If a toll project is in the territory of more than one local toll project entity, only the local toll project entity that first constructed toll projects may exercise the options and other rights under this subchapter. The local toll project entity exercising an option or other right under this section:
(1) may do so only with respect to the portion of the project located in the territory of that local toll project entity; and
(2) shall do so on behalf of another local toll project entity in whose territory the project will be located if requested by the other entity after the original entity declines to exercise its option.
