Planning

The Circle Line was first known as the Marina Line in May 1998. The Marina Line was initially planned as a 12-station underground line, starting from Template:STN and Template:STN via the Template:STN to either Template:STN or Template:STN station. However, the Chinatown leg was later truncated and was reduced to 6 stations up to Template:STN station. On the other hand, a further extension towards Upper Paya Lebar was added in the year 2000. The Marina Line was also merged with a MRT Line that goes from Paya Lebar to Buona Vista via Serangoon and Bishan to form Circle Line Stage 3 and 4 in 2001. Stations in Circle Line that were a part of the original Marina Line plans include Template:STN, Template:STN, Template:STN, Template:STN, Template:STN and Template:STN. Also, the part of the Marina Line from Template:STN to Template:STN is now part of the Downtown Line. Circle Line Stage 5 was again finalised in February 2002 and was extended from Buona Vista to World Trade Centre to close up the link and to provide connectivity from the west to Sentosa, and it became the full Circle Line in the end.

Construction started in April 2002, and was supposed to be opened from 2006 and fully opened in 2010, with an estimated cost of S$6.7 billion, the Nicoll Highway collapse caused the construction of the Circle Line to be delayed to open from 28 May 2009 (the Stage 3 of which it is not affected by Nicoll Highway collapse), with full opening on 8 October 2011, at an escalated cost of nearly S$10 billion.[2] Due to the re-alignment of the Nicoll Highway Station to a new location, the station is only two-thirds the size of the original plan before the collapse, and located 100m away from the highway collapse site.[3] The decision was also made to open both Template:STN, andTemplate:STN stations (previously Thomson and West Coast), as a normal stations leaving the Template:STN closed, and there is only a middle track and emergency escape shaft.

Circle Line Stage 6

On 17 January 2013, the Land Transport Authority announced 'Circle Line Stage 6 which will close the circle, running between Template:STN and Template:STN. It will be a 4 km extension.[4] On 29 October 2015, the LTA announced the 3 station locations for the 'Circle Line Stage 6'. The stations are Template:STN, Template:STN and Template:STN. Construction of the line is due for completion in 2025.[5]

Incients

Nicoll Highway collapse

Main article: Nicoll Highway collapse

On 20 April 2004, a section of the tunnel being built for the Circle Line collapsed, apparently when a retaining wall used in the tunnel's construction gave way. This occurred near what was planned to become the Template:STN on the Circle line, not far from the Merdeka Bridge. The accident left a collapse zone 150m wide, 100m long, and 30m deep. Four workers were killed, with three more injured.

A criminal inquiry found the main contractor Nishimatsu Construction Company and joint venture partner firm Lum Chang Construction Company and their officers, as well as key Land Transport Authority officers responsible for the collapse. Several other officers and subcontractors were reprimanded and issued warnings in connection with the accident.

As a result of this accident, the first phase of the Circle Line, previously scheduled to open in 2008, was completed in 2009 instead. The affected station has been shifted about 100m away from the accident site and is now located at Republic Avenue.

This accident had also resulted in stricter safety regulations for the construction of all future MRT lines. The shifting of the Nicoll Highway Station also meant it can no longer serve as a terminus for the Bukit Timah Line, partially influencing the creation of the current Downtown Line.

Other incidents

On 16 August 2007, the Building and Construction Authority (BCA) issued a stop-work order and revoked the contractor's tunnelling permit after a 7m stretch of two lanes sank about 20cm, close to the junction of Telok Blangah Road and Alexandra Road in the evening, resulting in a halting of tunnelling works.[6]

A section of the road above a construction site near Holland Road caved in on the morning of 24 May 2008, creating a massive hole. The hole, directly in front of two private houses along Cornwall Gardens Road, measured 8 by 7 metres and was 3 metres deep. No one was injured, but the road was temporarily closed to traffic.[7]
