Helix Bridge

A friend and I recently did a photo walk along Singapore’s Marina Bay.  Our main destination is the Helix Bridge, which was officially opened in 2010.

The bridge is a pedestrian bridge that links the Youth Olympic Park to the Marina Bay Sands.

The bridge is lit by successions of lights that showcase its double-helix structure. It has four (4) viewing platforms and provides awesome panorama of Marina Bay skyline. From the platforms, one can clearly see my favorite Singaporean icon, “the Merlion”.

While walking at the bridge, my friend noticed pairs of letters CG and AT which are lit up at night in red and green colors. Having a biology background, I quickly thought of  the nucleobases that provide the nucleotide structure necessary to form base pairs, the guanine and cytosine  (GC) and the adenine and thymine (AT).  GC and AT comprise the four bases of Deoxyribonucleic acid (DNA). GC containing triple bonds and AT containing double bonds which stabilizes the structure, hence, the bridge was previously called “The Double Helix Bridge.”
