other type of pavement. |
| Foundation | The foundation (or base) of a bridge is the element that connects the structure to the earth and transfers loads from it to the ground below. |
| Girder | A rigid horizontal structure and two supports, one at each end, to rest it on. These components directly support the downward weight of the bridge and any traffic traveling over it. |
| Span | The length of the bridge from one pier to another. |
| Truss | Part of the structure frame based on the geometry of the strength of the triangle. |
| Superstructure | The part of the bridge that absorbs the live load. (The abutment, piers, and other support elements |
| Pier | Is a raised structure that sits in a body of water to support a bridge. |
| Pile | Is a vertical support structure that’s used, in part, to hold up a bridge. |
| Bearing | Provides a resting surface between the piers of a bridge and its deck. |
