As civil engineers, when we build a road or a bridge, we always think about the people who will use it, the communities that rely on these infrastructures daily to get to work, school, or transport goods. Every project has a direct impact on daily life, and we understand that. That’s why, at Dromcons, we commit to building to the highest execution standards so these communities can enjoy a better future.

For roads and bridges to stand the test of time and meet the real needs of users, the first step – road and bridge design – must be carried out at the highest level of professionalism. A well-thought-out design becomes the blueprint for construction teams, so it’s crucial to ensure it’s done correctly to achieve a durable and long-lasting result.

If you own a construction company or are a private investor interested in road or bridge projects, keep reading to find out how we can help you with your project.

What Does Road and Bridge Design Involve?

Road infrastructure design is a complex process that combines multiple fields: engineering, legislation, environmental studies, and economics. Each road and bridge directly impacts the community and must be considered as part of a larger system. A technical project for roads and bridges goes through several stages, including:

  • Feasibility Study – This answers the question: “Is it worth building here?” Costs, environmental impact, and social benefits are analyzed to determine whether the project is technically and economically feasible.
  • Topographic Surveys – At this stage, the land is measured in detail. State-of-the-art equipment creates precise 3D models of the area, helping to define the optimal route.
  • Obtaining Permits and Approvals – These documents are mandatory to start construction. The Dromcons team handles all the bureaucracy, so you don’t have to.
  • Technical Design and Execution Details – Here, the concrete elements are defined: road structure, foundation type, asphalt layer thickness, bridge structure, and more.


For example, for an access road in a new residential area, engineers first conduct topographic surveys, propose the optimal route, calculate slopes, and determine the type of pavement required for the expected traffic.


Road Design – Safety and Efficiency

A properly designed road immediately improves the driver experience. This translates into safety, durability, and reduced maintenance costs. During the design phase, several plans must be developed, each playing a critical role:

  • Longitudinal and Cross Profiles

    • Longitudinal Profile – Shows the road’s gradient and height relative to the terrain. Excessive slopes can cause difficulties for heavy vehicles.

    • Cross Profile – Shows the road structure across its width, including lanes, shoulders, sidewalks, and drainage systems. Poor cross-slope design can lead to water accumulation and increased accident risk.

  • Route Optimization for Costs and Environment

    • Cost Reduction – Selecting the most efficient route.

    • Environmental Protection – Avoiding sensitive natural areas or unstable land.

At Dromcons, every road design project also includes:

  • Site Plan – Shows the exact road placement relative to the terrain and existing infrastructure.

  • Zoning Integration Plan – Demonstrates that the new construction complies with urban regulations and integrates harmoniously with the landscape.


Over the years, Dromcons has participated in various road infrastructure projects, such as the East Arad Bypass – approximately 11 km of road, 7 intersections, and multiple auxiliary works.


Bridge Design – Engineering and Durability

Bridges are true engineering symbols. Beyond their practical purpose – spanning rivers or valleys – they add aesthetic value to their surroundings. At Dromcons, we provide complete bridge design services, considering key aspects:

  • Structural Calculations and Material Selection

    • Structural Calculations – Analyze all possible loads: the bridge’s weight, daily traffic, and natural factors like wind or earthquakes.

    • Material Selection – Crucial for the construction’s lifespan. Reinforced concrete is highly durable, steel allows large spans, and modern composites offer reduced weight and corrosion resistance.

  • Benefits of an Optimized Design

    • Maximum safety – Structures withstand natural factors and heavy loads.

    • Economic efficiency – Reduced costs with the right technical solutions.

    • Durability – Minimal long-term maintenance.

    • Aesthetic integration – Bridges that harmonize with urban or natural landscapes.

At Dromcons, we rigorously follow each stage so the benefits are evident in every bridge project we undertake.

Case Studies – Roads and Bridges Designed by Dromcons

  1. East Arad Bypass
    In collaboration with SC PORR Construct SRL for the Arad County Council and CNAIR. Designed 11 km of road, 7 intersections, conducted 75 geotechnical drillings, and completed all topographic studies and permits.

  2. Oradea Metropolitan Ring Road
    For Bihor County Council: designed 8 km of road and 3 intersections. Conducted 51 geotechnical drillings up to 25 m deep, detailed topographic studies, and provided technical support throughout construction.

  3. Bridge on DN14A Blăjel
    In partnership with GEIGER Transilvania SRL: modernized the bridge with shallow and medium-depth drillings, dynamic penetration tests, topographic studies, and a complete technical project.

  4. A13 Highway – Sibiu-Făgăraș
    In partnership with MAKYOL Istanbul: contributed with complex geotechnical investigations, including drillings up to 80 m, penetration tests, mapping, and detailed soil and water analyses.
