The Bhumibol Bridge (Thai: สะพานภูมิพล, RTGS: Saphan Phumiphon), also known as the Industrial Ring Road Bridge (Thai: สะพานวงแหวนอุตสาหกรรม, RTGS: Saphan Wongwaen Utsahakam) 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.

According to tradition, all bridges over the Chao Phraya in Bangkok are named after a member of the royal family.
