This part of the corridor crosses a densely populated residential area around Tbilisi city, considerable number of mountains, landslides and ravines. The upgrading of the road required traffic capacity expansion into a dual carriageway, including artificial structures-bridges, tunnels, and retaining walls in a difficult topographic and geological conditions.
IRD Engineering performed the following activities:
- Alternative alignment analysis and feasibility study of the Natakhtari – Rustavi section, including developing alternatives for the section between Natakhtari and Jinvali, the Natakhtari Interchange and the rehabilitation plan for the existing Tbilisi Bypass;
- Detailed engineering design of Natakhtari – Rustavi and Natakhtari – Jinvali Sections, including the interchange at Natakhtari.
- Value for Money Analysis and development of an optimal financing strategy.
