Burma: Where India and China Meet 507 Frank Outrain Mules Cross a Stream by Cable Bridge On the Yunnan side of the Shweli River, in territory that is impassable for wheeled vehicles, lies this section of the old China-Burma caravan trail.

This span, laid on strong cables, is one of the better examples of the old type.
