Huacheng Dadao Station () and formerly Twin Towers Station () during planning, is a metro station of Guangzhou Metro Zhujiang New Town Automated People Mover Systems in Guangzhou, China.
 It is located at the underground of the interchange of Huacheng Avenue (), Zhujiang Road East () and Zhujiang Road West (), in Tianhe District.
 It started operation on 8 November 2010.
The 380 kV Ems Overhead Powerline Crossing is a power line crossing for two circuits on the Ems River South of Weener, Germany.
 It is mounted on two 110 m tall pylons with two crossbars.
 The length of the span is 405 m.
The Kalamata–Pyrgos–Patras Line is a power line running near Pyrgos, west of Amaliada, east of Gastouni, 1.5 km west of Lechaina and encircles to the north, the southern part of the plain and connecting with another line connecting from Megalopoli.
 This power line has several power stations including Pyrgos, Amaliada, Lechaina, Varda and Lappa.
 The power line has several branches including a 5 km long line to near Lappa.
 The line linking Kavasila and Zante passes near Kavasila, about 1 km south of Dimitra, south of Kastro, north of Loutra Kyllinis and into the island of Zante.
 Most of the line is underwater.
Osaki Channel Crossing is a power line crossing of the Seto Inland Sea south of Yoshina, Takehara in Japan, which was built in 1997 and runs to the Ozaki Power Plant.
 The Ozaki Power Plant is owned by Chugoku Electric Power Company and is situated on an island on the Inland Sea.
 It has a span width of 2145 metres.
 As at Chūshi Powerline Crossing towers with three crossbars are used.
The Pearl River, also known by its Chinese name Zhujiang and formerly often known as the Canton River , is an extensive river system in southern China.
 The name "Pearl River" is also often used as a catch-all for the watersheds of the Xi ("West"), Bei ("North"), and Dong ("East") rivers of Guangdong.
 These rivers are all considered tributaries of the Pearl River because they share a common delta, the Pearl River Delta.
 Measured from the farthest reaches of the Xi River, the Pearl River system is China's third-longest river, 2400 km , after the Yangtze River and the Yellow River, and second largest by volume, after the Yangtze.
 The 409480 km2 Pearl River Basin (珠江流域 ) drains the majority of Liangguang (Guangdong and Guangxi provinces), as well as parts of Yunnan, Guizhou, Hunan and Jiangxi in China; it also drains northern parts of Vietnam's Northeast Cao Bằng and Lạng Sơn provinces.
The Obstacle Collision Avoidance System (OCAS) is designed to alert pilots if their aircraft is in immediate danger of flying into an obstacle.
 OCAS uses a low power ground based radar to provide detection and tracking of an aircraft's proximity to an obstacle such as a power line crossing, telecom tower or wind turbines.
 This capability allows the visual warning lights to remain passive until an aircraft is detected and known to be tracking on an unsafe heading.
 This leaves the nighttime sky free of unnecessary light pollution thus decreasing public annoyance issues while improving the environmental habitat.
The Yangtze River power line crossings are overhead power lines that cross the Yangtze River in China.
 There are at least three power line crossings on the Yangtze River at Jiangyin, Nanjing, and Wuhu.
 The towers of the crossing in Jiangyin are among the highest in the world.
The 400 kV Thames Crossing is an overhead power line crossing of the River Thames, between Botany Marshes in Swanscombe, Kent, and West Thurrock, Essex, England.
 Its towers are the tallest electricity pylons in the UK.
An overhead line crossing is the crossing of an obstacle—such as a traffic route, a river, a valley or a strait—by an overhead power line.
 The style of crossing depends on the local conditions and regulations at the time the power line is constructed.
 Overhead line crossings can sometimes require extensive construction and can also have operational issues.
 In such cases, those in charge of construction should consider whether a crossing of the obstacle would be better accomplished by an underground or submarine cable.
The Pylons of Pearl River Crossing is a 500 kV power line crossing over the Pearl River in China's Guangdong Province.
 The power lines are suspended from 240 m tall towers.

Question: How tall are the towers for the power line crossing over the Zhujiang?
Answer: 240 m
