Notes:               Series Is Presented Here As 3 Variables: (1) Original Data, 1939-46;
                     (2) Seasonally Adjusted Data, 1946-63; (4) Annual Data Only, 1946-63.
                     This Series Covers Public Construction Of Streets, Roads, Alleys,
                     Bridges, Vehicular Tunnels, Viaducts, Sidewalks, Curbs, And Gutters;
                     New Culverts And Extensions Of Old Ones; Right-Of-Way Drainage,
                     Erosion Control, Lighting, And Guard Rails; And Earthwork Protective
                     Structures In Connection With Road Improvements. The Annual
                     Value-Put-In-Place Data Represent Annual Expenditure Estimates
                     Prepared By The Bureau Of Public Roads. Monthly Data On Value Put In
                     Place For Federal-Aid Highways (Interstate And State) Are Based On Bpr
                     Monthly Estimates, Adjusted To The Level Of The Annual Expenditure
                     Estimates For This Category Of Highways. Monthly Data For All Other
                     Highways Are Based On The Annual Expenditure Estimates, Distributed
                     Monthly By Applying Seasonal Indexes Computed From Final Data For
                     Federally Aided State Highways. The Final Bpr Annual Estimates Do Not
                     Become Available Until Two Years After The Period Reported. Data
                     Published Before That Time Are Preliminary Figures Based On
                     Projections Made By The Bpr. The Procedure For Estimating Value Of
                     Highway Construction Put In Place Was Revised In 1963. In 1964 Data
                     Were Revised Back To 1946. The Revised Data Are Considered Comparable
                     With Data For Earlier Periods. The Constant Dollar Series Is Derived
                     From A Quarterly Cost Index Of The Bureau Of Public Roads,
                     Interpolated Monthly By The "Engineering News-Record" Index. For
