A new bridge in the mountains of southern Taiwan, boasting the nation’s tallest bridge pier at 99m, opened for traffic on Saturday.
Guchuan Bridge (谷川大橋) is the only link to the outside for the isolated mountain village of Wutai (霧台) in Pingtung County, and was completed after four years of construction in difficult terrain.
The bridge spans the valley of Ailiaobei River (隘寮北溪), and is 654m long and 10m wide, replacing an original bridge, known as Wutai No. 1 Bridge, which was destroyed by debris and floodwater during tMorakot Typhoon in August 2009.

A Directorate General of Highways official said the new bridge design addressed possible damage by flash floods during the typhoon season by increasing the distance between bridge piers, and only one pier set within the regular river flow.
That bridge pier stands at a height of 99m, which is equal to a 33-story building. It is now the highest bridge pier in Taiwan,” the official said, who declined to be named.
“The diameter of the bridge pier is about the same as the deck of the bridge at 10m. It is designed to withstand the erosion of the river’s rushing waters. Local residents should have no worries that the bridge piers will get washed out by flood waters,” he added.
The official said there were many problems that were overcome during the bridge construction.
“At times, in this mountain area we had strong winds of 5 to 6 [on the Beaufort wind scale]. Also we had thunder strikes and heavy rains. It was very difficult in those conditions. Due to this and other dangers, we had quite a few workers who got scared, walked out and quit,” he said.
“Eventually, we overcame all the tough challenges and were able to finish the project with a perfect record of ‘zero accidents’ across the 1,023 days of construction,” the official added.
With a total cost of NT$ 700 million (US$ 23.86 million), the concrete and steel structure links Wutai Township to Sandimen Township (三地門) of Pingtung County.
The two areas are inhabited mostly by Rukai and Paiwan Aborigines.
Wutai Township head Yen Chin-cheng (顏金成) said people are now no longer living on an isolated island.
“The new Guchuan Bridge is an important link for us to the outside world. It will benefit our local tourism and economic development,” Yen said.
He said that the bridge improves the lives of villagers, and also provides a safe access road for visitors heading into the mountains to enjoy the scenery, viewing of cherry blossoms in the spring, and making a trip to the area’s main tourist attraction, Shenshan Falls (神山瀑布).
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country. All of Taiwan except for Hualien and Taitung counties is to be under an “orange” air quality alert tomorrow, indicating air quality that is unhealthy for sensitive groups. In China, areas from Shandong to Shanghai have been enveloped in haze since Saturday, the ministry said in a news release. Yesterday, hourly concentrations of PM2.5 in these areas ranged from 65 to 160 micrograms per cubic meter (mg/m³), and pollutants were
