The A4 motorway (Romanian: Autostrada A4) is a motorway in Romania that serves as a bypass for the city of Constanța, between Ovidiu and the Port of Constanţa, connecting with the A2 motorway via an interchange southwest of the city. It is 22 km long and is planned to be extended to approximately 60 kilometers, stretching further south to the Bulgarian border south of Mangalia, along the western Black Sea coast. The motorway is part of an extension of the Pan-European Corridor IV, that will be connecting with the Bulgarian city of Varna.

The contract for the construction of the stretch of motorway between Ovidiu and Lazu was awarded in September 2008 to the joint venture between the Italian company Astaldi and the Spanish company FCC Construction, and was due to be completed until November 2011.

A new bridge is under construction over the Danube – Black Sea Canal, downstream of the Agigea lock, in order to allow access to the busier southern terminal of the Port of Constanţa directly from the motorway. Works began in July 2010, and are planned to be completed in 2014.

The bypass was initially built with funds from the state budget, but in the end of 2014, the European Commission awarded funds for the construction from the Cohesion Fund.
