The Somdet Phra Pinklao Bridge (Thai: สะพานสมเด็จพระปิ่นเกล้า, RTGS: Saphan Somdet Phra Pinklao, pronounced [sā.pʰāːn sǒm.dèt pʰráʔ pìn.klâːw]) is a bridge near the Grand Palace over the Chao Phraya River in Bangkok, Thailand.
It was opened to traffic on 24 September 1973 by Prime Minister Thanom Kittikachorn.
The bridge was built by the joint company Obayashi Gumi Ltd. and Sumitomo Construction Co. Ltd under the supervision of Swiss Engineering Project (SEP) which acted as trustee for the Department of Public and Municipal Works (DPMW).
[3] It is feared that the heavy traffic crossing Pinklao Bridge could cause structural damage to the old buildings on Ratchadamnoen Avenue.
[5] Some residents expressed their desire in 2010 to have the bridge dismantled mainly due to the air and noise pollution it brings to the old district of Bangkok.
