This section of US 67 was an extension of a 3.7-mile portion, previously designed by Klingner, that began 1.2 miles East of Jacksonville. The new expressway consisted of 6.5 miles of 4-lane pavement; a diamond interchange at Concord Road that included a structure carrying Concord Road over US 67; 22 access roads, frontage roads, service drives, and streets totaling 6.3 miles of reconstructed pavement; 500,000 cubic yards of furnished excavation; 14,000’ of culverts; and 37 light pole locations, including electric service installations. The project was constructed via five stages of construction.
