A bridge over the Mzymta River along the newly-built 48-kilometer combined high speed railway and road links the coastal and mountain clusters of venues for the 2014 Winter Olympic and Paralympic Games in Sochi, Russia. Experts believe the controversial road, which includes 12 tunnels and 46 bridges, has caused damage to the river and the fragile local ecosystem, which includes many rare plant and animal species.
