Release: NBER Macrohistory Database
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.
