The £5.9bn rail tunnel would link Russia and the US (Image: Anadolu via Getty Images) Moscow has put forward a plan for a "Putin-Trump" rail tunnel built by Elon Musk - which would link Russia and the US in a symbol of "unity". ‌ The 70-mile tunnel would be built under the Bering Strait and unlock joint exploration of natural resources, a Kremlin envoy has suggested. Kirill Dmitriev - Putin's investment envoy and CEO of Russia's RDIF sovereign wealth fund - said the project would be funded by Moscow and "international partners", costing $8bn (£5.9bn). The proposal suggests using The Boring Company, a US tunnel construction company owned by Elon Musk, to built the bridge in under eight years. ‌ Kirill Dmitriev, Putin's investment envoy, proposed the $8bn idea (Image: Getty Images) The Bering Strait is 51mi (82km) wide at its narrowest point and separates Russia's Chukotka region from Alaska. There have been talks to connect the two points for at least 150 years, with a number of projects proposed but never implemented. Dmitriev wrote to Musk on X: "Imagine connecting the US and Russia, the Americas and the Afro-Eurasia with the Putin-Trump Tunnel - a 70-mile link symbolizing unity." He added that a similar idea - the construction of a 'Kennedy-Khrushchev World Peace Bridge' - was proposed during the Cold War and shared a sketch highlighting the route it may have taken between Chukotka and Alaska.

The time has come to do more and connect the Continents for the first time in human history. The time has come to connect Russia and the US," Dmitriev said. Musk has not yet commented on the proposal. Follow Daily Mirror:
