Project Overview
The Bilaspur–Pathrapali corridor is an important highway link in Chhattisgarh, serving regional passenger and freight movement. Translink was engaged to prepare the complete detail design, leading to coordinated Good-for-Construction (GFC) drawings and BOQs for the four-lane expansion.
The assignment required integrating surveys, traffic assessment, geometric design, pavement engineering, drainage planning, and structure design into a unified, execution-focused package.

Challenges
As with most long-corridor designs, the project required careful handling of varied terrain, integration of multi-source survey data, and consistency across numerous design elements. Some locations included ponded or low-lying areas where drainage levels demanded additional checks, while a few grade-separated locations required new structures to be aligned near existing assets without causing interference.
These considerations had to be balanced with routine design coordination and the need for clear, construction-friendly outputs.
Solutions
Translink adopted a structured and collaborative design approach, validating field inputs, refining geometry through iterative modelling, and developing a drainage strategy that responded to local ground behaviour.
Structural designs were prepared to maintain compatibility with existing infrastructure where required, using advanced modelling tools to ensure clearances, stability, and constructability.
Impact
Translink provided a stable, well-coordinated, and execution-ready blueprint for four-laning the corridor. Improved geometry, refined drainage planning, and integrated structural layouts help enhance safety, capacity, and operational reliability.
The project strengthens regional mobility and supports smooth implementation under NHAI’s development programme.
