ROAD MILEAGE. 
The total mileage of public roads at trie close of the year 1914 
amounted to 17,995, of which 2,830.47 miles, or 15.73 percent, were 
surfaced. Of the surfaced roads 829.16 miles were plain macadam, 
42.80 bituminous macadam, 362.77 shell, 1,163 sand-clay, 256.24 
brick, 42.5 gravel, 12 concrete, and 122 other materials, principally 
sand-asphalt. The State has 3,686 miles of graded and drained 
earth roads. 
In mileage of surfaced roads, Marion County stands first, with 200 
miles, or 22.22 per cent: Gadsden County second, with 185 miles, or 
46.25 per cent; Palm Beach County third, with 160 miles, or 44.44 
per cent; Orange Coun t yi our th, with 157 miles, or 48.3 per cent; Lake 
County fifth, with 150 miles, or 46.15 per cent; and Duval County 
sixth, with 144 miles, or 56.47 per cent. Six other counties have more 
than 100 miles surfaced and 10 counties report none. 
In 1909 the surfaced roads amounted to 1,752 miles, or 9.97 per cent, 
of the total, thus showing that during the 5-year period 1,078 miles 
were surfaced. 
The mileage statistics for the various counties are shown in Table 40. 
GEORGIA. 1 
By S. W. McCallie, State Geologist. 
Georgia has a land area of 58,725 square miles, a total road mileage 
of 80,669, and a population, according to the 1910 census, of 2,609,121. 
The State therefore has a population of 44.42 per square mile of 
area and 32.34 per mile of road, with 1.37 miles of road per square 
mile of area. Of the population in 1910, 79.4 per cent, or 2,070,471, 
was rural, thus indicating a rural population of 25.66 per mile of 
road. 
The surface configurations of Georgia vary from a low, level, almost 
featureless plain only a few feet above sea level to high rugged 
mountains attaining an altitude of more than 4,000 feet. The State 
is naturally divided into fire physiographic divisions : The Coastal 
Plain, the Piedmont Plateau, the Appalachian Mountains, the Appa- 
lachian Valley and the Cumberland Plateau. 
The board of county commissioners, in counties where such boards 
have been created, or the commissioners of roads and revenues, or 
the ordinary of each county, has jurisdiction over the roads therein. 
These officials, in many cases, appoint three district road commis- 
sioners for each road district in the county and the district road 
commissioners appoint one or more road overseers for their respec- 
1 The information contained in the tables [see Appendix] concerning the public roads of Georgia was 
collected by the State geological survey, in cooperation with the United States Office of Public Roads 
and Rural Engineering, largely by correspondence, but in some instances personal visits were necessary. 
The work was begun about the 1st of March, 1915, and completed in December, 1915.
