It will run along the route: Buzău, Focșani, Bacău, Roman, Pașcani, and Suceava, connecting to Ukraine's M19 highway near Siret.

The Pașcani – Siret section will be financed through EU funds, while the government wants the Ploiești – Pașcani section (excluding the Bacău bypass) to be financed through the Romanian PNRR (short for Planul Național de Redresare și Reziliență, part of the Next Generation EU package).

On 30 May 2016, the construction works at Bacău bypass started,[13] and they were expected to be finished by 2022,[14] but the contract with the Turkish company Eko İnşaat ve Ticaret was terminated in April 2017, due to financial difficulties of the constructor.

[17] All other sections are in the feasibility study and technical project phase,[18] with the exception of the motorway segments between Ploiești and Focșani via Buzău.

The explosion was caused where the motorway's construction site crossed a gas pipeline, which was initially believed to be at a depth of 1,8 meters, but had turned out to be much more shallow.

Transgaz, the national gas distribution provider, blamed the construction company for performing unauthorized work in the area.
