It seems that LTA has adopted a shortcut mentality and forgotten that the detour only takes two additional kilometres. Reports in 2013 on the Cross Island Line showed that it is possible to avoid going through the Central Catchment Nature Reserve by taking a short detour. This detour was estimated to be between 1.7 and 2 km. A 2 km detour will mean 1 minute of additional travelling time at most. Surely this is a small price to pay for protecting our natural heritage.
