Texas Transportation Code - TRANSP § 284.067. Projects Extending Into Other Counties

(a) A county may not construct or acquire a project that is financed under this chapter and any part of which is in another county until the commissioners court of the other county adopts a resolution consenting to the construction or acquisition.

(b) A part of a project that has not been designated as part of the state highway system and that is not a turnpike project as defined in Chapter 361 is a part of the county road system of the county in which the part is located.  A law relating to the maintenance and operation of a county road applies to a project constructed or acquired under this chapter to the extent the law does not conflict with this chapter.

(c) Any county into which the project extends, by condemnation or another method under general law, may acquire the property necessary for the project, except that a county may not condemn property in another county until after the resolution required by Subsection (a) is adopted.  The county issuing the bonds may use the bond proceeds to acquire property necessary for the project in any county into which the project extends.

(d) Payment of the purchase price, award, or other cost of the project may be on the terms to which the commissioners courts of the county issuing the bonds and the other county or counties agree.  Proceeds from bonds issued under this chapter may be used to pay a cost incurred under this section.

(e) Two-tenths of one percent of the toll revenue shall be shared equally between the permanent school fund and the General Land Office.  The General Land Office shall use its share for the acquisition of real property in a natural state in the county of the project.  The acquired land shall be maintained in a natural state.
