Vietnam is changing rapidly as it modernizes, with roads being upgraded on a regular basis and cities changing road patterns to accommodate the needs of growing populations. In our most recent visit, to Hanoi, the airport had a new terminal, there was a new bridge over the Hong Song (Red River), and a new motorway into the city was open. Scale 1:920.000.
