Autostrada A1 București–Nădlac

Romania's first motorway, built 1967–1972 and financed from the state budget; fully rehabilitated later (a 1997 FAT consortium contract for €27M over 22 months)

Prima etapă, circa 15 km de la Bascov (Pitești) la nodul rutier Merișani, a fost deschisă în decembrie 2024, cu opt luni înainte de termenul contractual. Restul de circa 15 km până la Curtea de Argeș a fost deschis în iunie 2025.

Include tunelul Momaia (circa 1,35 km), primul tunel de autostradă forat din România. Lucrările erau la 99% în septembrie 2026, iar deschiderea depinde de testele de siguranță ale tunelului cu ISU, programate la sfârșitul lui septembrie. CNAIR estimează deschiderea circulației până la sfârșitul lui 2026; termenul contractual este februarie 2027. HotNews indică martie 2022 pentru începerea contractului (întâi proiectarea) și toamna lui 2023 pentru începerea lucrărilor.

Lots 2 and 3 (Tigveni – Boița), the Carpathian crossing, under separate execution contracts: lot 2 Mapa–Cengiz (Boița – Cornetu, 31.33 km), lot 3 Webuild (Cornetu – Tigveni, 37.4 km). Staged completion per OpenStreetMap construction tagging: lot 3 (Tunel Poiana, Polanta) 2028, lot 2 Boița–Cornet (Tunel Lazaret 1/2, Robești, Câineni, Boița 1/2, Balota) 2031, so the full stretch is in service only from 2031. Section 4, Tigveni – Curtea de Argeș, is recorded as its own lot.

The part of Lugoj–Deva lot 2 opened on 6 March 2017, bypassing Făget as far as Margina. The rest of the lot, east of Margina, was re-contracted in 2022 and is recorded separately as Margina – Holdea

The last gap in the A1 between Boița and Nădlac. The contract covers just over 13 km: the 4.03 km of Section D left unfinished east of Margina and the 9.13 km of Section E with the twin-bore bear tunnels, 2.13 km in total (DRDP Timișoara figures, January 2023). CNAIR and most reports quote only the 9.13 km. The start order for design was issued on 5 December 2022; tunnel excavation began at the start of 2025 and both bores of Tunnel 2 (1,985 m and 1,825 m) were through by 18 September 2026, with physical progress past 75%. CNAIR's director general expects traffic in the first half of 2027
