The main element of the project is the 1.3km Momaia tunnel, which will be the first twin tunnel ever built on a Romanian motorway.
The two tunnel tubes will traverse the Momaia mountain and be connected to each other by three cross-passages.
Following the cost increase, the total investment value of the project stands at 鈧�400 million.
The decision to increase the cost of the project, being undertaken by Austrian contractor Porr, is reportedly due to escalating construction-related expenses.
Challenging terrain
Project manager Norbert Horelein said, 鈥淚t is a state-of-the-art technology for tunnel construction and monitoring worldwide,鈥� adding, 鈥淭he ground is soft, it鈥檚 like digging in the sand.鈥�
The contract between CNAIR and Porr was signed towards the end of 2021, with construction starting this spring.
The contract covers a 60-month project, combining a 16-month design phase and a 44-month construction phase. The project is slated for completion at the end of 2026.
Porr has recruited a workforce of 300 labourers and a fleet of 100 machines for the project, as well as assembling a team of 60 tunnelling experts from Austria, with the number expected to double as work on the tunnel progresses.
