(Satellite)

"The Sultan Abdul Halim Mu'adzam Shah Bridge (E28), popularly called the Second Penang Bridge (or Penang Second Bridge), is a bridge linking Penang Island to Penang Mainland. It is 24 km (15 miles) in length, with length over water of 16.9 km (10.5 miles). Its length over water is double that of the first Penang Bridge. Since its completion, it is the longest bridge in Malaysia. The Second Penang Bridge was officially opened to the public at around 12:01 am in the morning of 2 March, 2014. It was renamed by Prime Minister Datuk Seri Najib Tun Razak after Tuanku Abdul Halim Muadzam Shah, the Sultan of Kedah and the reigning Yang di-Pertuan Agong of Malaysia at the time of its inauguration."

New Second Penang Bridge ,Malaysia
The project team gave the second bridge several S-shaped curves along its 24km length. This was intended to keep motorists' attention on the road while driving and reduce accidents. The second bridge has seismic expansion joints – allowing the structure to move during an earthquake.

"Similar to the first Penang bridge, the Penang Second Bridge has a cable-stayed, mid-span of 240m [787'] and a clearance height of 30m [98'] above sea level. A dual-pylon, cable-stayed structure consisting of three spans was adopted for the main navigation spans. The high clearance allows large ships to pass under the bridge." The total cost was $1.37m, which was largely funded by China.

30m (98') is not a high clearance. The 1931 Bayonne Bridge was built with a clearance of 151' (46m). But a major project in the 21st Century increased that clearance to 215' (65m). And the St. Lawrence Seaway, which is now rather old, has a clearance of 151' (46m).

"All TENSA-MODULAR expansion joints are designed with a special seismic protection feature which allows transverse movements of up to 200 mm. Four of the TENSA-MODULAR expansion joints are Type LR-LS (featuring noise reducing surface plates), especially suitable for locations close to residential areas."
