  Since 2009, Bangladesh has embarked on a series of megaprojects. For instance, the 6.15 km long Padma Bridge was built for US$3.86 billion. The bridge was the first self-financed megaproject in the country's history. Other megaprojects include the Dhaka Metro, a mass rapid-transit system in the capital; Karnaphuli Tunnel, an underwater expressway in Chittagong; Dhaka Elevated Expressway; Chittagong Elevated Expressway; and the Bangladesh Delta Plan, designed to mitigate the impact of climate change.
