J108 - Second viaduct span

Reader Alfred Yeo Chi Jin, a resident of Bukit Batok West, kindly sent us a series of images of the contract J108 launch gantry. Good progress has been made with a second span nearly completed. The second span starts where the first currently ends, with the segmental box girder that has been bonded with the viaduct pier. The other end of the span will be located at a movement joint pier which uses bearings to support the viaduct instead of being bonded to the segmental box.

The segmental box at the end of the second span will have a flared base to allow it to rest on the bearing. Movement joint piers will exist every few spans and allow for the viaduct to expand and contract. To date, we have only seen completed movement joint piers for single bound tracks and not for piers that will support twin bounds. However we assume that the design of such piers will have a crosshead that allows bearings to be supported. There are several such piers already built but without the crossheads completed yet - you should be able to spot them being slightly shorter than their fellow piers. Have you seen any thus far?

of the chosen name?
