the scenery changes from tree-lined and park-like to cut-away hillsides covered with invasive kudzu vines and naturalized mimosa trees. this is the result of the 1990s widening to six lanes plus a raised median, with no replanting done except in the median. upon reaching paper mill road, the steep climb levels off and heavier local traffic begins, passing lower roswell road at parkaire and then roswell road (georgia 120 from marietta), the major crossroads of east cobb, and one of the county's most-traveled and most accident-prone intersections. it is also a major retail business district known as merchants walk, for its original shopping center. north of here, it becomes residential and goes back to four lanes and a landscaped median, passing sewell mill road, post oak tritt road, and then coming to shallowford road (not the same as another shallowford road in atlanta), which is an east-west arterial road (connecting with sandy plains road and the city of roswell). this intersection is a retail business district known as shallowford falls. the road continues north as a neighborhood street in the chimney lakes neighborhood (the location of the actual "shallowford falls"), finally ending at childers road.
