Roads

Of the 47,800 miles of road, in 1969 about 6,000 miles--or 14
percent--were considered modernized. A little more than one-third had
gravel or crushed stone to harden them, and almost exactly one-half had
unimproved dirt surfaces.

About 7,600 miles were nationally maintained and included the greater
portion--5,200 miles--of those in the modernized, improved category.
Only about 1,400 miles of the local roads were modernized, and less than
one-half of them had hardened surfaces. According to government planning
reports, the road network is considered adequate in size, and all that
can be allocated to it will be applied to its modernization. Motor
transport was nearly negligible until after World War II, but between
1950 and 1969 it assumed importance that rivaled the railroads in both
cargo and passenger traffic.
