Previously, Ștefan-Ovidiu Popa announced that the opening of the Tigveni–Curtea de Argeș section to traffic had been postponed because the Momaia tunnel could not be put into operation without specialized teams for monitoring, maintenance, and emergency interventions. The minister said at the time that discussions had begun with CNAIR Director General Cristian Pistol to organize competitions and hire staff in stages, while the duration of the delay could not be estimated.
Work on the 9.86 kilometers of the section is reported to be 99% complete, and the contractual deadline is February 2027. The tunnel is 1,350 meters long and has more than 2,500 monitoring points (cameras and sensors), while the maximum speed inside is 80 km/h; safety tests and system adjustments were to be completed before it was opened to traffic.
