Penang Bridge
Official Website: http://www.penangbridge.com.my/

Ideas & initiated by the late Tun Abdul Razak, the 2nd Prime Minister of Malaysia in 1960s. The Bridge was planned during the term of 3rd Prime Minister, Tun Hussein Onn in 1970s. Built during the 4th Prime Minister, Tun Dr. Mahathir Mohamad in the 1980s and finally opened to traffic in 14 Sept. 1985.

Year Built : 1982
Year Completed : 1985
Project Duration : 3¾ Years
Bridge Design Name : Cable Stay Concrete Girder
Main Contractor : Hyundai Engineering & Construction. Co. Ltd, Korea
Consulting Engineer : Howard Needles & Tammen, Bergendoff Intl. Inc. SA/JK(SEA)


The Penang Bridge (Jambatan Pulau Pinang in Malay) is a dual-carriageway toll bridge that connects Gelugor on the island of Penang and Seberang Prai on the mainland of Malaysia on the Malay Peninsula. The bridge is also linked to the North-South Expressway in Prai and Jelutong Expressway in Penang. It was officially opened to traffic on September 14, 1985. The total length of the bridge is 13.5 km (8.4 miles), making it among the longest bridges in the world, the longest bridge in the country as well as a national landmark. Penang Bridge Sdn Bhd (PBSB) is the concession holder which manages it. The bridge was designed by a local Penang resident, Tan Sri Datuk Professor Ir. Chin Fung Kee, a well known authority in geotechnical engineering and former acting Vice Chancellor of the University of Malaya.



Before 1985, transportation between the island and the mainland was solely dependent on the state-owned Penang Ferry Service that runs between Butterworth and George Town.



Similar to the ferry services in Penang, toll is only paid when heading to the island. There is no charge for leaving the island.



Currently, the Penang Bridge is being expanded from 4 lanes to 6 lanes to accommodate the increasing traffic on the bridge. A proposal for a second bridge, the Penang Second Bridge, has been approved by the Malaysian federal government and included as one of the Ninth Malaysia Plan national projects. Construction work of the new Penang Second Bridge began in November 2008, and the target completion date is May 2012.

Stitching work on Penang Bridge
By DERRICK VINESH



An artist impression of how the Penang Bridge
would like after the expansion work.

WHILE most Penangites go to sleep, work to widen the Penang Bridge is being carried out late into the night and early hours of the morning to avoid disrupting traffic flow.

About 500 workers, including local contractors, Indonesian and Bangladeshi labourers, are at the famous Penang landmark from midnight until 6am daily, working together to put up additional lanes on both sides of the bridge.

Stitching work to merge the outer lanes with additional new lanes started 10 days ago.

“Motorists using the bridge may not see the workers as they are mostly working under the bridge,” said UEM Builders Berhad project director K. Preamakanthan.

“We have also placed temporary fences on the guardrails to prevent motorists from being unduly distracted by the ongoing work while driving on the bridge.”

Under the RM585mil bridge-widening project, the existing island-bound and Prai-bound dual-carriageway lanes, each measuring 8m wide, will have an additional 4.8m wide lane each.

Preamakanthan said only 700mm from the 3.65m-wide outer lane would be temporarily closed when stitching works were being carried out.

“We chose to do the work at night to avoid clashing with the heavy traffic flow on the bridge during the day,” he said.

He said the nine lay-bys on the bridge would be moved outside the additional lanes while 2m-wide demarcations would be drawn along the new lanes for motorcycles.

Preamakanthan said since widening works started in November 2006, concrete piles had been driven into the land and marine areas of the bridge between the midspan and Prai.

Piling work for the remaining stretch between the midspan and Penang island, he said, would be completed by August.

“We have started stitching work on a 1.6km-long stretch on the Prai-bound lane. Here, concrete columns have been vertically placed in be-tween large pre-cast concrete boxes, called crossheads,” he said.

