An 8-lane cable-stayed bridge being constructed over the river Zuari in South Goa, has taken engineering to new heights. This is the second longest and widest cable-stayed bridge in India; it will serve Expressway NH-66 that runs between Panaji and Margao over the Zuari river. While the bridge is 640m in length, the approach roads stretch from near the Bambolim crossing in North Goa to (near the) Verna industrial estate in South Goa, covering over 13km.

Design & Construction
The project comprises of 3 sections:

- an 8.2 km highway from GMC Bambolim to Goa Velha
- a new 1.08 km Zuari Bridge (Cortalim – Tiswadi)
- a 3.6 km highway to Verna.

Complete prestressing was applied on the spine structure and support system released and moved to the next span. With the help of wing lifters, cantilever wings were lifted and held in position for casting of in situ stitch joints between spine and wings. After adequate strength was gained of the cast in place joint, transverse prestressing was applied to complete construction of the superstructure.
Dextra’s involvement
For this massive project, Dextra has been supplying its popular parallel-threaded rebar splicing solutions Bartec for Fe 500 and Fe 600 Grade steel. More than 160K Bartec couplers are getting installed in the Pile cages, Pile caps, and Pylon. This is an iconic bridge project with Fe 600 grade steel as part of the Pile caps and Fe 500 grade steel in piles up to 48 meter deep. Pylon is 103 meters in height and designed with Fe 600 grade steel as well.

In addition to Bartec couplers, for the bridge’s precast segments, the contractors also opted for Dextra Post-Tensioning Bar Systems. These PT bars help the project’s stakeholders carry out erection of precast segments and casting of the segments on time and in a quality-controlled manner.
