A US official familiar with the negotiations confirmed the temporary route was discussed and said it would be limited to a period of 60 days, ABC reports

During the 60 days, negotiators would work on a long-term deal to fully open the strait and continue hashing out a nuclear deal. This arrangement would seemingly formalize Iranian control of the waterway.   The official cautioned that nothing is final until it is publicly announced.   Omani officials have proposed a Gulf-backed plan allowing Iran to receive voluntary contributions modeled after Asia's Strait of Malacca, to cover costs for security and environmental protection.  A source familiar with the proposal said voluntary payments could be on the table in the interim agreement. Another U.S. official said the Trump administration wants total freedom of commercial navigation through the waterway without Iranian tolls or any arrangement requiring ships to obtain Tehran’s approval before transiting the strait.
