Padma Bridge connects Louhajang Upazila of Munshiganj and Zazira Upazila of Shariatpur and a small part of Shibchar Upazila of Madaripur, linking the less devoloped southwest of the country to tha northern and eastern regions. The bridge was inaugrated at morning on 25 June 2022 by the PM Sheikh Hasina. The bridge consists of 41 sections, each 150.12 m (492.5 ft) long and 22 metres (72 ft) wide, with a total length of 6.15 km (3.82 mi). The width of Padma Bridge is 18.18 m (59.6 ft) and the height is 120 m (390 ft).The construction cost of the Padma bridge is Tk. 30,193.39 crore. It is estimated that by 2022, the bridge will carry 21,300 vehicles per day in 23 districts of Bangladesh, which will increase to 41,600 by 2025. It will take 9+1⁄2 years to recover the toll from all of them.

This achievement marks the completion of all 16 stations along the Dhaka metro rail route, extending from Uttara North to Motijheel. The last two stations of the Dhaka metro line opened in the morning, and from now on, the metro rail service will make stoppages at all stations. What is the purpose of metro train?

A metro train runs within a city, and it is established with the aim of covering large distances in a short timeWho is funding metro rail Bangladesh?

Asian Development Bank and Korea will contribute to $US 5.1bn cost of southern section. The inaugural section of MRT Line 6, Dhaka's first metro line, opened on December 28 2022.Metro stands for Metropolitan. 1. Metropolitan area is usually a group of cities so closely mesh together (with many many businesses) that you can barely notice were one city-line ends and one begins. 2. Common name for the underground mass transit system in a city 

According to officials concerned, each train can run at a speed of 100 to 110 kilometres per hour with 2,300 passengers. The service is designed to carry 60,000 passengers per hour and half a million passengers per day. 

The Bangabandhu Tunnel is also known as Kornofuli Tunnel. There is a lot of facilities as it is the first Tunnel and an important tunnel of Bangladesh.

1.Efficiency and Time Saving: By providing a direct, uninterrupted route beneath the Karnaphuli River, the tunnel significantly reduces travel time between the northern and southern parts of Chittagong. This reduction in travel time translates to increased efficiency for commuters and businesses alike. Smart transportation solutions focus on optimizing travel routes to minimize delays and congestion, and the Karnaphuli Tunnel achieves this by offering a streamlined passage across the river.

2.Traffic Management: The tunnel contributes to smarter traffic management in Chittagong by diverting a significant portion of traffic away from surface roads and ferry services, which were prone to congestion and delays. By providing an alternative route that bypasses potential traffic bottlenecks, the tunnel helps to improve overall traffic flow in the city. Smart transportation systems often leverage technology such as traffic monitoring cameras, sensors, and data analytics to optimize traffic flow and minimize congestion, and the Karnaphuli Tunnel aligns with this goal by providing a more efficient traffic management solution.

3.Ntegration with Digital Infrastructure: Smart transportation solutions often involve integration with digital infrastructure to enhance user experience and operational efficiency. While the Karnaphuli Tunnel itself may not feature advanced digital technologies, its construction and operation likely involve elements of digital infrastructure, such as monitoring systems for safety and maintenance purposes. Additionally, the tunnel's integration with the broader transportation network, including roadways and traffic management systems, contributes to the overall smart transportation ecosystem in Chittagong.

4.Environmental Considerations: Smart transportation solutions often prioritize sustainability and environmental considerations. While the primary purpose of the Karnaphuli Tunnel is to improve transportation efficiency, it indirectly contributes to environmental sustainability by reducing vehicle emissions associated with idling in traffic congestion. By facilitating smoother traffic flow and reducing travel times, the tunnel helps to mitigate the environmental impact of transportation in Chittagong.

Overall, the Karnafuli Tunnel represents a significant step forward for smart transportation in Bangladesh by providing an efficient, technologically advanced solution to address traffic congestion and improve connectivity in Chittagong.

An elevated expressway is one where the entire expressway is elevated from the ground traffic level. They are built on piers connected by girders & deck slab. These roads allow for the easy flow of traffic above & don't interrupt the traffic flow below the expressway where there are junctions or crossings. One of the key factors contributing to the elevated expressway's success is its strategic location and connectivity. Serving as a crucial link between major commercial hubs and residential areas, the expressway has become a preferred route for commuters seeking to bypass the city's notorious traffic jams.In January 2011, the BBA signed a deal with Italian-Thai Development Public Company to build the Dhaka Elevated Expressway at a cost of Tk 8,703 crore. An elevated expressway is one where the entire expressway is elevated ffromrom the ground traffic level. They are built on piers connected by girders & deck slab. These roads allow for the easy flow of traffic above & don't interrupt the traffic flow below the expressway where there are junctions or crossings. The four-lane Dhaka Elevated Expressway route begins near Hazrat Shahjalal International Airport at Kawla and runs alongside the railway line through Tejgaon, Maghbazar, Kamalapur, and ends at Kutubkhali near Jatrabari along the Dhaka–Chittagong Highway.
