Lefortovo Tunnel: high accident rate caused by skidding on ice
Located in Lefortovo, a suburb of the Russian capital, the largest city entirely on the European continent, the Lefortovo Tunnel, part of the Third Ring Road, was nicknamed The Tunnel of Death, owing to its high accident rate, many caused by skidding on ice in winter.
It is the fifth longest in-city tunnel of Europe. The tunnel is asphalted and opened in 2003. It’s 3.2 km (2.0 mi) long with 7 lanes (3 lanes northbound and 4 lanes southbound). The tunnel runs under the Yauza River, and water leaks in at some points, causing the water on the road's surface to freeze.
