Egyptian President Abdel Fattah al-Sisi on Wednesday opened a suspension bridge over the Nile touted as the world’s widest, one of a series of military-led, megaprojects designed to improve infrastructure and provide jobs. The bridge, which crosses the Nile just north of central Cairo, is a key link in a highway stretching from the Red Sea in the east to Egypt’s northwestern Mediterranean coast, and is meant to help reduce congestion in the capital.
