Do we need the Cross Island Line? Can we do without it?
The Cross Island Line (CRL) will be an important part of our MRT network. It will provide a faster commute between the east and the west, from Changi to Jurong, stretching more than 50 km with about 30 stations. Nearly half of these stations will be interchange stations. Our preliminary estimate is that commuters from residential areas like Loyang, Pasir Ris, Hougang, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi and West Coast will make at least 600,000 trips on the CRL every day. This will place the CRL higher, in terms of capacity and usage, compared to the North East Line. The CRL will also significantly enhance the resilience of our network, as the CRL will connect with all radial lines to provide commuters with many more travel routes to their destinations.
Why can’t the government just go with the alignment that does not cut through the CCNR?To make an informed decision on the alignment option that best serves the public, the Government has to understand the total impact of both alignments, including on transport connectivity, engineering feasibility, the CCNR and the environment, as well as the nearby homes and families. It is for this reason that LTA is conducting an Environmental Impact Assessment (EIA) study, site investigation works, and an engineering feasibility study
In addition, there will not be any construction work on the surface level within the gazetted boundary of CCNR. For both options, construction will be undertaken by tunnelling method using a Tunnel Boring Machine that starts from outside the nature reserve (see diagram below).
Similarly, the ventilation shafts or facility buildings will be sited outside the gazetted boundary of CCNR.
Is the EIA report available online for public viewing? How can I give my views?
The first phase of the EIA report for the CRL is available on the LTA website for public viewing. Members of the public can email their views to LTA_CRL_CCNR_EIA@lta.gov.sg.
What was the consultation process like?
When LTA first announced the possible alignment of the CRL in 2013, nature groups raised concerns about the potential environmental impact on the CCNR. In response, LTA formed a working group, including representatives from NParks and nature groups, to serve as a discussion/consultation forum for the EIA study in the CCNR for the proposed Cross Island Line.
Since 2013, MOT, LTA and the nature groups have held many formal and informal meetings, including walkabouts in the CCNR with Senior Minister of State for Transport Josephine Teo.
Over the course of more than two years, LTA consulted the nature groups extensively in preparing for Phase 1 of the EIA report. For example, when studying the impact of the proposed site investigation works on the ecology and biodiversity of the CCNR, LTA’s EIA consultant took into consideration a study that the nature groups had done.
Separately, some residents living near the CCNR have expressed concern that the possible alignments may affect their homes. LTA has been engaging them by keeping them informed about the CRL study as well.
LTA will continue its engagement with stakeholders including the nature groups and residents in the area.
