Hewitt Contracting Co. of Columbus submitted the low bid for the first section of the proposed Atlanta Circumferential Route, as it was known in the 1950s. Hewitt would build a 4.5 miles of highway from the General Motors assembly plant in Doraville around to Chamblee-Tucker Road.
About the same time, in August 1959, Hugh Steele, Inc., of College Park, began work on a 6.3 mile section of the highway on the south side of Atlanta, from U.S. 29 in Red Oak over to U.S. 41 north of the Georgia Farmers Market.
Steele used thirteen DW21 scrapers, and two of them were equipped with the new Caterpillar Synchrotouch transmission, which allowed the operator to shift gears with the flip of a lever. The Caterpillar brochure described the Synchrotouch as “Split-second shifting for faster cycles. Another earthmoving first.”
All of the DW21s were equipped with Esco teeth, further improving earthmoving efficiency. Additionally, Steele used six D8 pushers, two D8 tractors with Kelly rippers for rock, three D8 dozers, two D6 dozers, three No. 12 motor graders, and a 955 Traxcavator.
On the north side MacDougald Construction built many miles of I-285, which was completed in 1969.
