Overview

Zachry Construction Corporation was awarded the I-20 widening project in Lexington County, South Carolina to design/build an approximately 11-mile stretch from four to six travel lanes ranging from Mile Marker (MM) 60.6 west of US378 to MM 49.8, west of Longs Pond Road. The widening shall consist of one additional travel lane in each direction, which shall be constructed toward the median.  The new lanes will start at the end of the existing pavement. 

 Construction began in the fall of 2016 and the design process is still underway. The 11-mile project consists of constructing new Portland cement concrete pavement (PCCP) median travel lanes and reconstruction of existing lanes. Crews will place 180,000 cubic yards of new Portland cement concrete pavement (PCCP) in the new median lanes and reconstruction areas. The project also involves the construction of a new median bridge; a mile-long section of noise wall; 36,100 linear feet of concrete median barrier; and the removal over 325,000 square yards of existing concrete pavement.
