Route predictions

Finally, here is our speculative map of the station locations for Eastern Region Line (ERL). We expect the announcement to be made sometime in August, so here are our take on the locations. Once again, we reiterate that these station locations are part of our prediction based on available information and site conditions, not the final location or announcement by relevant authorities.

Based on information that we have collected over the past few years, we have established the following parameters for ERL:
  1.  The line will be 13km long, and will be a continuation of the Thomson Line from Gardens by the Bay.
  2. There will be 10 stations, named E1 to E10, on the line. E10 on the eastern end of the line will connect directly to Changi Depot. The downtown line will also be extended by 1 station to E10, where it interchanges with the ERL
  3.  One of the stations within the section of E1 – E5 will be a future station.

Looking into the available space, construction feasibility and the locations of soil investigations done in the past 2 years, we have come out with 2 possibilities of the overall alignment of ERL. The 2 options differ by the locations of E3 and E4. These 2 scenarios are the result of conflicting locations of SI. We suspect that one of the 2 possible alignments for this section is an alternative proposal for comparison and costing purposes. Similar exercises had been done for Thomson Line prior to the official announcement of the station locations.

Expected alignment
We expect the alignment to run northwards from Gardens by the Bay towards Tanjong Rhu, where it will run along Tanjong Rhu Road, Meyer Road, swing up to Amber Gardens, and merge back to Marine Parade Road just before Parkway Parade. The line then runs along Marine Parade Road until Bayshore where it gradually merges with Upper East Coast Road. The advantage of this alignment is that it avoids most of the old beach and sea wall, and hence reduces complexity during construction.

Here’s a run through of the locations of the MRT stations.
