Romania's most complex highway segment, featuring giant viaducts, nears opening

A new, challenging segment of Romania's Transylvania Motorway (A3) is nearing completion, with approximately 12 kilometers between Zimbor and Poarta Sălajului slated to open to traffic this summer. The Ministry of Transport announced the upcoming opening, highlighting the significance of this section in the Sălaj county.

State Secretary at the Ministry of Transport, Horațiu Cosma, provided an update on the A3 motorway construction in Sălaj county, indicating that traffic on the Zimbor-Poarta Sălajului stretch is expected to commence in July. Despite its relatively short length, this segment is considered one of the most difficult sections constructed on the motorway to date, presenting significant engineering challenges.

Cosma described the segment as traversing hilly terrain and requiring highly complex infrastructure. This includes over 3 kilometers of viaducts, some reaching heights of up to 50 meters, more than 5 million cubic meters of excavation, approximately 4 kilometers of retaining walls, and extensive work on slope stabilization with anchors and drainage systems.

Currently, the Romanian construction company is finalizing work at the Românași interchange and addressing a recent landslide on a highway cut. Concurrently, CESTRIN specialists are conducting necessary tests for the reception of works and the subsequent opening of the road.

Progress is also being made on the subsequent section between Zimbor and Nădășelu, where viaducts are under construction, embankments are being filled, landslides are being remediated, and asphalt is being laid, along with the installation of safety barriers and road markings. The main works on this part are expected to be completed by the Romanian contractor in August, while the Turkish contractor aims to finish the viaducts by year-end.

Looking ahead, 2026 is projected to be a pivotal year for the Transylvania Motorway, with an estimated 100 kilometers of motorway opening in Sălaj, Cluj, and Bihor counties. The most complex part of the motorway, involving the Meseș Tunnel, Romania's longest road tunnel, is still to be completed in the coming years.
