The viaduct connects the Tsing Ma Bridge and Kap Shui Mun Bridge with an exit to Ma Wan Road, and is part of the Lantau Link (formerly known as the Lantau Fixed Crossing) and Route 8.

[3] The Ma Wan Viaduct has the same cross section as the Tsing Ma and Kap Shui Mun Bridges: a dual three-lane carriageway on the upper deck and two tracks of railway and two lanes of roadway in the enclosed lower deck.

The lanes on the lower deck allow for maintenance and the diversion of traffic during high winds.

The railway carries the Tung Chung and Airport Express lines of Hong Kong's Mass Transit Railway (MTR).
