Bhumibol Bridge

Bhumibol Bridge (Thai: สะพานภูมิพล) is located on the chao phtaya river in Samut Prakan Province, Thailand. It connects Samut Prakan Province with Bangkok in the south. The chao phtaya river has a big C-shaped bend here, so the Bhumibol Bridge has crossed the chao phtaya river twice, and there are 2 navigation bridges in the north and south.

The Bhumibol Bridge has a total length of 8.1 mi (13 km) and was opened to traffic on September 20, 2006 before it was officially opened on December 5, 2006. It is part of Bangkok Industrial Loop. It cost 8.739 billion baht ($290 million).

There is an artificial canal near this bridge called Lat Pho Canal, which is about 1968 ft (600 m) long. It also runs through the C-shaped bend of the chao phtaya river and is juxtaposed with the overpass of the Bhumibol Bridge.

Lat Pho Canal and Bhumibol Bridge are different sub-projects of the same big project.

History

Birth background

• On November 7, 1995, due to the impact of flooding, King Bhumibol Adulyadej of Thailand decided to build a better road network to support the development of the industrial area near Samut Prakan and the port of Bangkok.
• On March 5, 1996, the Thai government passed a resolution calling for the construction of the Industrial Ring Road, which connects the industrial zone with the Port of Korontoy. It is approximately 15.5 mi (25 km) in length and 7 lanes wide for heavy trucks.

Construction process

• On May 29, 2000, King Bhumibol Adulyadej of Thailand presided over the foundation laying ceremony of Industrial Ring Road. This project is a Royal Thai Project.
• In 2003, the Royal Thai Irrigation Bureau launched the Lat Pho Canal improvement project initiated by the Royal Government.
• On September 20, 2006, the Industrial Ring Road Bridge was opened to traffic.

• On December 5, 2006, the Industrial Ring Road Bridge held a formal opening ceremony.
• On October 21, 2009, King Bhumibol Adulyadej of Thailand named the bridge “Bhumibol Bridge”.
• On November 24, 2010, King Bhumibol Adulyadej of Thailand held the opening ceremony of Bhumibol Bridge and Khlong Lat Pho Floodgate.

Building technical parameters

The Bhumibol Bridge has a total length of 8.1 mi (13 km), including 2 main bridges, 1 overpass and approach bridges. The bridge was designed by Swedish engineer Paulle Gustafsons.

2 main bridges

Bhumibol Bridge 1

Bhumibol Bridge 1 is the North Bridge. This is a 2303 ft (702 m) long cable-stayed bridge with a longest span of 1070 ft (326 m), 7 lanes and 2 high pillars, and a tower height of 568 ft (173 m). Deck height is 164 ft (50 m).

Bhumibol Bridge 2

Bhumibol Bridge 2 is the south bridge with a total length of 1909 ft (582 m) and a longest span of 1306 ft (398 m). The structure is almost the same as Bhumibol Bridge 1, with 7 lanes and 2 high columns, the tower height is 538 ft (164 m), and the clearance height under the bridge is 164 ft (50 m).

Khlong Lat Pho Floodgate

In order to shorten the distance of the river and speed up the flow to the river. The original 1968 ft (600 m) length of Lat Pho Canal was expanded. The depth was increased from 7 ft (2 m) to 23 ft (7 m), and the width was expanded from 49 ft (15 m) to 213 ft (65 m). Relieve the flooding in Bangkok area.

Four sluices 46 ft (14 m) wide and 31 ft (9.6 m) high were installed. They are called Khlong Lat Pho Floodgate.

From November 1, 2018, for safety reasons, motorbikes will be banned from the Bhumibol Bridge.
