Frequently Asked Questions

Common questions about National Highway 31

A: National Highway 31 (NH-31) stretches across 507 kilometers, establishing a critical connection between Unnao (Uttar Pradesh) and Bakhtiyarpur (Bihar). The highway passes through Uttar Pradesh, Bihar, featuring 1 key junctions that connect to regional road networks. It serves as a backbone for commerce and tourism, facilitating seamless movement across state boundaries.

A: Currently, NH-31 operates 1 toll collection points for infrastructure maintenance and development. The toll structure is designed based on vehicle categories: Light Motor Vehicles (Cars/Jeeps/Vans) are charged approximately ₹65-65, Light Commercial Vehicles and Buses ₹215-215, while Heavy Commercial Vehicles pay ₹320-320 per toll point. With mandatory FASTag implementation, you can enjoy contactless passage within seconds, avoiding queues at dedicated FASTag lanes. Pro tip: Maintaining sufficient balance in your FASTag account prevents delays and double charges.

A: As per the latest assessment (Updated: 2025-08-10), NH-31 boasts a 2-lane configuration with asphalt pavement, currently maintaining a fair condition rating. The relatively lighter traffic load contributes to reduced road wear, allowing NHAI to maintain excellent pavement quality with bi-annual maintenance schedules. Regular upkeep includes vegetation control, drainage maintenance, and safety barrier inspections, ensuring optimal driving conditions throughout the year.

A: NH-31 serves as the lifeline for 5 strategically important urban centers, creating an integrated economic corridor. This strategic corridor links Unnao, Faizabad, Gorakhpur, Muzaffarpur, Bakhtiyarpur, each contributing unique economic, cultural, or administrative significance to the region. The highway supports diverse sectors including agriculture produce transport, manufacturing logistics, educational institutional connectivity, and tourism circuits, making it indispensable for regional socio-economic development.

A: Planning your journey from Unnao to Bakhtiyarpur? Budget an average travel time of 12 hours for the 507km stretch. Under ideal circumstances—early morning start (5-7 AM), minimal traffic, favorable weather, and express driving—the fastest documented time stands at <strong>{highway.travelTime.fastest}</strong>. However, realistic journey duration fluctuates based on multiple variables: toll plaza wait times (pre-FASTag era could add 30-45 minutes), urban area congestion near Unnao, seasonal weather patterns (monsoons can add 20-30% more time), mandatory rest breaks (recommended every 2 hours), and meal stops. Smart tip: Leave early morning to avoid peak traffic, maintain 60-80 km/h average speed for safety, and factor in 1 toll stops even with FASTag.

A: NH-31 features comprehensive traveler infrastructure designed for comfort and safety during long journeys. Fuel stations from all major oil marketing companies—HP, Indian Oil, Bharat Petroleum, and Shell—are strategically positioned every 40-60 kilometers, with most offering round-the-clock service including diesel, petrol, and increasingly, EV charging points (CCS/CHAdeMO standards). For this extended 507km corridor, you'll encounter a diverse food ecosystem: multi-cuisine restaurants near Unnao and Faizabad, authentic highway dhabas serving regional specialties (North Indian, local state cuisines), branded food chains (McDonald's, KFC, Domino's) at major junctions, and highway hotels with 24-hour coffee shops. Premium fuel stations feature clean washrooms (often with baby-changing facilities), attached convenience stores (snacks, beverages, travel essentials), working ATMs (₹2000 daily limit typically), and first-aid kits. Emergency support infrastructure includes authorized vehicle service centers at key junctions, mobile mechanic availability through highway patrol contacts, and towing services registered with NHAI. Several stretches now have dedicated truck parking bays to prevent roadside parking hazards.

A: Emergency preparedness is crucial when traveling on NH-31. For immediate life-threatening situations, dial 112—India's integrated emergency helpline connecting you to police, ambulance, and fire services with GPS-based location tracking. For highway-specific issues, 1033 is NHAI's dedicated 24/7 Highway Helpline offering roadside mechanical assistance, accident reporting, crane/towing services (₹5-8/km typically), and real-time traffic updates. Medical emergencies requiring ambulance dispatch should use 108 (free service in most states). As NH-31 crosses 2 states (Uttar Pradesh, Bihar), emergency response jurisdiction varies by location. Highway patrol vehicles from respective state police forces conduct regular rounds, especially during night hours (8 PM - 6 AM). Pre-save these essential numbers with clear labels in your phone, and consider installing the NHAI's official app for one-touch emergency access and live location sharing with authorities. In case of vehicle breakdown, move to the highway shoulder (left side), activate hazard lights, place warning triangles 50-100 meters behind your vehicle, and wait inside the car (with doors locked) while help arrives. Never attempt repairs on the carriageway itself.

A: Absolutely, FASTag has been mandatory since February 2021 for all four-wheelers (including private cars) on NH-31's toll plazas. This Radio Frequency Identification (RFID) technology revolutionizes toll collection—your prepaid tag, affixed to the windshield, communicates with toll sensors for automatic deduction, slashing transit time from 3-5 minutes to under 5 seconds per transaction. The environmental benefit is substantial: reduced idling cuts fuel waste and emissions at toll points. Acquiring FASTag is straightforward: Purchase from 23+ issuer banks (ICICI, HDFC, SBI, Axis, Paytm Payments Bank, etc.) via their mobile apps, bank branches, or websites. Online marketplaces like Amazon and Paytm also sell pre-loaded tags (₹200-500 including security deposit). Alternatively, buy point-of-sale at any toll plaza on NH-31—installation takes 2 minutes. Crucially, link the tag to your vehicle's RC (Registration Certificate) for KYC compliance. The FASTag operates pan-India across all national highways and participating state highways—one tag, infinite journeys. Recharge is multi-channel: bank apps, UPI payments, NHAI's 'MyFASTag' app, NETC mobile app, or cash/card at toll plazas. Maintain a minimum ₹130 balance (2x highest single toll) to avoid penalty lanes and double charges. Check balance regularly through SMS or apps to prevent payment failures.
