This commuter line passes through downtown Fort Worth, Haltom City, North Richland Hills, Hurst, Colleyville, Southlake and Historic Downtown Grapevine into the north side of DFW International Airport (DFWIA) Terminal B. This project crosses the Trinity River and nine other bodies of water. The two existing stations, T&P and ITC stations, are shared by the Trinity Railway Express (TRE) and remained operational for the entirety of the construction phase. The stations included five parking lots, which used a total of 95,000 CY concrete, with bus bays, light poles, landscape islands, and bus shelters.
