A bill to amend title 23 of the United States Code to authorize the Secretary of Transportation to obligate the United States to pay from future year apportionments the Federal share of any highway on the Interstate System through the retirement of certain State bonds or other evidences of indebtedness used for construction of such highway.

Authorizes the Secretary of Transportation to obligate the United States to make payments from future apportionments from the Highway Trust Fund to a State in such amounts as are necessary to pay the Federal share of a completed highway project on the Interstate System if the State assures the Secretary that it will have sufficient funds to complete the project within five years through the issuance of bonds or other evidence of indebtedness. Requires that such payments received by such State be used only to retire such bonds or evidence of indebtedness.
