During this eleven-year period serious efforts were made to create a national road network using an investment of sixty million gold francs borrowed from the Italian Kingdom. During the ten-year period between 1929–1939 850 km of main roads, 456 km of secondary roads, 4,062 small bridges 10,250 miles long, and seventy-six major bridges 2,050 miles in length were constructed. This period also introduced the construction of a sewage network, and, for the first time, money was invested to build segments of roads in the northern part of Albania. The most important roads were: Shkodër-Puka, Mat-Bishop Bridge, Krujë-Mat, Tirana-Elbasan, Lushnjë-Mbrostar, Korçë-Burrel, Burrel-Dibër, Tiranë-Shijak-Durrës, Tiranë-Ndroq-Durrës, and Tiranë-Krrabë-Elbasan. Engineers from Europe were employed to complete these projects. In 1938, the value of investments reached 150 million Albanian Lek (1961 currency prices). On the eve of the fascist invasion, Albania had 300 trucks, 20 buses, and 200 cars and pickups.
