HULHULE-MALE’ BRIDGE PROJECT

EIA for the proposed Hulhule-Male’ Bridge Project
with the Hulhule-Hulhumale’ link road via the southern tip of Hulhule Island. Thus, the best
landing points in terms of allowing traffic flow are the two proposed points. This site has also
been finalised with extensive consultations with the Government agencies.
In addition the proposed location offers better terrain to construct the bridge approach due to the
presence of gentle reef slope. This is crucial as the bridge approach can take up considerable
space on land as it has to be elevated. There is very limited space to spare in Male’ Island proper
for the approach bridge.
The location also offers the least impact location for traffic assimilation in terms of disturbance
to the local buildings and houses in the vicinity.
2.3.4.2 Justification for the location, depth and size of piers
The main factors influencing the bridge design at the proposed location include submarine
topography, aviation height limits, navigation clearance requirements and the deep water sea bed
conditions. Based on these limitations and the principle of simple design used for the project,
pre-stressed concrete V-shaped outrigger six-span continuous steel structure scheme is selected
for main bridge.

The design is controlled by factors such as aviation height limit on airport side, elevation at
breakwater on Male’ side, design water level, wave height, location of intersection, water depth
and scouring depth as well as the practicality during construction and aesthetic factors.
The bridge pier location is determined in accordance with bridge type and spanning length
scheme for main bridge and approach bridge. The foundation form and pile foundation depth are
determined based on the geological investigation results, calculation results of structural bearing
capacity and the bridge pier dimension.
