A bill to amend the Internal Revenue code of 1986 to repeal the provision prohibiting the crediting of interest to the Highway Trust Fund, to provide certain transfers to such Trust Fund, and to extend the expenditure authority for such Trust Fund, and for other purposes.

Amends the Internal Revenue Code to: (1) repeal the requirement that obligations held by the Highway Trust Fund be non interest-bearing; (2) appropriate additional amounts to such Fund and allow such amounts to remain available without fiscal year limitation; and (3) extend until March 31, 2011, the authority to make expenditures from such Fund (including the Mass Transit Account).
