Combined (rail and motor) road from Adler to the mountain resort Alpika-Service nearly 48.2 km long will be not only the main passenger artery of 2014 Olympic Games, but will also improve regional infrastructure due to connection to M-27 federal road through traffic interchanges. The new Adler – Krasnaya Polyana road is laid mainly on the left bank of Mzymta River. Designers considered all features of natural landscape and traced railway and traffic in parallel to each other. Twelve tunnels with the total length of 27 km and 45 bridges will be built here. This solution allows nearly streamlined connection between Adler and Alpica-Service terminal station.
