MOSCOW/WASHINGTON (Reuters) - Companies building a multi-billion dollar bridge to link the Russian mainland with annexed Crimea, a project close to the heart President Vladimir Putin, were targeted by the United States in an updated sanctions blacklist on Thursday.

The U.S. Department of the Treasury added dozens of people and companies to the list, first introduced after Russia annexed the Crimean peninsula from Ukraine in 2014 and expanded over its support for separatist rebels in the east of the country.
