Prayagraj Bypass (Allahabad Bypass) Route Map, Toll Plaza, NH-19 Status & Latest Updates (2026)
The Prayagraj Bypass Project (Allahabad Bypass) is an 84.708 km access-controlled highway developed by NHAI under the National Highways Development Project (NHDP). It connects Kokhraj to Handia on NH-19 and has been fully operational since November 2009. The bypass includes the 1.01 km Ganga Bridge near Jagatpur and serves as a vital segment of the Golden Quadrilateral corridor.
By successfully routing long-distance commercial freight transit away from the congested metropolitan center of Prayagraj, it plays a key role in reducing travel time and vehicle operating costs along the Delhi–Kolkata highway segment.

Corridor Alignment & Engineering Features
Toll Plaza Information
The Prayagraj Bypass is operated as a toll road managed by the National Highways Authority of India (NHAI). Mainline toll plaza operations are situated to manage regional traffic flow, utilizing modern electronic toll collection systems like FASTag for automated toll processing.
Ganga Bridge Engineering
The engineering highlight of the bypass is the mega bridge built across the Ganga River near Jagatpur. Spanning approximately 1.01 kilometers, the bridge structures rely on a balanced cantilever design constructed to bypass urban density while minimizing environmental disruption inside the riverbed.
Golden Quadrilateral Connectivity
As a critical bypass corridor, the highway links directly into the national Golden Quadrilateral highway system, which forms the primary road transport network connecting Delhi, Kolkata, Mumbai, and Chennai.
NH-19 Connectivity
The bypass handles commercial logistics along the National Highway 19 (NH-19) corridor (formerly NH-2), allowing heavy commercial vehicle traffic to route around Prayagraj city seamlessly.

Prayagraj Bypass Project FAQs
Yes, the Prayagraj Bypass is a toll road with tolling active for transit vehicles. Toll collection operations are managed by NHAI.
Toll collection is handled via dedicated toll plazas along the alignment, supporting FASTag and electronic toll collection.
Yes, it is a key segment of National Highway 19 (former NH-2), which forms part of the Golden Quadrilateral network connecting Delhi and Kolkata.
The bypass crosses the Ganga River near Jagatpur via a 1.01 km balanced cantilever bridge.
The National Highways Authority of India (NHAI) is responsible for the operations, maintenance, and management of the bypass.
Designed as a 4-lane access-controlled highway. Posted speed limits are determined by NHAI and local authorities.
The Prayagraj Bypass project relevant to the current Prayagraj Ring Road development is the Prayagraj Southern Greenfield Bypass, being developed by NHAI as part of the city's southern/inner ring-road system. It is designed to provide an alternative route around the southern side of Prayagraj and improve movement of through traffic.
The Prayagraj Southern Bypass route runs through three Phase-I sections: from Dandupur to Mahuwari, Mahuwari to Nababa urf Nibi Kala Uparhar, and Nibi Kala Uparhar to Khodaypur Kasgaon on the NH-19 corridor. The project therefore forms a southern bypass around the developed part of Prayagraj.
The current Prayagraj Bypass map should show the Southern Bypass alignment from Dandupur through Mahuwari and Nibi Kala Uparhar toward Khodaypur Kasgaon. The corridor connects with the existing NH-19 network and forms part of the wider Prayagraj Inner Ring Road system.
The Phase-I alignment of the Prayagraj Southern Bypass extends through three NHAI construction packages: design km 34.400-43.200, 43.200-50.860 and 50.860-64.763. The third package includes an interchange loop at NH-19 near Khodaypur Kasgaon.
The Phase-I Prayagraj Southern Bypass comprises approximately 31.44 km across its three construction packages: 8.8 km in Package 1, 7.66 km in Package 2 and 14.98 km in Package 3. These package lengths should not be confused with the older 84.7-km Prayagraj Bypass Expressway on NH-19.
The project is being executed through separate NHAI packages, so current records report costs by package rather than as one simple project figure. NHAI tender records show ₹514.69 crore for Package 1 and ₹600.62 crore for Package 3, while later government monitoring records report revised project costs for the individual sections. The figures should therefore be quoted with the relevant package and cost basis.
The Prayagraj Southern Bypass is under construction. NHAI records identify the southern bypass packages as under construction, and the Prayagraj district administration conducted an inspection of construction of the Prayagraj Ring Road (Southern Bypass) on September 2, 2026.
The Southern Bypass has moved beyond the proposal stage and is under active implementation. Package 2 and Package 3 are recorded as under construction, while Package 1 has also progressed into construction following its NHAI tendering and award process.
The latest official local update is the September 2, 2026 inspection of the ongoing Prayagraj Ring Road (Southern Bypass) construction by the Prayagraj district administration. Current project records continue to show construction activity across the southern bypass packages rather than a merely proposed alignment.
No. The older Prayagraj Bypass Expressway is the approximately 84.7-km controlled-access NH-19 bypass between the Kokhraj and Handia sides of Prayagraj. The current Prayagraj Southern Greenfield Bypass is a newer NHAI project forming part of the Prayagraj Inner Ring Road system on the southern side of the city.
