SYSTRA IBT’s Role: Redesign and construction engineering for main span, independent checking for approaches.

Design-Bid-Build-Value Engineering

Main Span: 530 m (1,738 ft)
Total Length: 3,081 m (10,108 ft)
Width: 20.8 m (68 ft) (approaches)

The foundations consist of drilled shafts with 1.8 m (5.9 ft) and 2.5 m (8.2 ft) diameters.

The concrete superstructure for the cable-stayed spans consists of lateral concrete boxes connected with transverse diaphragms. The deck is supported by two planes of stay cables anchored along the edges. It is built-in balanced cantilever with traveling forms. The delta shape pylons are 135 m (442 ft) high above the roadway. The pylon legs are connected with a cross beam just under the bridge deck.

The superstructure for the approach spans consists of a single cell box girder with constant depth for the 45 m (147 ft) spans and variable depth for the 82 m (269 ft) and 125 m (410 ft) spans. The 45 m (147 ft) spans are incrementally launched while the 82 m (269 ft) and 125 m (410 ft) spans are built in balanced cantilever with traveling forms.

SYSTRA IBT was responsible for the following tasks:

  • Value Engineering Design, detailed design, construction drawings, and construction analysis for the main cable-stayed bridge.
  • Independent design check for the adjacent spans: incrementally launched 45 m
    (147 ft) and balanced cantilever (CIP) 82 m (269 ft) spans.
