The Penang Bridge is a cable-stayed bridge connecting the mainland at Seberang Prai to the Penang Island. The 13.5km bridge is the second longest bridge in Malaysia and was opened to the public on September 1985.
On 11th September 2011, a fire lasting approximately 5 hours caused by short circuiting of electrical cables affected a 80m stretch of the bridge, damaging the deck soffit and girders.
JTK Consult (JTK) investigated the extent of fire damage and as a remedial measure used carbon fibre plates to strengthen the structure to meet its original design intent. The fibre plates were placed in one continuous length, making this the longest single application of carbon fibre plates for strengthening at the time of the works. The performance of the remediated bridge was then monitored for 6 months.
