Huitt-Zollars designed a PS&E package for two miles of six-lane, major depressed freeway construction. Design included two entrance and exit ramps with toll booths, up to eight lanes of continuous frontage roads, relocation of utilities, bridges and walls. The project involved both urban and rural storm drainage systems; four miles of retaining walls including cast-in-place, cantilever, and tied back wall systems; plus major prestressed concrete bridge overpasses at Josey Lane, Scott Mill, and Kelly Boulevard. Important features of the project involved Huitt-Zollars' extensive design coordination, and the use of cost-saving wall standards specifically developed for this and adjacent sections.