Preamakanthan said in between two standing columns, a pair of 40m-long ‘I’ and ‘U’ shaped beams had been placed horizontally to rest on the crossheads.

These beams, he said, were manufactured at the company’s pre-casting yard located near the new toll plaza.

“The I and U-shaped beams, which each weigh 80 tonnes and 140 tonnes respectively, are hoisted using a gantry and placed on a multi-axel trailer to be transported to the designated sites.

“Two 350-tonne launching cranes onboard a 76m-long barge are deployed to pick up the beams and place them in position on the crossheads,” he said.

Preamakanthan said that so far, a total of 80 I and U-shaped beams had been put in place at a rate of two beams per night.

He said the company hoped to complete the laying of all 288 I-shaped beams and 296 U-shaped beams by early January. Work began last December.

Concrete mix will later be poured over the steel bars in a formwork (mould) placed on the beams to create a cemented deck slab.

New concrete guardrails would also be built on the outer side of the new lane, he added.

“The old guardrails will then be hacked to expose some parts of its steel frames that would later be overlapped on the protruding steel frames from the inner side of the new deck slab.

“Concrete mix will then be poured over these steel bars that are placed in a 1.2m-wide formwork to stitch both the old and new lanes,” he said.

Preamakanthan said the process of hacking, steeling and concreting at each stretch between two columns took about 18 days to complete.

He said that based on the rate of progress on the works, he was confident that the overall widening project would be completed by the Aug 24, 2009 deadline.

Huge jams after crane on bridge topples over
By : Phuah Ken Lin and Melissa Darlyne Chow
February 20th, 2009

A crane lifts the toppled crane, which was used to widen the Penang Bridge, yesterday. Two back-up cranes were required to lift the toppled crane, but one of the cranes broke down before it reached the scene, resulting in the delay. — Bernama picture

The partial closure of the bridge caused a traffic jam over a radius of 10km, causing motorists to jam up the ferry terminals to cross the channel.

GEORGE TOWN: A crane used for the Penang Bridge widening project toppled over near the mid-span of the bridge early yesterday causing a massive jam.

The chaos on the Jelutong Expressway on the island and Bayan Lepas Coastal Road lasted from the morning rush hour to about noon.

A Penang Bridge spokes-man said the 30-tonne hydraulic crane, which was being used on the third lane of the bridge, toppled over at Km3.6 of the mainland-bound lane about 3.15am.

A cable connected to the crane became entangled with a bridge pile structure as it was being used to lift a demolished parapet.

Northeast district police chief Assistant Commissioner Azam Abdul Hamid said traffic police dispersed traffic on the bridge by diverting mainland-bound motorists to the opposite lane.

The contra flow was activated at 9.35am to ease congestion.

The partial closure of the bridge caused a traffic jam over a radius of 10km causing motorists to jam up the ferry terminals to cross the channel.

Motorists were caught in bumper-to-bumper traffic across the island and on the mainland, particularly in Jalan Chain Ferry and Jalan Bagan Luar.

Nur Astikah Ismail, a civil servant from Butterworth, was late for work at Komtar due to the gridlock. "I was stuck in the jam at the ferry terminal from 7am and only reached my office at 11am."

The mainland-bound lane on the bridge was later closed temporarily to remove the crane.

Traffic flow returned to normal after the crane was removed around noon.

Penang Bridge said main contractor UEM Construction (UEMC) had required two cranes to lift the toppled crane, but one of the cranes broke down before it reached the scene, resulting in the delay while they waited for a back-up crane to arrive.

It said it took action to manage the traffic congestion, including providing continuous traffic updates via radio stations, while variable message signs and the online traffic information management alert were posted to inform motorists of the traffic situation.

The state government expressed outrage over the inefficiency of the Malaysian Highway Authority, Penang Bridge and UEMC to clear the toppled crane in the shortest possible time.

State Public Works, Utilities and Transportation Committee chairman Lim Hock Seng said many factory employees and businessmen were caught in the jam.

