Known as Palmetto Parkway, Interstate 520 extends eight miles northeast from the Savannah River to Interstate 20 by Mathis Lake. The road was first proposed in 1971.1 Split between two phases, the first opened to traffic on June 22, 2004 at a cost of $43 million between Laney-Walker Boulevard in Augusta and U.S. 1 in North Augusta.2 Phase one included a new bridge over the Savannah River. North Augusta City Council supported construction of a six-lane span, but GADOT officials did not back that capacity, and a four-lane span was constructed instead. Work commenced in August 2002.3
Two routes were studied in 2003 for the north end of the Palmetto Parkway. They included a direct tie in at the U.S. 25 & S.C. 121 (Edgefield Road) interchange (Exit 5) and a new interchange with Interstate 20, 4,000 feet east of Exit 5. The latter was selected to alleviate traffic concerns at U.S. 25 and minimize impact on area businesses.4 Completion of the $275-million Palmetto Parkway took place during a ribbon-cutting ceremony held on December 16, 2009.5
