The Sheares bridge curves over Marina Bay - there are two portions, the first parallel to the Helix pedestrian bridge (overlooking Marina Bay Sands) and the second, crossing over Gardens by the Bay. The bridge used to be part of the East Coast Parkway highway, but the highway is now diverted and the bridge is part of Sheares Avenue now. It's a little bit of a scramble up to the bridge (you can access it either from the city side, or from Gardens by the Bay East), but once up there, spectacular views over Marina Bay. Approaching from Tanjung Rhu side, you get different views. Once on the bridge, you can't cross over the lanes of traffic (obviously!), so decide which side you want oogle before climbing. For walking directions, go to Wikiloc and google "mostlyharmless" for trail maps. Don't go when the sun is up: there is no shade, tons of concrete and you will likely vanish in a puff of superheated steam.