He was also affected.

"We are dissatisfied and angry over the attitude of those concerned who did not do the clean-up in the shortest possible time.

"They had about 31/2 hours before the rush hour started, and yet they could not clear the mess in time," Lim said, adding that they took eight hours to clear it.

"There could have been a lack of coordination among the three, resulting in the delay.

"What the state government can do now is state our stand to the Works Ministry, and ask them to take steps to prevent this from happening again."

To a suggestion that more ferries be added to the six in operation, Lim said this was not possible as, to get the seventh ferry up and running, about 100 crew members would have to be recruited.

"These range from captains to the traffic controllers right down to the engine runner. The ferry operators cannot do this as they are running up losses of tens of millions of ringgit every year."

Bridge’s third lane to be fully open soon
June 8th, 2009

BUTTERWORTH: The third lane on the Penang Bridge, excluding the mid-span area, will be fully open to traffic in a week.

State Public Works, Utilities and Transpor-tation Committee chairman Lim Hock Seng said the cable stay replacement work on the mid-span area would only be completed by August.

“Much of the bridge’s third lane is already open to traffic. Motorists should be patient until the third lane on the mid-span is made accessible as well,” he said.

Thousands of motorists have been caught in a bumper-to-bumper crawl at both ends of the bridge lasting up to eight hours from 4pm on Friday.

Lim said the congestion was due to an extraordinary surge in the number of motorists using the bridge.

“The high number of vehicles over this weekend was partly due to the school holidays and the public holiday for the Yang diPertuan Agong’s birthday,” he said.

Free towing service at Penang Bridge
Published: Saturday July 4, 2009 MYT 4:29:00 PM

BUTTERWORTH: Penang Bridge Sdn Bhd (PBSB) is now offering free towing services for motorcycles which break down or experience a flat tyre on the bridge.

Penang Public Works, Utilities and Transportation Committee chairman Lim Hock Seng said the move was aimed at preventing unscrupulous mechanics from imposing exorbitant charges to fix flat tyres on the bridge.

“Some mechanics have been charging between RM25 and RM30 to replace the inner tube of motorcycle tyres when the cost is only about RM10 to RM12 at workshops.

“Most motorcyclists pay the high charges as they have no other alternative when their vehicles stall on the bridge,” he said, adding that while the towing service was free, motorcyclists would have to bear their own repair costs.

Motorcyclists, he added, could call the PBSB Bridgeline at 1300-1300-03 or use the emergency telephone on the bridge to report their breakdown.

“A tow truck will be deployed to send the motorcycle either to PBSB-designated repair sites off the bridge or to the nearest workshop,” he said Saturday, adding that the service, which began last Wednesday, was available daily between 7am and 8pm.

PBSB deputy general manager Abd Rahman Hassan said it had received numerous complaints of unscrupulous persons scattering nails on the bridge to “make a fast buck”.

“With assistance from the police, we will continue to keep a close watch to reduce such activities,” he said, adding that there were 422 cases of motorcycle tyre punctures reported on the bridge in 2007 and 260 between January and September 2008.

New road to Penang Bridge
Wednesday July 22, 2009

The newly constructed slip-road from the North South Expressway to the Penang Bridge will be opened to traffic after midnight tomorrow.

In a statement, Penang Bridge Sdn Bhd (PBSB) deputy general manager Abd Rahman Hassan said the one kilometre long slip road at KM140.1, was part of the Penang Bridge widening project.

The new slip road is designed to ensure a smooth traffic flow from Juru heading towards the toll plaza area without disrupting the traffic going up north, he added.

Motorists heading towards the toll plaza are advised to drive on the correct lane and observe the directional signage to avoid overshooting the slip road.

However those who miss the slip road at KM140.1 are advised to make a U-turn at the Prai interchange.

He advised the public to be alert to all directional signages including the Variable Message notices.
