Sakhalin Tunnel

The Sakhalin Tunnel (Template:Lang-ru) is an incomplete and currently postponed construction project, which after completion would connect the island of Sakhalin with mainland Russia via a tunnel of approximately 10km under the Strait of Tartary.

History

Early proposals and planning

The concept of a tunnel under the Strait of Tartary has existed since the 19th century, although it was never seriously pursued due to economic reasons. Studies into the feasibility of the project were first undertaken by the Soviet Union in the late 1930s, although the Second World War made progress at this time impossible. Stalin later announced in 1950 his intension to build a railway link to Sakhalin, either via rail ferry, a bridge or a tunnel. The decision to being constructing a tunnel was announced by the Soviet government on May 5, 1950, along with a rail ferry link to serve as a temporary solution. The project was intended primarily to serve a military purpose, allowing better connection between Sakhalin and the mainland for sections of the Red Army stationed on the island.

Construction

The construction of the railway connection from Selekhino near Komsomolsk-on-Amur to the intended tunnel portal was assigned to the Soviet Ministry of Internal Affairs, with the Ministry of Transport in charge of the tunnel itself. In 1952 the project was transferred to the full management of the Ministry of Internal Affairs.

The planned route on Sakhalin was intended to run 327km from Cape Pogibi, where the tunnel should resurface, to Pobedino, 10 km north of Smirnykh and the then northern terminus of the railway in Sakhalin. The length of the tunnel between Cape Pogibi and Cape Lasarev was planned to be around 10 km. On the mainland, a rail line was to be constructed to the railway connecting Komsomolsk-on-Amur with Sovetskaya Gavan, now a section of the Baikal Amur Mainline.

The project was planned for completion by the end of 1953, and to be in full operation by the end of 1955. Goods traffic on the line was projected to reach 4 million tonnes per annum.

The construction was largely undertaken by gulag prisoners, with the main camps situated at Tymovskoye on Sakhalin and at De-Kastri on the mainland. At the start of 1953, more than 27,000 prisoners were working on the project. Particularly on the island, conditions for the forced laborers were worsened by a lack of any real infrastructure or the required technology. Due to the tight time schedule, conditions in the camps were very poor, well below the official state regulations for prison camps.

After the death of Stalin, work on the project stopped, with the tunnel allegedly almost halfway across the straits. While the reasons for cancellation of the project are not fully clear, some sources have indicated that because of numerous amnesties granted to prisoners after Stalin's death, there was no longer the required workforce.

Completed sections of the project

Around 120 km of track along the right bank of the Amur River from Selekhino to Chorny Mys was completed. This was later used for transport of lumber by the Soviet forestry industry, but was later closed and the track has been largely dismantled.

Remains of the tunnel entrance are still visible around Cape Lasarev. No new track was built on Sakhalin, although preparatory earthworks on the planned route was used in the construction of a road from Nysh to Pogibi.

Current operations and future prospects

Since 1973, a train ferry has connected Vanino (on the mainland near Sovetskaya Gavan) with the town of Kholmsk on Sakhalin.

Even after the collapse of the Soviet Union, there have been calls for a revival of the project from politicians, although there have been concerns that the costs of the project would outweigh the benefits. However, there have been recent signs that the link is under serious consideration, including an announcement of support from Russian President Dimitry Medvedev im November 2008. The project is proposed to be completed by 2030.

New plans would see the connection in Sakhalin at Nogliki, which has in the meantime been connected to the island's rail network. Works to convert the island's narrow-gauge rail system, a legacy of the previous Japanese colonisation of the southern half of the island, to the broader Russian standard gauge.

There have also been proposals to connect the southern tip of Sakhalin to the Japanese island of Hokkaido via a 40km long bridge or tunnel, thereby allowing a direct land transport link for container traffic from Japan to the Asian mainland and Europe.
