ROB & Fly Over Bridge on SP Ring Road at Sanathal Junction, Ahmedabad

Location: Sanathal Junction, SP Ring Road, Ahmedabad Client: Ahmedabad Urban Development Authority (AUDA)

Casad Services: Bridge Construction, Urban Infrastructure Development

---

Project Overview This vital project involved the construction of a Road Over Bridge (ROB) and a Flyover Bridge at the bustling Sanathal Junction on the SP Ring Road in Ahmedabad. With a project cost of 92.00 Crore, this integrated infrastructure solution by AUDA aimed to significantly decongest one of Ahmedabad's critical traffic bottlenecks. The project enhances seamless traffic flow, improves road safety, and provides a crucial upgrade to the city's rapidly expanding urban infrastructure.

Casad's Scope of Work Our involvement in this project centered on the detailed structural components and construction methodologies employed to deliver this integrated ROB and Flyover solution.

• Detailed Design Review: Reviewing and ensuring the detailed design of all structural elements, including substructure, superstructure, and approaches, to meet specified performance criteria and safety standards.

• Construction of ROB Portion: Execution of the Road Over Bridge section (50.48 meters) over the railway line, involving specialized construction techniques to ensure minimal disruption to railway operations.

• Construction of Flyover Portion: Execution of the Flyover section (267.10 meters), including the casting and erection of multiple spans.

• Integration of Approaches: Seamless construction of the Bopal (337.572 meters) and Aslali (294.4 meters) approaches, utilizing appropriate road and embankment construction methods.

• Complex Superstructure Execution: Precise installation of 162 cast-in-situ girders (25.300m spans), 20 deck slabs (8.40m), and 2 PSC Box Girders (45m), demonstrating advanced construction capabilities.
  

Capabilities in Action This project showcases our robust capabilities in executing complex, integrated urban infrastructure projects, combining both Road Over Bridge and Flyover elements.

• Integrated Multi-Structure Development: Proven expertise in designing and constructing projects that combine different types of elevated structures, such as ROBs and flyovers, for comprehensive traffic solutions.

• Complex Superstructure Handling: Strong capability in executing diverse superstructure components, including cast-in-situ girders, deck slabs, and pre-stressed box girders, tailored for specific span requirements.

• Urban Junction Decongestion: Demonstrated success in alleviating traffic bottlenecks at critical urban junctions, significantly improving traffic flow and safety.

• Efficient Project Delivery: Ability to manage and deliver large-scale urban infrastructure projects, ensuring technical excellence and adherence to project timelines and budget.
