DART adds 15 new stops to its service with the addition of the Green Line, which covers 28 miles of the North Texas area. The line extends north to Carrollton and as far south as Elam Road in Dallas.

Dallas DART riders said they are excited about the prospect of a faster more efficient means of transportation.

Ruth Rhodes said she has been using public transportation for 10 years and it’s a necessity to get her from her east Dallas home to her job west of town.

She said the Green Line will add another bus to her morning commute but will shave time off of it as well.

“Shorter transportation time and its probably more of a direct route,” said Rhodes.

Maurice Moore, 22, said he has used Dallas public transportation since he was a kid. Moore said he has a vehicle but prefers to save money and sees DART as an adventure-an opportunity to take him all over the city.

Moore said the Green Line will potentially open doors for his marketing business because it will allow him to see clients north of the city, as far away as Carrollton.

He said it’s addition to the North Texas area tells a story about where the Dallas-Fort Worth Area is headed.

“We’re growing and the demand for our population has changed,” said Moore.
