Total Length: 3 km (1.9 mi) of elevated roadway.
Typical span length: 66 m (216 ft) and 80 m (263 ft) long special span.

This superstructure consists of 3 km (1.9 mi) of elevated roadway, including mainline and access ramps. The structure consists of multiple lines of box girders. The box girders are supported by architectural piers supported on 1.05 m (3 ft 5 in) diameter CFA piles. Two types of precast segments were used on the project: single cell with internal struts maximum of 17 m (56 ft)-wide and single cell maximum 13.5 m (44 ft 4 in) wide. The 66 m (216 ft) long typical spans and 80 m (263 ft) long special spans were erected in balanced cantilever with a combination of overhead gantry, crane on ground and lifting frames on deck. Access ramps were built span-by-span on falsework.

SYSTRA IBT is responsible for the South Road Superway project as the Bridge Design Consultant, providing expertise in the design and construction engineering of the elevated guideway.
