Sochi’s road transport network will be significantly improved in time for the Games. One major project is the construction of a combined road between Adler and “Alpika Service.” A single railway track with two-way inserts will be laid along the left bank of the Mzymta River to provide simultaneous movement of trains in both directions. In addition, a two-lane road will be laid parallel to the railway track. These projects will shorten the trip between the coastal and mountain clusters to about 30 minutes.
In order to reduce road congestion, a flyover with three overpasses will be designed to replace the existing Adler ring, a strategically important transport hub.
Sochi will also build a bypass to decongest the city's streets. The road will include 15 bridges and five tunnels with a combined length of more than 10 km. New road systems will connect sporting and tourist venues to make travel convenient for both participants and guests of the Games. These will include two highways which will lead directly to the Olympic venues in the mountain cluster, with a capacity for 14,000 cars per day.
Special Olympic lanes will be designated during the Games for moving guests and participants.
Safety is a primary concern in the construction of the mountain roads. Protective barriers are being put in place against potential avalanches and mudslides.
