Project Overview
State Highway 6 is a critical regional axis linking Ahmedabad’s growth zone with the Dholera Special Investment Region (DSIR). While the Ahmedabad–Dholera Expressway will serve long-distance and high-speed traffic, the Wataman–Pipali section acts as the primary gateway to DSIR for central and south Gujarat, supporting workforce movement, intermediate freight, and village-to-highway connectivity.
Translink was engaged to prepare the Detailed Project Report for four-laning, establishing a clear technical and financial roadmap for upgrading this corridor to meet its emerging economic role.

Challenges
The corridor carries highly mixed traffic—local, regional, and DSIR-bound—resulting in inconsistent operating speeds and safety concerns near built-up locations. Ribbon development along SH6 required careful widening strategies to balance four-lane requirements with minimal land impact. Geometric inconsistencies at curves, intersections, and village approaches needed correction to achieve a uniform design speed of four lane standard. Several cross-drainage structures were old and hydrologically inadequate, necessitating a fresh hydraulic review.
Pavement condition requiring a detailed material and structural assessment to determine appropriate rehabilitation strategy. The DPR stringent timeline also required synchronized survey planning, stakeholder coordination, and rapid integration of field data into the design framework .
Solutions
Translink developed the DPR using a context-sensitive and data-driven methodology. Traffic forecasting incorporated DSIR influence, regional freight behaviour, and future land-use changes. Geometric refinements were prepared through digital design tools like civil 3D to improve curvature, visibility, and junction performance. A pavement design strategy was formulated based on updated traffic loads and field investigations.
Each bridge and culvert was evaluated for structural soundness and hydraulic capacity, with rehabilitation or reconstruction proposed as required. All outputs were consolidated into HAM-compliant bid documents, enabling smooth transition into the procurement stage.
Impact
The proposed four laning strengthens SH6 as a dependable connection to DSIR, reducing travel time, improving safety near habitations, and enhancing freight movement from central and south Gujarat.
Better geometry, consistent riding quality, and upgraded drainage improve overall corridor performance, preparing the road for long-term economic activity driven by the region’s upcoming industrial ecosystem.
