AH1 is QL1A on some maps. To go to the north, like Nha Trang, Da Nang or Ha Noi, you could try going to junction of QL1A and DT43. It's a highway, where lots of cars,
busses and some tracks are passing by. And this place is easily reached by bus from the city centre, check out google maps directions for public transport.
=== Towards [[Cambodia]] ===
Take a bus to ''
Ben Xe An Suong''. This is a huge bus station, so there are about 15 lines from somewhere in the centre going there. Walk out of the bus station and you'll be standing right on the motorway that leads straight to the border.
