Bridge Features
The Sultan Abdul Halim Muadzam Shah Bridge is designed based on the double “S” curvy concept due to the geological reasons.The numerous “S”-like curves along the 24 km stretch are a requirement under the Road Safety Audit.to prevent drivers from getting drowsy, discourage speeding and improve road concentration.

The Sultan Abdul Halim Muadzam Shah Bridge is the longest bridge in the world that installed with High Damping Natural Rubber (HDNR) Bearing.
an effective seismic isolation system that enables the bridge to withstand high intensity earthquakes. The bridge is the first in Malaysia to be installed with seismic expansion joints, which will allow movements during an earthquake.
