Isa Town Gate, Kingdom of Bahrain

Synopsis:
Construction engineering, erection stress analysis and geometry control.
Contractor:
NASS Construction W.L.L.
End Client:
The Bahrain Ministry of Works roads directorate

The Isa Town Gate interchange was an existing roundabout with a five-leg junction in an urban setting with two major highways: Sheikh Salman Highway and Al Estiqlal Highway.

The project modifies the existing Isa Gate roundabout into a three-level grade-separated interchange. The flyover consisted of two non-parallel curved bridge decks 2.4 km long of glued segmental prestressed concrete viaducts.

Tony Gee worked with the largest locally based Bahrain contractor NASS Engineering to resurrect the stalled project. We provided assistance with the construction engineering, erection stress analysis and geometry control for the two segmental prestressed concrete viaducts.
