The Bhumibol Bridge also known as the Industrial Ring Road Bridge is part of the 13 km long Industrial Ring Road connecting southern Bangkok with Samut Prakan Province. The bridge crosses the Chao Phraya River twice, with two striking cable-stayed spans of lengths of 702 m and 582 m supported by two diamond-shaped pylons 173 m and 164 m high. Where the two spans meet, another road rises to join them at a free-flowing interchange suspended 50 metres above the ground. Walk around a bit near the canal, the park and the roads under the bridge to find some interesting shots. Only problem with this location, is that you can only go by taxi, and it's quite far from the city centre. You will also need a bit of luck to find a taxi on your way back.
