The widening of roads in the old districts of Manama and the development of a national network linking the capital to other settlements commenced as early as the arrival of the first car in 1914. The continuous increase in the number of cars from 395 in 1944, to 3,379 in 1954 and to 18,372 cars in 1970 caused urban development to primarily focus on expanding the road network, widening carriageways and the establishment of more parking spaces. Many tracks previously laid in the pre-oil era (prior to the 1930s) were resurfaced and widened, turning them into 'road arteries'. Initial widening of the roads started in the Manama Souq district, widening its main roads by demolishing encroaching houses.
