Singapore River

The Singapore River is a river that flows parallel to Alexandra Road and feeds into the Marina Reservoir in the southern part of Singapore. The immediate upper watershed of the Singapore River is known as the Singapore River Planning Area, although the western part of the watershed is classified under the River Valley planning area.
Singapore River planning area sits within Singapore's Central Area of the Central Region, as defined by the Urban Redevelopment Authority. The planning area shares boundaries with the following – River Valley and Museum to the north, Tanglin and Bukit Merah to the west, Outram to the south, and the Downtown Core to the east. The planning area is split into the three wharfs or quays in the area, Robertson Quay being the largest and most upstream, followed by Clarke Quay and Boat Quay.
Since 2008, the Singapore River was turned into a fresh water river after the completion of the Marina Barrage at Marina South.
The Singapore River is approximately 3.2 kilometers long from its source at Kim Seng Bridge to where it empties into Marina Bay; the river extends more than two kilometers beyond its original source at Kim Seng Bridge as Alexandra Canal, as far as the junction of Commonwealth Avenue.
The mouth of the Singapore River was the old Port of Singapore, being naturally sheltered by the southern islands. Historically, the city of Singapore initially grew around the port so the river mouth became the centre of trade, commerce and finance.
Old maps of the river state that it actually originates from Bukit Larangan (currently Fort Canning Hill).
From 1819, there was heavy traffic on the Singapore River due to rapid urbanization and expanding trade. At the same time, it brought in water pollution caused by the disposal of garbage, sewage and other by-products of industries located along the river's banks. The sources of water pollution in the Singapore River and Kallang Basin included waste from pig and duck farms, unsewered premises, street hawkers and vegetable whole sellers. Riverine activities such as transport, boat building and repairs were also found along the Singapore River.
Some 750 lighters plied along the Singapore River and Kallang Basin in 1977. Waste, oil spills and wastewater from these boats and lighters added to the pollution of the rivers. In 1977, Prime Minister Lee called for a clean-up of Singapore's rivers, which included the Singapore River and the Kallang River. The clean-up cost the government $300 million at the time and involved the relocation of about 4,000 squatters, along with hawkers and vegetable sellers, whose daily waste flowed into the river. Public housing was found for the squatters, while street hawkers were persuaded to move to established hawker centres. The government then completely dredged foul-smelling mud from the banks and the bottom of the river, clearing the debris and other rubbish.
Due to such cleaning efforts, the Singapore River has significantly changed from one that was heavily busy and polluted to one that is clean for marine animals. The re-emergence of monitor lizards and otters in the Singapore River has been attributed to the success of the river's cleanup.
Whereas the original mouth of the Singapore River emptied into Singapore Straits and its southern islands before major land reclamation took place, the Singapore River now empties into Marina Bay – an area of water partially enclosed by the reclamation work.
The Port of Singapore is now located to the west of the island, using most of the south-west coast, and passenger ships to Singapore now typically berth at the Singapore Cruise Centre at Harbourfront. Thus the Singapore River's economic role has shifted away from one that of trade, towards more a role accommodated for tourism and aesthetics for the commercial zone which encloses it. Traversing across the river is available via water taxis.
The river is now part of the Marina Reservoir after damming the Singapore River at its outlet to the sea to create a new reservoir of freshwater. The dam is known as the Marina Barrage.
There are a number of sculptures along the Singapore River. Many of these depict the life of people living and working along the river during the early days of Singapore.
Notable sculptures include:
Between 1819, when the first wooden jetty and the first bridge were built over the Singapore River in Singapore, and in 2015, 14 bridges were built across the river (or 17, although the Marina Reservoir, where the estuary is now located, is considered a Singapore River). Until 1819, the river could only be crossed by boats and ferries. Some of the bridges were demolished and rebuilt or their purpose was changed.
The first bridge in Singapore was built over the Singapore river in 1819 where the Elgin Bridge now stands. There have been two Elgin bridges at some point. The first iron-made Elgin Bridge was built in 1862 and named after Lord Elgin. It was later demolished and replaced with the current Elgin bridge in 1926. Other bridges along the river include the Coleman Bridge (1840), Kim Seng Bridge (1862), Cavenagh Bridge (1869), and Read Bridge (1889). The most recent bridges are the Helix Bridge (2010), Bayfront Bridge (2010), and the Jubilee Bridge (2015).
