Phra Pin-klao Bridge
The Somdet Phra Pinklao Bridge is a bridge near the Grand Palace over the Chao Phraya River in Bangkok, Thailand. It links Rattanakosin Island with Thonburi.
Background
The bridge is named after Pinklao, vice-king of Siam, 1851–1866. During its construction, the bridge was referred to as the Tha Chang Wang Na Bridge. In June 1973, it was renamed the Somdej Phra Pinklao Bridge in honour of Prince Pinklao.The Chalerm Sawan 58 Bridge along two pedestrian bridges crossing the northern part of Khlong Khu Mueang Doem had to be dismantled to make way for the new bridge and its access road.
Construction of the bridge started on 4 August 1971. It was opened to traffic on 24 September 1973 by Prime Minister Thanom Kittikachorn. The bridge was built jointly by Obayashi Gumi Ltd. and Sumitomo Construction Co. Ltd under the supervision of Swiss Engineering Project which acted as trustee for the .
The main drivers behind the construction of the bridge were:
- To alleviate the traffic congestion over and around the Memorial Bridge and to shorten travel time and cut costs
- To foster inter-city relations between Bangkok and Thonburi
- To facilitate the development in the vicinity of the bridge
It is feared that the heavy traffic crossing Pinklao Bridge could cause structural damage to the old buildings on Ratchadamnoen Avenue. 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. The Cheonggyecheon project in Seoul is given as an example of the positive effects the dismantlement could have.
