The draft budget for the final section of the rail link to Dallas/Fort Worth International Airport in Dallas, US, is being reviewed by the Dallas Area Rapid Transit Authority (DART).
The project includes a section from Belt Line Station at Belt Line and State Highway 161 to Terminal A of the airport, and a Blue Line extension from Ledbetter Station to the UNT Dallas campus.
The proposed $1.25bn financial plan is to be carried out over 20 years.
The DART board is expected to approve the budget and financial plan on 28 September.
The Orange Line extension, I-3, is expected to be complete in 2014.
