Flyovers, bridges, overbridges, underpasses, overpasses, and other technological marvels allow people, automobiles, and even trains to save time and effort. Bridges are often built over bodies of water such as rivers, but bridges are designed to offer a path for people and even automobiles over a railway. In this age of crowded traffic in metro centres, a flyover is a concept that permits roadways to be erected above highways to allow for the speedier flow of people and cars.
Here are the 15 interesting flyovers from around the world:
1. The Judge Harry Pregerson Interchange, USA
This Los Angeles bridge contains a High-occupancy Vehicle (HOV) or carpool lane as well as a Harbor Transitway. It is primarily a junction for two highways, the Glenn M. Anderson Freeway and the Interstate-110 (Harbor Freeway).
2. Gravelly Hill Interchange (Spaghetti Junction), UK
This asymmetric intersection connects the A38 (Tyburn Road), A38(M) (Aston Expressway), A5127 (Lichfield Road/Gravelly Hill), and a number of unmarked local roads. It spans 30 acres (12 hectares), serves 18 routes, and features 4 kilometres (2.5 miles) of slip roads, but just 1 kilometre (0.6 miles) of M6. It comprises 559 concrete columns spanning five storeys and reaching a height of 24.4 metres (80 ft). As a result of the addition of railway lines, three canals, and two rivers, the engineers had to raise 21.7 km (13.5 mi) of the highway.
3. High Five Interchange, USA
The High Five Intersection is a huge five-level highway interchange located just north of downtown Dallas, Texas. It connects the Lyndon B. Johnson Freeway (Interstate 635) and the Central Expressway (US 75), two important freeways with substantial rush-hour traffic, and it is the city’s first five-level stack intersection.
The term “High Five” relates to the five flyover ramps that stand above the landscape and handle left-turn operations, alluding to the celebration gesture.
The interchange is the height of a 12-story building[1], with 43 bridges split across five levels (the “High Five”), 710 support layers, and 60 kilometers of new roads.
4. Jane Byrne Interchange (The circle interchange), USA
The Dan Ryan, Kennedy, and Eisenhower expressways meet at this junction. This construction is an example of a ‘turbine interchange,’ as opposed to the normal four or five-level stack interchanges. The design has become more flattened. It is, nonetheless, well-known for its high traffic and congestion.
5. Tom Moreland Interchange, USA
The transition is a stack crossover. Spaghetti Junction is a five-level stack junction, not a standard four-level stack, because of a northeast-to-southwest ramp that runs above the fourth level of the interchange. Buford Highway/US 23, Chamblee–Tucker Road, Pleasantdale Road, and Northcrest Road all have extra ramps. Approximately 300,000 cars pass through the interchange daily. From Northcrest Road to I-85 south, it contains 14 bridges, the tallest of which rises 90 feet (27 m).
6. Hebbal Flyover, India
The 5.23-kilometer flyover was developed by Gammon India to relieve traffic congestion at the intersection of NH-7 and the outer ring road. Hebbal is a Bangalore assembly constituency region that represents the city’s northern terminal and is famed for its magnificent lake. The city has experienced continuous development and expansion. Throughout the day, the Hebbal flyover has become a bottleneck for all traffic movement from the city to the north and vice versa.
7. Visvesvaraya Flyover, India
The Visweswaraiah Flyover is the country’s longest flyover. The 11.6-kilometer flyover connects Mehdipatnam and Aramghar junction on NH-7, which leads to Rajiv Gandhi International Airport in Shamshabad. This flyover in India allows the public to detour with three up and down ramps at various locations, including Lakshmi Nagar Junction, Budvel Junction, and Aramghar Junction, and it features the latest technology of prefabricated segment and overhead grid launcher, making it suitable for the public. It also has a central lighting system.
8. Kathipara Junction, Chennai, India
The Kathipara intersection, in the southern Indian city of Chennai, is one of Asia’s largest cloverleaf interchanges. It relieves traffic congestion on four highways, including the Grand Southern Trunk Road and National Highway 45. Maduravoyal, located in Chennai, is an important cloverleaf intersection where the National Highway 4 and Chennai Bypass cross, which was constructed in 2010.
9. Hosur Road Elevated Expressway, India
The Electronic City Elevated Expressway connects Silk Board Junction and Electronic City in Bangalore, India, and is 9.985 kilometres (6.204 mi) long. BETL (Bengaluru Elevated Tollways Ltd) was in charge of the project, which was part of the National Highways Development Project and the Elevated Highways Project. It begins after the Central Silk Board overpass at Roopena Agrahara and continues up to Electronic City. It rises 17 metres (56 feet) over the BMIC flyover, making it Bangalore’s tallest flyover.
10. PVNR Elevated Expressway, India
The V. Narasimha Rao Expressway connects the Hyderabad International Airport with Mehdipatnam and is 11.6 kilometres long. Except at the two extremities, the expressway’s previous design did not have any entry or departure ramps. Only Mehdipatnam and Aramghar could be used to access the expressway (and vice versa). People from the neighboring communities could no longer use the highway. As a result, the flyover’s traffic was thought to be insufficient, rendering it useless. Three sets of Entry and Exit ramps were built when the design was updated. Lakshmi Nagar Junction, Budvel Junction, and Aramghar Junction are the three locations for the ramps.
11. East Coast Elevated Expressway, India
The East Coast Elevated Highway is a proposed elevated expressway in Chennai, India, that would be 9.7 kilometers long (6.0 miles). It goes along the Bay of Bengal’s coast, crossing the Adyar Estuary and passing via Chennai’s Broken Bridge. The Tamil Nadu Highways Department is constructing this corridor in two stages as part of a circular transportation network.
12. Qingdao Haiwan Bridge and Jiaozhou Bay Bridge, China
Jiaozhou Bay Bridge (or Qingdao Haiwan Bridge) is a 26.7 km (16.6 mi) long highway bridge in Shandong Province, China. It is part of the Jiaozhou Bay Connection Project, which spans 41.58 kilometres (25.84 mi). The bridge’s longest continuous stretch is 25.9 kilometres long.
13. Bang Na Expressway and Burapha Withi Expressway, Thailand
The world’s longest road bridge, the Bang Na to Bangpakong Expressway, goes through Bangkok. The $1 billion box girder bridge spans 55 kilometers and was completed in February 2000. At a height of 30 meters, the tolled bridge spans National Highway Route 34 (Bang Na-Bang Pakong Highway). The bridge crosses the Bang Pakong River in a minor segment. The bridge has six lanes and has a total area of 1.9 million square meters. It was built by a joint venture of Bilfinger + Berger and Ch. Karnchang for the Expressway & Rapid Transit Authority of Thailand (EXAT) (BBCD). A total of 1.8 million cubic meters of concrete were utilized in the building.
14. 6th October Bridge, Egypt
The 6th October Bridge is a high-rise roadway in Cairo, Egypt. The 20.5-kilometer (12.7-mile) bridge and causeway spans the Nile twice, connecting the city to Cairo International Airport on the east bank.
15. Binhai Flyover, China
The Binhai bridge in Tianjin, China’s northernmost municipality, is next on the list of the world’s most incredible flyovers. It connects the city’s port, the Tianjin Development Zone, and the historic urban center along a 5.3-kilometer stretch.
