(a) The department, with the approval of the Director of Finance, may make a loan or loans from the State Highway Account of federal funds made available to it pursuant to subparagraph (B) of paragraph (2) of subdivision (b) of Section 2423 of the Streets and Highways Code for purposes of advancing a project, or a portion of a project, that has been programmed, on or before February 17, 2009, to be funded by Chapter 12.49 (commencing with Section 8879.20) and that is ready to be obligated within 120 days of federal apportionment. The board, as defined in subdivision (a) of Section 8879.22, may request the department to make a loan or loans. The aggregate amount of the request shall not exceed the amount of the unsold bonds that the committee, as defined in subdivision (b) of Section 8879.22, has, by resolution, authorized to be sold, less any amount loaned pursuant to Section 8879.31 or 8879.79 or withdrawn pursuant to Section 8879.32. Any amount loaned shall be deposited in the fund, as defined by subdivision (c) of Section 8879.22, and shall be transferred to the appropriate account for the project, or portion of a project, being advanced. Contracts for projects to be advanced with loan funds shall be awarded within 180 days of federal apportionment. The loan or loans shall be repaid without interest to the State Highway Account from the proceeds of bonds sold pursuant to Chapter 12.49 (commencing with Section 8879.20). The board shall execute any documents as required by the department to obtain and repay the loan or loans.

(b) Federal funds made available to the department pursuant to subparagraph (B) of paragraph (2) of subdivision (b) of Section 2423 of the Streets and Highways Code, except for funds to be loaned to eligible projects described in Section 8879.52, shall be allocated in the manner provided in Section 188 of the Streets and Highways Code. A loan may not be made pursuant to subdivision (a) if it would necessarily result in the aggregate of those federal funds, excluding funds to be loaned to eligible projects described in Section 8879.52, being allocated contrary to this subdivision.

(c) Upon repayment of a loan made pursuant to subdivision (a), those funds are hereby appropriated to the department for use on projects in the state highway operations and protection program.
