Charted on the following pages are the pertinent data with respect to financing of the Federal share of the expanded highway con

struction program.

The first chart shows authorizations as provided by the 1956 Federal-Aid Highway Act. The "ABC roads" (Federal-aid primary, secondary and urban extensions) authorizations were for only three years but continuance of that program is widely accepted as the intent of Congress. The chart points up the basic disparity between annual receipts and expenditures, which coupled with the so-called Byrd amendment and increased highway authorizations in the 1958 Federal-Aid Highway Act has caused the Trust fund to be short of the legislative authorizations.

The outlook through 1962 for financing the Federal portion of the program from the Highway Trust Fund is charted also. As of now, the Trust Fund surplus has been exhausted; the red area to the right indicates the cumulative deficit.
