ROADS AND BRIDGES, JULY 1, 1913-DEC. 31, 1914. 23 



Gibson County, Milan, Tenn.— Work was begun on an earth road extending 

 north from Milan toward Cades on June 15, 1914, and completed August 18, 

 1914, with a loss of one day on account of bad weather and one day due to a 

 public holiday. The adjacent land is rolling and the soil consists of clay with 

 considerable sand. The road was graded with plow, scrapers, and grader to 

 a width of 36 feet in cuts and 32 feet in fills for a distance of 17,600 feet. 

 The maximum cut was 3.7 feet and the maximum fill 2.5 feet. The maximum 

 grade of 5 per cent was not changed. Considerable grubbing was necessary. 



The total cost of the work was $1,570.55, or $0,024 per square yard. The 

 principal items of cost were: Clearing and grubbing 5,555 square yards at 

 $0.0175 per square yard, $97.19; excavation and embankment at $0,020 per 

 square yard, $1,319.11 ; trimming slopes and ditches, $8.75 ; and superintend- 

 ence, $145.50. Labor was $1.25 and teams $3 per day of 10 hours. 



Erath County, Dublin, Tex. — Work was begun on a gravel-macadam road 

 extending north from Dublin toward Stephenville on October 29, 1913, and 

 continued until December 21, 1913, with a loss of 26 days on account of bad 

 weather. All work was stopped on December 21, 1913, on account of a con- 

 tinuous season of heavy rain. The nature of the soil and the excessive rains 

 (2.61 inches in 5 days) made work impossible. The adjacent land is rolling 

 with low hills, and the natural soil is black, sticky clay throughout. The road 

 was graded 30 feet wide in cuts and 21 to 24 feet in fills for a total distance 

 of 2,600 feet ; of this distance only 4,000 square yards were completely graded. 

 The maximum cut was 1.5 feet, the maximum fill 3.8 feet, and the maximum 

 grade on the old road of 3 per cent was reduced to 1£ per cent on the new road. 



At station 2+11 a culvert of two 30-inch corrugated-iron pipes 24 feet long 

 was built with stone masonry end walls, at a total cost for labor and material 

 of $180.40. At station 25+90 masonry abutments were built for a 16-foot 

 span bridge at a total cost of $250.69. 



In clearing, grubbing, excavation, and embankments, and fine grading, 

 $403.67 was expended, and on various work in preparation for surfacing with 

 gravel, $79.39. Free labor cost $1.25 per day of eight hours, hired teams, $2.50 

 per day, and county teams $2.40 per day.

A model highway system was reported .upon in October, 1913, involving the 

 improvement of 142 miles of road, and a bond issue amounting to $900,000 was 

 raised to complete the work. A department was organized by a representative 

 of the Office of Public Roads to make surveys, prepare plans, etc., and to super- 

 vise the work of construction. On January 1, 1915, about 80 miles of road had 

 been contracted for and nearly 60 miles completed. The contracts let also

 swing-bridges, 1 combination bridge, 14 timber culverts, 17 timber bridges, 1,540 

 linear feet of 12-inch concrete or tile-pipe culverts, 2,603 linear feet of 18-inch 

 concrete or tile-pipe culverts. The material for the bridges and culverts in- 

 cludes 2,547 cubic yards of concrete, 185,917 pounds of reinforcing steel, and 

 163,000 feet b. m. of timber. The work was planned in 16 divisions, whicb 

 are referred to herein as highways Nos. 1, 2, 3, etc. The total aggregate of
