(2)  all other funding options available for the highway project will be insufficient to complete the project.
(c)  A highway project financed under this section may be financed through:

(1)  the department shall notify the comptroller of the establishment of the zone not later than the 30th day after the date the zone is established;
(2)  the comptroller shall:
(A)  at the beginning of each calendar year, estimate the increase in state sales tax revenue in the zone during the calendar year over the amount of state sales tax revenue in the zone during the calendar year in which the zone was established;

(C)  at the end of each calendar year:
(i)  transfer from the account to the department for the purpose of financing the highway project, an amount necessary to pay the costs of the project as described by Subsection (f), not to exceed the actual increase in state sales tax revenue in the zone during the calendar year over the amount of the state sales tax revenue in the zone during the calendar year in which the zone was established; and
(ii)  transfer to the general revenue fund any amounts remaining in the account after the transfer; and
(3)  the department shall terminate the zone and the comptroller shall cease making deposits and transfers under Subdivisions (2)(B) and (C) not later than the date specified under Subsection (e).
(e)  The authority to use revenue under Subsection (c)(2) expires on the earlier of:
(1)  the date all debt and other obligations are retired; or
(2)  the 35th anniversary of the date the highway project opens for revenue service.
(f)  Revenue described by Subsection (c)(2) may be used only for:
(1)  development and construction of the highway project; and
(2)  payment of debt incurred for the highway project.
(g)  Financing agreements for the highway project must contain provisions to allow the early retirement of debt using money from an economic impact zone under Subsection (d) or money appropriated by the legislature.
(h)  The maturity date of any bonds issued for the highway project may not be extended after the bonds are issued, including through the use of refinancing bonds and other refinancing agreements, unless the extension of the maturity date will decrease the total amount of interest to be paid until maturity.
