What is Highway Engineering?
Highway engineering is a civil engineering field dealing with the planning, designing, construction, operation, and maintenance of road networks. It deals with functional design as well as structural soundness, which means that the roads are designed to perform as per the requirements of performance, safety, and sustainability.
Highway engineering includes:
- Geometrical and alignment design of roads
- Ensuring effective drainage and slope management
- Selecting pavement materials and construction methods
- Traffic control measures integration
- Monitoring long-term durability and rehabilitation
Highway engineers also evaluate topography, weather, soil stability, environmental influences, and cost-effectiveness before deciding the most economical alignment of roads as well as the mode of construction.
What Does a Highway Engineer Do?
The question of what a highway engineer does is engaged in a huge field of work. Such professionals take part in all stages of a project cycle, including pre-feasibility, during construction, and post-construction maintenance.
1. Planning & Feasibility
- Conduct topographic and geotechnical surveys
- Conduct traffic projections, traffic accident statistics, and land usage.
- Evaluate environmental and social impact
- Provide estimations and alternatives.
2. Design & Engineering
- Develop road alignment (horizontal and vertical profiles)
- Embankments, intersections, retaining walls, and planned drainage
- Design cross-sections, medians, shoulders, and sidewalks
- Integrate road safety tests and road sign plans
3. Project Execution & Construction
- Draw tender plans and technical records
- Supervise contractors and coordinate with field teams
- Inspect material quality, specifications, and deadlines.
- Monitor roadbed compaction, pavement laying, and structural work
4. Post-Construction Services
- Conduct road surveys
- Recommend repairs, resurfacing, or full-depth reclamation
- Recommend best practice road technology (ITS, sensors, lighting)
- Support road expansion, tolling, or lane additions
These are just some of the highway engineer work responsibilities that highlight the role’s versatility and importance in long-term infrastructure development.
Key Skills Required To Become a Highway Engineer
Success in highway engineering depends not only on technical knowledge but also on critical soft skills and adaptability. Let’s break down the skills of a highway engineer across both domains.
Technical Skills
- Geometric Design: Involves planning road curves, super-elevations, slopes, and clear zones to ensure safe vehicle navigation and optimal visibility.
- Drainage Engineering: Focuses on designing culverts, open channels, and stormwater systems to prevent waterlogging and maintain road durability and safety.
- Pavement Design: Involves load assessment, choosing suitable materials, and layering to ensure long-lasting, cost-effective road surfaces under varying traffic conditions.
- Traffic Flow Simulation: Utilizes advanced software to simulate vehicle movements, analyze signal timings, and evaluate safety measures for smooth traffic operations.
- Surveying & GIS: Combines terrain mapping, contour analysis, and spatial data to support highway layout, alignment, and environmental impact studies.
- Code Knowledge: Requires familiarity with global and national standards like AASHTO, IRC, and ASTM for compliant and efficient road infrastructure design.
Engineers must also stay updated with innovations in 3D highway engineering, particularly when working on large-scale urban corridors.
Soft Skills
- Project Management: Balancing time, scope, cost, and manpower
- Communication: Conveying complex designs to clients, teams, and government agencies
- Problem Solving: Adapting plans based on site realities or stakeholder input
- Team Collaboration: Coordinating across departments—geotech, structures, environment, and traffic
If you’re just starting out, cultivating the skills of entry level highway engineer roles across both technical and interpersonal domains is essential for growth.
Most Used Highway Engineering Software
The digital revolution has completely reshaped how engineers approach design and execution. Here are the top five best highway engineering software used by professionals worldwide, all of which support more efficient, accurate, and collaborative work:
1. Autodesk Civil 3D
Autodesk Civil 3D is the industry standard for 3D highway engineering. It facilitates corridor modeling, cross-sections, grading plans, earthworks volumes, and pipe networks. It allows engineers to optimize the workflow and ensure no margin of error, even in the construction documentation stage of road design.
2. Bentley OpenRoads Designer
Bentley OpenRoads Designer comes in a BIM-ready environment that provides an integrated design of roads and drainage. It undertakes alignments, pavement layers, terrain modeling, and earthwork balancing. It is suitable for big infrastructures and facilitates teamwork and coordination among the teams, consultants, and the government.
3. Autodesk Revit
Autodesk Revit is a BIM coordination program that is used prominently in highway and infrastructure projects. It will enable them to create intelligent 3D models incorporating architectural, structural, and MEP disciplines, and coordination between disciplines will be a breeze.
For highway engineers, it is possible to model bridges, road-related structural detailing, and connect to civil software such as InfraWorks and Civil 3D, which Revit does, making the BIM coordination process much more straightforward.
4. Tekla Structures
Tekla Structures is a strong 3D BIM coordination software mainly utilized in detailed structural modeling. It is used in highway construction, including bridges, retaining walls, and pre-cast items.
The ability to perform precision model analysis and constructability verification makes it among the best tools in BIM coordination for detecting clashes, estimating quantities, and detailing rebars in complex infrastructure arrangements.
5. ArcGIS Pro
ArcGIS Pro is an essential geospatial highway planning and feasibility study instrument. It uses spatial data and overlays environmental, social, and regulatory layers to aid in route choice. Engineers use it to visualise restrictions, facilitate the public's consultation, and optimise road routes through complicated considerations and meanings.
Each of these tools forms part of the essential software used in highway engineering, and professionals are often expected to be proficient in two or more of them.
