To the east, a bridge connected Manama to Muharraq since 1929, a new causeway was built in 1941 which replaced the old wooden bridge. Currently there are three modern bridges connecting the two locations. Transits between the two islands peaked after the construction of the Bahrain International Airport in 1932. Ring roads and highways were later built to connect Manama to the villages of the Northern Governorate and towards towns in central and southern Bahrain.
