ment of 6,470 miles of road at an estimated cost of $91,495,797, and 

 on which $38,664,397 Federal aid was requested. Up to June 30, 

 1918, 580 project statements had been approved for 6,249.40 miles of 

 road, estimated to cost $42,278,770, and on which was requested $16,- 

 049,821 Federal aid. So that on June 30, 1919, there had been ap- 

 proved by this department project statements for a total of 1,316 

 projects, involvinfij 12,719.98 miles of road estimated to cost $133,- 

 774,568, of which ^$54,714,219 in Federal aid was requested. At the 

 close of the fiscal year, therefore, there remained to the credit of the 

 States an unallotted balance, including- the additional funds which 

 then became available, of $111,908,087. 



Agreements with State highway departments were executed during 

 the fiscal j-ear to cover 453 of the projects for which project stated 

 ments had been approved. The estimated cost of the projects cov- 

 ered by these agreements amounted to $41,598,209, of which amount 

 there was set aside in the Treasury $18,031,680 as Federal aid. At 

 the close of the fiscal year 1918 there had been executed a total of 

 224 such agreements of an approved estimate of cost of $14,820,633, 

 of which there was set aside in the Treasury $5,899,936. Thus, at 

 the close of the fiscal year 1919 a total of 677 agreements to cover 

 projects had been executed, involving a total approved estimate of 

 cost of $56,418,843, and a total of $23,931,617 Federal aid. The 

 projects for which agreements had been executed at the close of the 

 fiscal year call for the improvement of a total of 5,791.23 miles of 

 road. 



Under the terms of the Federal aid road act the apportionments 

 to the States for each fiscal year remain available for expenditure 

 iintil the close of the succeeding fiscal year, but it is construed that 

 funds covered by agreements are expended within the meaning of 

 the law. Each State had a sufficient amount of funds under agree- 

 ment at the close of the fiscal year to prevent its losing any part of 

 the funds apportioned to it. 



Statistical information is shown in the following tables as to the 

 status of Federal aid projects, the miles and types of roads included 

 in Federal aid projects, and the expenditure and construction of 

 roads during the fiscal year:
