The Red Line is one of the primary routes of the Dubai Metro system in the United Arab Emirates. It begins at Centrepoint Station (formerly known as Rashidiya Station) in the east and terminates at Expo 2020 Station in the west. The line runs predominantly along Sheikh Zayed Road, traversing the main axis of Dubai’s urban development.
The initial segment of the Red Line opened on September 9, 2009, with ten stations in operation. Subsequent construction was completed and announced on April 28, 2010, with sixteen additional stations opening throughout the same year. By 2013, three more stations had been added, bringing the total to 29 stations with a total line length of 52.1 kilometers (approximately 32.4 miles).
According to the Roads and Transport Authority (RTA) of Dubai, the Red Line transported approximately 38.888 million passengers in 2010, with a daily average of 149,000 passengers. By 2013, the annual ridership had exceeded 88 million, with a daily average of approximately 243,000 passengers, reflecting significant growth in usage and transport demand.
Notably, the Red Line holds the Guinness World Record (certified in 2011) as the world’s longest fully automated metro line. It not only provides efficient public transit across Dubai but also stands as a symbol of the city’s modernization and smart infrastructure development.
The Setiawangsa–Pantai Expressway (SPE) is a 29.8-kilometre (approximately 18.5 miles) expressway traversing the Klang Valley region in Selangor and Kuala Lumpur, Malaysia. It begins in the north at Taman Melati and Klang Gates, connecting to Federal Route 28 (Kuala Lumpur Middle Ring Road 2), and extends southward to Kerinchi, where it links with the Sprint Expressway – Kerinchi Link and Federal Route 2 (Federal Highway), providing access to Pantai and the University of Malaya.
Running in a north–south alignment through the city of Kuala Lumpur, the expressway serves several key areas, including the Tunku Abdul Rahman University of Management and Technology (TAR UMT), Wangsa Maju, Setiawangsa, Ampang, the Tun Razak Exchange (TRX), and the Bandar Malaysia development corridor.
In addition, the SPE connects to the Kuala Lumpur–Karak Expressway, a major route to Malaysia’s east coast, further enhancing regional connectivity between Greater Kuala Lumpur and the eastern states. This expressway plays a strategically vital role in facilitating urban development and improving transportation efficiency in the region.
The Chongqing Qiansimen Jialing River Bridge is located in the heart of Chongqing. It begins at Shaanxi Road in Yuzhong District, connecting to the northern abutment of the Dongshuimen Yangtze River Bridge. The bridge passes beneath the Yuzhong Peninsula via a tunnel and exits near the famous Hongyadong scenic area. It then spans the Jialing River and ends at Nandajie in Jiangbeicheng.
The total length of the project is approximately 1.60 kilometers, comprising the main bridge and approach structures (collectively referred to as the Qiansimen Jialing River Bridge proper), the Yuzhong connecting tunnel, and a system of ramps linking to the surrounding urban road network on both riverbanks.
The main bridge is a single-tower, single-plane cable-stayed steel truss structure, with span arrangements of 88 meters, 312 meters, 240 meters, and 80 meters. The main bridge section totals 720 meters in length, with a main span of 312 meters. The Yuzhong connecting tunnel is approximately 700 meters long and features a four-lane, two-way design.
The Dongshuimen Yangtze River Bridge is a key transportation facility spanning the Yangtze River in Chongqing, China. It is a double-deck cable-stayed bridge integrating both road and rail functions, connecting Yuzhong District and Nan’an District. As the first bridge crossing the Yangtze River from the Chaotianmen area of the Yuzhong Peninsula, it plays a central role in the city’s core transport network. Together with the Qiansimen Jialing River Bridge, it forms the "Two Rivers Bridge" system, serving as a critical transportation hub in Chongqing’s central urban area.
The bridge adopts a twin-tower, single-plane cable-stayed design with a total length of 1,124.947 meters and a deck width of 24 meters. Its main span reaches 445 meters. The structure features a two-level layout: the upper deck accommodates a four-lane urban secondary road, while the lower deck carries the dual-track Chongqing Rail Transit Line 6.
The bridge’s towers are shaped with a smooth, streamlined “watch hand” (tissot-style) design, blending structural function with urban aesthetic appeal. The south tower stands at 172.61 meters and the north tower at 162.49 meters, making them prominent landmarks in the region.
