Bridges and Cables
Another obstacle for navigation can comes from the bridge air clearance and the navigation quadrangle. The bridge air clearance is defined as being the vertical height of the quadrangle (defining the width of the navigation channel) that can be drawn under the bridge without touching the bridge beams.
The following table gives the navigation quadrangles of the bridges over the Mekong mainstream between the Green Triangle and the sea.
