Why is Iran redirecting ships even after reopening the Strait of Hormuz? Tehran has flagged risks of sea mines and redrawn routes, pushing vessels into tightly controlled corridors under its watch. All you need to know about the alternative routes shared by the IRGC.
Iran on Thursday (Apr 9) announced alternative routes for ships travelling through the Strait of Hormuz. Flagging the risk of sea mines in the main zone of the vital waterway, Iran's Revolutionary Guards, in a statement, advised ships to "comply with the principles of maritime safety" and opt for alternative routes. This comes a day after a two-week ceasefire was announced between the United States and Iran. The fragile includes the reopening of the Strait of Hormuz, Iranian Foreign Minister Seyed Abbas Araghchi announced in a post on X on Wednesday (Apr 8). The closure of the chokepoint since the Iran war began on February 28 has sent oil prices surging past $100 a barrel, and even pushed several Asian nations toward fuel rationing.

According to the statement published in local media, the Iran Ports and Maritime Organization has redrawn the traffic separation in the Strait to "avoid possible collisions with naval mines." Notably, reports suggest that Iran has laid up to a dozen mines in the waterway this month. However, the claims remain unverified.
According to Maritime Executive, the new scheme by the Iranian maritime authority appears to be designed to steer inbound traffic between the islands of Qeshm and Larak, along the so‑called "Tehran toll booth" corridor controlled by the IRGC. Meanwhile, the outbound traffic lane now runs just south of Larak, remaining within Iranian territorial waters and keeping vessels within easy range of IRGC escorts, boardings, and identity verification checks.

The chart also introduces a designated "danger zone" marked as "transit prohibited" in the area that previously supported deep‑sea navigation. The coordinates of this zone encompass the IMO‑approved traffic separation scheme (TSS) located off the northern tip of the Musandam Peninsula.
In addition, the warning area appears to extend over the newly established, Omani‑administered shipping lane at the far southern edge of the strait, seemingly contradicting the widely discussed Omani‑Iranian agreement governing transits through Oman’s territorial waters.
