The Dhaka Elevated Expressway is a complex infrastructure project composed of several key elements designed to enhance its functionality and durability, ensuring it meets the needs of one of the world’s most densely populated cities. The expressway’s composition includes: Dhaka Elevated Expressway Composition
Structural Components: These are primarily made of reinforced concrete and steel. The elevated structure relies on a series of pillars and viaducts that support the road segments above ground level. The use of high-strength materials is critical to withstand the heavy traffic load and environmental stressors such as monsoon rains.
Roadway: The expressway typically features multiple lanes in each direction to accommodate the high volume of vehicles. The road surface is constructed from durable materials designed for smooth and efficient travel, with adequate drainage systems to handle the heavy rainfall common in the region.
Interchanges and Exits: To facilitate the movement of traffic on and off the expressway, there are strategically located interchanges and exits. These are designed for ease of navigation and to minimize congestion, connecting the expressway with major roads and destinations in Dhaka. Dhaka Elevated Expressway Composition.
Safety Features: Safety elements include barriers and railings to prevent vehicles from leaving the roadway, as well as lighting for nighttime visibility. Emergency exit points and signs are also integral to the expressway’s design, ensuring quick response times in case of incidents.
Toll Collection Systems: The expressway is a toll road, featuring automated toll collection systems at various points. These systems are designed to minimize delays, using technology such as electronic toll collection to streamline the process for users.
Environmental Considerations: Given the environmental impact of such a large-scale construction project, efforts are made to incorporate green features, such as noise-reducing barriers and measures to limit pollution during the construction phase and beyond.
Monitoring and Maintenance Facilities: Continuous monitoring of the expressway’s condition is crucial. This includes surveillance systems to manage traffic flow and detect issues, alongside regular maintenance to ensure the expressway remains safe and operational.
By combining these elements, the Dhaka Elevated Expressway aims to offer a modern, efficient, and safe transportation route, reflecting significant advancements in Bangladesh’s infrastructure development efforts. Dhaka Elevated Expressway Composition
