Supervision of construction
Dates
1996 - 1998 Project Data
A 2.5-km four-lane dual carriageway viaduct
37-m spans
Four ramps
Construction cost: US$ 20 million
The 2.5-km long, four-lane dual carriageway viaduct is constructed using precast segments throughout. Steel forms with finely ribbed liners produce a regular textured finish to all structural elements. The viaduct structures use precast shell-type segments with curved soffit supported on shaped piers, founded on large diameter bored piles in addition to three precast down ramps and one precast up ramp. The viaduct/ramp bifurcation is an integral part of the design philosophy that permits the ramp to appear as evolving naturally from within the main viaduct and shows the consistent logic that has been applied to also simplify construction.
Main Features
Proclaimed as a landmark structure, the Sirci Viaduct is the first of its type in India that uses segmental bridge technology.
The flyover is designed for construction over the busy existing Mysore road with minimal interruption to traffic and commercial activities.
