CIVIL & STRUCTURAL ENGINEERING
The Adventure Bridge
This bridge also adopted a curved alignment, with a 14.2 m
radius, to over-cross the waterway. This ‘horse-shoe’ shaped
footbridge is supported by slanting columns to create another
aesthetically unique bridge. The creation of the curved bridge
beams with slanting bridge columns entailed painstakingly
thorough computer modelling and design, which are not
required for normal straight bridges.
The footbridge is designed to cater not only for pedestrian
traffic but also for the imposed and lateral impact loads from
maintenance vehicles that use it to cross the waterway.
The Adventure Bridge.
The eye-catching steel bridge was designed to resemble a
wooden suspension bridge that blends with the natural park
setting. The prominent landmark provides visitors with an
‘adventurous’ experience while crossing the waterway and
enjoying the scenery in the park. Approximately 46 m long
and 1.2 m wide, it utilises suspension wires together with
steel trusses.
The Wave Bridge
The shape of the bridge, which connects the banks of both
the promenades, represents a continuation of the undulating
landform. The wavy railing design further accentuates the
characteristics of the meandering and undulating landscape.
The Sunrise Bridge.
This slightly curved footbridge is 225 m long with widths varying
from 2.4 m to 4.1 m, and it spans 30.5 m across the waterway.
The Wave Bridge provides another pedestrian crossing at an
important location.

The Sunrise Bridge
The Sunrise Bridge is the highlight of the eastern end of the
waterway. The bridge offers the best view of the waterway and
Serangoon reservoir as it was designed to be slightly elevated,
to enable visitors obtain a good view of the sunrise. The bridge
design continues the language of the weaving boardwalk along
the river banks, blending the rustic flavour with a modern twist.
