King Albert Park - Beam Launching

The beam for the new pedestrian overhead bridge (POB) linking both entrances of the King Albert Park station has successfully been launched yesterday. A single steel truss spans the across the length of both roads. The superstructure of Entrance B has begun to form up, while the main entrance has been cast up to the bridge mezzanine level.

Due to the inclined elevation of the existing temporary decked road above the canal, the clearance between the temporary Bukit Timah Road and the new bridge is estimated to be about 5m, with only about 500mm of clearance observed above a double decker bus. While this is within the legal 4.5m limit, temporary height precaution barriers have been installed by the project team along Blackmore Drive and Bukit Timah Road prior to the POB.

Mined excavation of the tunnel linking the station to the ventilation building across Dunearn Road had recently been completed by the MacDow team. Formwork for the ventilation building superstructure has commenced, and the gantry crane is expected to be demobilized in the coming weeks. The reinstatement of Bukit Timah Road is scheduled by year end.
