In the coast of the province was built in 1937-1938 a section of the Litoranea Balbia, a road that went from Tripoli and Tunisia's frontier to the border of Egypt.
The project was stopped in the fall of 1942, leaving many infrastructures like stations and connection roads already done in the "Provincia di Tripoli".
The indigenous population was Arab, with some berbers in the Nafusa Mountains south of Tripoli and some thousands Jews and a few Maltese[7] on the coast.
According to the 1936 census, which allowed citizens to declare their ethnicity, Tripoli's native population was made up of 79.1% Arabs, 9.8% Berbers, 3.4% Blacks, 1.7% Turks and 6% Others.
[8] In the province of Tripoli thousands of Italians (called "ventimilli") moved to live in 1938 and 1939 and founded some agricultural villages (like "Bianchi",[9] "Giordani", "Oliveti",[10] "Marconi", etc..).
