INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
SEST involved the construction of 25 km of motorway approximately 300 metres in width and with 6 lanes, three in each direction. In turn, the project had nine links, an elevated section in some portions and 27 structures.
The 27 structures that are part of the project had a total length of almost 2 kilometres, allowing the continuity of the motorway. Likewise, 11 very important junctions were built.
Conservation of the ecosystem was a key factor during all phases of construction, as was having no impact on the species in the area and the Athabasca River.
The new construction section had the following characteristics:
- 25 km of 6 lanes (3+3).
- Section width of almost 300 metres.
- 27 structures (bridges and overpasses).
GENERAL INFORMATION
- Location: Calgary, Alberta, Canada.
- Contract type: Design, construction, financing, operation and maintenance (PPP).
- Infrastructure: 25 kilometres of a 6-lane road, 3 km of pedestrian paths, 27 new bridge structures, including bridges over railway lines, and 11 intersections.
- Year of project completion: 2013
SOCIAL INITIATIVES
Calgary residents will enjoy a great benefit as a result of this part of the bypass, not to mention the great impact that it will have on our transport and logistics industries to be able to move their products faster and more efficiently.

Tecnology and innovation
sustainable innovation
A number of innovative practices were used at the South East Stoney Trail Project to reduce the carbon footprint of the road construction and increase the sustainability of new road infrastructure.
For example, all earth-moving material will be sourced on site, with a total of 12.4 million m3 of excavation to be used as landfill. In addition, existing junctions will become grade-separated interchanges without signals, which will increase the free flow of traffic by significantly reducing engine idling, especially in heavy diesel lorries. Our sustainable construction practices reduce the movement of goods to and from the site, improving efficiency, reducing transportation, fuel costs and emissions, and ultimately providing a more economical solution.
The technical complexity of the project is due to:
- Planning and coordination for the scale of earthwork and paving involved.
- Optimize design and construction activities.
- Work in sensitive saline wetlands and within environmental schedule restriction windows.
- Work safely on and around existing roads.
- Operate and maintain the existing road during construction work.
