DART Blue Line Extension

The DART Blue Line is an expansion of an existing track running from Garland to Rowlett. The Dallas Area Rapid Transit project includes 4.8 mi of light-rail double-track guideway running along an existing freight rail right-of-way. Existing right-of-way widths vary from 100 to 150 ft. The extension will be at-grade double track, will include fencing or other physical barriers along the right-of-way for security purposes and includes one station.

The project begins at the existing downtown Garland Station and extends to a new station proposed in downtown Rowlett. The scope of work includes multiple drainage and utility relocations and improvements; seven bridges (the largest of which is more than 2,600-ft long); ballast walls, cut walls and MSE retaining walls; and 8,300 lin ft of freight track realignment.
