BRIDGE WORK. 



BRIDGES AND CULVERTS ON POST ROADS. 



On the post roads typical designs of culverts and bridges prepared 

 by the office were built wherever suitable for the location, and they 

 are described in the reports of the post roads. In cases where 

 typical designs did not fit the locations, special designs were made 

 in accordance with surveys of the sites, as follows: Alabama, 2; 

 Iowa, 2 ; Mississippi, 5 ; Tennessee, 3 ; Texas, 1 ; Virginia, 3. 



PREPARATION OF PLANS, BRIDGE INSPECTIONS, ETC. 



Typical designs were prepared for I-beam bridges with wooden 

 floors for spans from 12 feet to 40 feet, varying in length by 2 feet. 

 Bridge sites were inspected and special designs prepared, as follows : 

 California, 2; Indiana, 2; New Hampshire, 1; North Carolina, 12; 

 South Carolina, 6; Tennessee, 1; Virginia, 1. Final inspections of 

 the bridges referred to above were made in a number of cases for the 

 benefit of local officials. In several cases designs prepared by State 

 highway departments and bridge companies were examined and re- 

 ports made. Concrete abutments for a steel bridge at Stanley, N. C, 

 were erected under supervision of an office engineer.

 were made early in 1914 for cooperation between the Department 

 of the Interior and the Department of Agriculture, also between the 

 Forest Service and the Office of Public Roads, for the purpose of 

 bringing about the wisest possible expenditure of available funds
