China's record-breaking Jiaozhou bridge 'is safe'

Jiaozhou

A reader submits this: BBC News says China's record-breaking Jiaozhou bridge 'is safe'.

Here the 'scare quotes' are entirely appropriate.

The chief engineer of the world's longest sea-bridge, in China, has denied claims that its construction was rushed to allow it to open on schedule.

Shao Xinpeng told state media that the Jiaozhou bridge, opened last Thursday, was safe and ready for traffic.

Chinese media reported finding incomplete crash-barriers, missing lighting and loose nuts on guard-rails.

Reports blamed workers' haste to finish the bridge in time for the Communist Party's 90th anniversary.

In a report earlier this week, a journalist from the state-run CCTV news channel unscrewed pieces of the guard-rails and showed that the lighting system was not working properly.

Construction workers told CCTV that it would take two months before finishing all of the projects related to the bridge.

But Mr Shao said the problems highlighted in the reports were not major.

"The status of secondary features does not affect the main project or the opening of the bridge," he told the state-run Xinhua news agency.

He added that the lighting system was only aesthetic.

The structure spans 42.4km (26.3 miles), connecting the eastern coastal city of Qingdao to the suburb of Huangdao, in Jiaozhou Bay.

State media say the bridge passed construction tests last Monday and it opened to traffic on Thursday.

It is 4km longer than the previous world record-holder, the Lake Pontchartrain Causeway in the US state of Louisiana.

There are also disputes about this being the longest bridge over water in the world, since it is curved, while the Lake Pontchartrain Causeway is straight, and so goes over a longer body of water. Wikipedia writes "There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others are the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list. " Also note many bridges are longer (and in China) but not over water.

I'm a bit surprised that anyone is building road bridges this long anyway. Considering that it'll take about half an hour to cross, the biggest safety issue probably revolves around drivers falling asleep. Wouldn't it be better to set up a roll-on/roll-off train service like the Eurotunnel Shuttle?
