Peab has secured a contract valued at Skr2.2bn ($219m) from the Swedish Transport Administration to build the E22 Söderköping bypass located in Östergötland County, Sweden.
The project, which is scheduled to open to traffic in the summer of 2030, marks the first time an alliance contract has been used in Sweden’s civil engineering sector.

The bypass, stretching slightly more than 10km, will reroute through traffic along the E22 to the southwest of Söderköping.
The construction will include a central guardrail to improve safety, along with four interchanges and 12 bridges.
A key element of the project is a new aqueduct on the Göta Canal, allowing the E22 to pass beneath the canal and enabling uninterrupted road and waterway traffic.
Under the alliance model, Peab, the Swedish Transport Administration, and ELU Konsult will share responsibilities within a single joint organisation.
The collaborative approach encompasses all project phases, including design, planning and execution.
Peab region manager Mattias Emanuelsson said: “Peab is very proud to be able to put the alliance model into practice together with the Swedish Transport Administration and demonstrate how powerful close collaboration can be when it starts near the beginning of a project.
“By working as a team we’re creating the right conditions for efficient production, high quality and successful implementation.”
According to Peab, the model aims to enhance delivery capacity, strengthen cost management and promote transparency throughout the project.
Swedish Transport Administration Southeast Region regional director Peter Bernström said: “The Swedish Transport Administration is undergoing a transition process in order to become a more efficient and responsive administration.
“The Söderköping Bypass is one of the projects where we are challenging how we design, plan and build infrastructure, in immersed and close collaboration with the industry – in an alliance.”
Work on the bypass is set to commence immediately.
The contract will be recorded in Peab’s Civil Engineering business area in the fourth quarter of 2026.
In September 2025, Peab was awarded a contract to build a new campus for Hitachi Energy in Finnslätten, Västerås, Sweden.
