The MARTA board has chosen a route for a planned expansion of its rail system northward along Ga. 400 that runs along the west side of the highway, avoiding neighborhoods on the east side, according to ajc.com.
The route MARTA planners settled on would bridge Ga. 400 at a spot north of North Springs Station and south of Spalding Drive. A second crossover back to the east side of the highway would occur north of the Chattahoochee River, with the exact spot still to be determined, the web site says.
MARTA is laying the groundwork for potential expansions in metro Atlanta, including the Ga. 400 one that would extend its heavy rail line from the current North Springs terminus all the way to Alpharetta.
