Both sides of the bridge are on reclaimed land and foundations are large diameter bored piles to bedrock.

Components in the Stonecutters Bridge:
The corrosion resistance of these steels is provided by the alloying element chromium; improved resistance is provided by the addition of 2 to 3% of molybdenum.
Deck
Steel was used on the deck of the main span. It is a twin-box girder arrangement. The box section deck provides convenient anchorages and has significant torsional properties.

Concrete was used on the deck of the back span.
