North Line Extension

Atlanta, Georgia

(November 1998)


The Metropolitan Atlanta Rapid Transit Authority (MARTA) is constructing a 1.9-mile, two-station extension of the North Line from just north of the Dunwoody Station to North Springs. The extension will connect with the North Line segment from Buckhead to Dunwoody, which opened for service in June 1996. The extension will serve the rapidly growing area north of Atlanta, including Perimeter Center and north Fulton County. The 1.9 mile extension is now estimated to cost $463.18 million (escalated dollars) and includes 56 rail vehicles. The original total estimated cost for this extension as reflected in the FFGA was $381.3 million and included the purchase of 28 rail vehicles. Due to changed conditions, recent scope enhancements (outside the FFGA), and 28 additional rail cars, the total project cost is currently estimated at $463.18 million. However, the Federal commitment ($305.01 million) remains the same. Daily ridership on the rail extension in the year 2005 is estimated at 33,000 riders, including 11,000 new riders.


In December 1994, MARTA and FTA entered into a Full Funding Grant Agreement (FFGA) in the amount of $305.01 million in Section 5309 New Start funds for the extension from Dunwoody through North Springs. TEA-21 Section 3030(a)(3) authorizes the Atlanta North Line Extension for final design and construction. Through FY 1999, a total of $259.87 million in Section 5309 New Start funds has been allocated to this project ($231.5 million in Congressional appropriations and $28.37 million in prior year deobligated funds).

The expanded scope requirements are due to the need to address expected increases in estimated service levels, station parking enhancements, and rights of way impacts stemming from the proposed widening of the adjacent GA 400 freeway. Section 3030 (d) (2) of TEA-21 authorizes FTA funding for project scope changes, including the purchase of the 28 additional rapid rail cars from amounts authorized by the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991.
