Building the Circle Line (CCL) was a
feat that required innovations in design, engineering and construction. It took place in
challenging soil
conditions, a maze of underground structures, and under a densely packed surface of roads,
expressways and
buildings.
Proposals for the line began in the 1990s, and plans for the CCL evolved to:
- cater to growing public transport demand,
- distribute commuter traffic away from busy interchanges, and
- create a greater number of connections and faster journeys.
As its name suggests, the 30-station CCL is a circular rail line linking the North-South,
East-West and
North East Lines to the city.
