Morocco has renamed its 1,055-kilometer Tiznit-Dakhla expressway the "Donald J. Trump Highway," a decision confirmed by King Mohammed VI in a letter to the US president dated 2 July and published over the weekend by Morocco's state press agency. Morocco described the renaming as a mark of "deep appreciation" for Trump. The highway runs through Western Sahara, one of the world's most disputed territories BBC Bloomberg.

The road connects Tiznit in southern Morocco to Dakhla, a city in Western Sahara. Most of Western Sahara is controlled and claimed by Morocco, while a portion is held by the Polisario Front, a Sahrawi national liberation movement that has sought independence for the territory since the 1970s. King Mohammed VI called the road a "strategic axis" linking the north and south of the kingdom BBC Al Jazeera.

Trump amplified the announcement with a post on Truth Social that included a video stating the highway cost nearly $1 billion (£740 million) to build BBC.

The renaming ties directly to a single diplomatic decision made during the first Trump administration. In December 2020, the United States recognised Morocco's sovereignty over Western Sahara as part of a deal in which Morocco agreed to normalise relations with Israel. That recognition broke with decades of international consensus: the UN had treated Western Sahara as a non-self-governing territory — meaning a territory that has not yet achieved full self-government and whose people are entitled to a referendum on self-determination. No previous US administration had formally endorsed Morocco's claim, and the move reshaped the diplomatic landscape for the conflict BBC.

For Morocco, the highway renaming serves as a lasting expression of gratitude for that recognition. Putting Trump's name on infrastructure spanning Western Sahara is itself a political signal: every traveler, map, and trade route that references the "Donald J. Trump Highway" reinforces the Moroccan state's position that the territory is integrated, developed, and sovereign. The road's physical path from Tiznit southward through Dakhla embeds that claim in asphalt and signage.

The broader context here is the ongoing competition between Morocco's consolidation strategy and the Polisario Front's claim to the territory, adjudicated through a stalled UN peace process. Morocco has pursued what it calls its "Autonomy Plan" for Western Sahara, proposing limited self-governance under Moroccan sovereignty, while the Polisario Front and its principal international backer, Algeria, continue to press for a referendum on full independence. The Trump administration's 2020 recognition tilted the diplomatic balance toward Rabat, and the renaming of a major infrastructure asset in Trump's honor signals that Morocco views that tilt as worth cementing.

The road itself carries economic and strategic weight. Running 1,055 kilometers (655 miles), the expressway connects Morocco's population centers to the resource-rich southern provinces and toward West African trade corridors. Dakhla, the southern terminus, sits near rich fishing waters and has become a focal point for Moroccan development spending in the territory. The nearly $1 billion construction cost reflects the scale of Rabat's infrastructure commitment to the region BBC.

For the Polisario Front and its supporters, the naming of a highway through Western Sahara after the US president who unilaterally recognised Moroccan sovereignty will be read as a provocation, however ceremonial. It is a reminder that the 2020 recognition has not been reversed, and that Morocco continues to treat the territory's infrastructure as its own.

The letter from King Mohammed VI, dated 2 July and surfaced through official channels in early August, was timed and delivered as a bilateral gesture to Washington. Whether it signals further US-Moroccan coordination on Western Sahara policy during a second Trump term is an open question. What is certain is that Morocco has now placed the name of the 47th president on a road through a territory whose status the international community has not settled and that Rabat has no intention of relinquishing BBC.
