Bridges
Bridges are essential elements to many transportation systems, including rail, highway and road systems. Design schemes vary depending on various conditions such as terrain, geology, natural hazards and physical requirements (loading, span and clearance). In the past years, MAA has been devoted in bringing new technology into bridge design. Examples include the first usage of incremental launching method for Touchien Bridge, the second hybrid arch/cable type steel bridge, Nanfang Au Bridge, in the world, the first cable stayed bridge n Costa Rica, etc. Other than design, MAA also provided construction supervision and rehabilitation, inspection and repair services.

Viaducts
As cities develop, land space become limited for new construction and/or widening of existing roads and highways to meet increased demands of traffic flow. As a result, many cities adopt viaducts and elevated structures.
