Greek company Aktor started boring the tunnels from Ormeniș and Racoș on the middle lot Apața - Cața with tunnel boring machines. Tunnels in total are 12 kilometers long but because they are twin tubes, total 24 kilometers of tunnels need to be bored. 

The company Aktor is also working on another project the The Apața - Cată lot. But there Aktor's progress rate is only 20%.
