The A150 autoroute is a short motorway northwest of Rouen, France.

Opened in 1973, the motorway started in Rouen at the entrance to Déville-lès-Rouen where it has been connected to the Gustave-Flaubert bridge since 2008 (allows the A150 to be connected to the A13 via the so-called Sud III collector and the A139).

It heads northwest, with the A151 branching off towards Dieppe, it continued to Barentin (where it served the Mesnil-Roux shopping centre).

The section was inaugurated on 29 January 2015, 4 weeks ahead of schedule but its opening,[1] originally scheduled for Monday 2 February, was postponed to 9 February in order to finalize some security elements.

Financing at around 240 million euros, its design, construction and operation have been granted to the Albea consortium (Autoroute Liaison Barentin Écalles-Alix)[2] for a period of 55 years, with NGE having been the lead manager and includes Fayat, OFI Infravia and Société Financière A150.
