3rd Mile Interchange

The project involved construction of: 2-cast in-situ single box prestressed flyovers with constant depth of 1.6m (Overpass A with 10 spans of 22m+8x24m+22m and Overpass B with 11 spans of 22m+9x24m+22m), 3-Overpass Ramps, 1-Underpass, 2-Underpass Crossovers, upgrading of the roundabout and widening of the surrounding slip roads. A 3m x 9m x 5m deep underground reinforced concrete pump sump with 3 numbers of submersible water pump with preset water level sensor are installed at the underpass to pump out the surface run-off water during rainfall to ensure the underpass is flood free.

1m diameter bored pile was adopted for the main flyover. While other foundation such as reinforced concrete pile and pad footing were used depending on ground condition encountered.
