Morocco's National Highways Company (ADM) has announced the opening of the new Tit Mellil–Berrechid motorway (A31) on Thursday, November 27. Built at a cost of 2.5 billion dirhams, this 30-km highway represents a major addition to the national network, delivered several months ahead of schedule and designed entirely by 100% Moroccan expertise, reads a press release. The A31 directly links the Casablanca bypass (A1) at Tit Mellil to the Casablanca–Marrakech motorway (A3) and the Berrechid–Beni Mellal motorway (A4). With an initial traffic forecast of 20,000 vehicles per day, it is expected to significantly ease congestion across Greater Casablanca, shorten travel times for users coming from the north and east toward the south and center, and offer an alternative route to Mohammed V International Airport, helping relieve pressure on the heavily used Casablanca–Airport section, which now exceeds 75,000 vehicles daily. The project includes two interchanges (on RR315 and RN9), four viaducts over Oued Zririf, El Fayda, and El Himer, and 24 restoration structures to maintain local road continuity. It is the first motorway in Morocco initially designed in a 2x3-lane configuration, and features new-generation safety barriers deployed for the first time in the country. ADM notes that all stages, from technical design to construction, were carried out by Moroccan teams, leveraging more than 35 years of expertise in major infrastructure projects. The company highlights that the new highway strengthens Morocco's mobility network as the country prepares to host major international events, in line with the strategic vision of King Mohammed VI.
