In a historic infrastructure milestone for Rajasthan’s transport network, the Rajasthan longest bridge Banas River project at Gahlod in Tonk district has been completed and readied for regular vehicular traffic. Spanning a monumental 3.34 kilometers, the high-level bridge ends decades of seasonal isolation for over two hundred rural habitations, establishing seamless year-round connectivity between Tonk, Ajmer, and the Jaipur metropolitan fringe.

- Project Cost & Funding: ₹134.74 Crore sanctioned under the Central Road and Infrastructure Fund (CRIF).
- Structural Configuration: 50 prestressed concrete spans measuring 40 meters each.
- Load Test Results: Successfully withstood 243 tonnes of static load across five stages with an exceptional 92% elastic recovery.
- Key Beneficiary Regions: Peepalu, Malpura, Todaraisingh, Diggi, Phagi, and Ajmer.
Engineering Feat: Technical Specifications of the Gahlod Bridge
Executed by the Public Works Department (PWD) National Highway and Bridge Wing, the Gahlod project sets a new benchmark in civil engineering across seasonal river basins in Western India. Below is the official technical breakdown:
| Engineering Parameter | Official Specification | Operational Benefit |
|---|---|---|
| Total Length | 3.34 km (3,340 meters) | Rajasthan’s longest elevated river crossing |
| Superstructure Spans | 50 Spans @ 40m each | Allows unhindered high-velocity monsoon river discharge |
| Carriageway Width | Two-lane with paved shoulders | Accommodates simultaneous two-way multi-axle freight |
| Load Testing Capacity | 243 Tonnes (92% recovery) | Far surpasses the 85% national IRC safety benchmark |
| Funding Authority | CRIF (Ministry of Road Transport) | Central grant executing critical state arterial corridors |
Decades of Monsoon Misery Ended: Ending 70 Km Detours
For over four decades, residents of Tonk and Ajmer districts faced severe logistical hardships during the four months of the southwest monsoon. The old low-level submersible causeway at Gahlod would submerge under 8 to 15 feet of water whenever the Banas River swelled with runoff from upstream Rajsamand, Bhilwara, and Bisalpur Dam releases.
During submergence periods, daily commuters, farmers transporting perishables, ambulances rushing critical patients to tertiary hospitals, and students heading to educational institutions were forced to undertake grueling detours of 50 to 70 kilometers via Malpura or Tonk city. The new high-level structure stands towering above the maximum recorded flood level (HFL), ensuring 365-day uninterrupted vehicular transit.
Strategic Connectivity: Linking Agricultural and Mining Corridors
The Gahlod bridge plays a transformative role in regional freight logistics:
- Agricultural Supply Chains: Tonk and Todaraisingh are major production hubs for mustard, wheat, pulses, and tomatoes. The bridge slashes transit time to the Jaipur Muhana Mandi and Ajmer wholesale grain terminals by over 90 minutes.
- Industrial & Mineral Transport: Provides a heavy-duty bypass for granite and silica sand haulage trucks operating from the central Rajasthan mineral belt toward the National Capital Region (NCR).
- Synergy with Southern Rajasthan: This engineering milestone complements major transportation upgrades linking Mewar and central Rajasthan, including the recently launched Surat Udaipur Vande Bharat Express and ongoing arterial bridge projects across the state.
Rigorous Five-Stage Structural Testing
Before issuing final safety clearances, structural engineers subjected the Gahlod Bridge to stringent testing over 72 hours. Six fully laden multi-axle dumpers carrying crushed aggregate weighing a cumulative 243 tonnes were stationed at mid-span positions.
Deflection sensors recorded an elastic recovery rate of 92%, easily exceeding the 85% requirement stipulated under the Indian Roads Congress (IRC) bridge codes. With structural integrity certified, state authorities are finalizing the formal dedication ceremony schedule.
Frequently Asked Questions (FAQ)
Which is the longest bridge in Rajasthan?
The 3.34 km Gahlod High-Level Bridge over the Banas River in Tonk district is currently Rajasthan’s longest bridge, featuring a 2.0 km main bridge and 1.34 km of approaches.
What was the total construction cost of the Gahlod Bridge?
The bridge was constructed at an estimated investment of ₹134.74 crore, financed through the Central Road and Infrastructure Fund (CRIF).
Which districts and towns are connected by the Banas River Gahlod bridge?
The bridge directly connects Tonk and Ajmer districts, providing vital transit for Peepalu, Malpura, Todaraisingh, Phagi, Diggi, and surrounding rural habitations.
How does the new bridge help during the monsoon season?
Previously, the old causeway would submerge during floods, forcing commuters to take 50 to 70 km detours. The new high-level bridge stands above the highest flood level, guaranteeing uninterrupted year-round connectivity.
What is the load-bearing capacity of the Gahlod Bridge?
The bridge has been officially tested and certified for a load capacity of 243 tonnes, registering a 92% structural recovery rate under IRC standards.
