A3 Bucharest–Brașov Motorway
Motorway linking Bucharest to Brașov via Ploiești and the Prahova Valley, part of the planned Bucharest–Borș (Hungarian border) route. The Bucharest–Ploiești section (62 km) opened in July 2012. The Ploiești–Comarnic section (48.6 km) is still in pre-feasibility, while the difficult Comarnic–Brașov mountain section (58 km) has seen its concession and PPP tenders repeatedly cancelled; only the Râșnov–Cristian segment (6.3 km) is in service.
