India's rapidly expanding transportation network requires high-capacity corridors capable of supporting increasing traffic volumes, economic growth, and faster regional connectivity. To ensure consistency and safety in expressway development, the Indian Roads Congress introduced IRC 99:2013 – Manual of Specifications and Standards for Expressways.
The guideline establishes comprehensive standards for planning, designing, constructing, operating, and maintaining modern expressways. It serves as a key reference for engineers, developers, concessionaires, and government agencies involved in large-scale highway projects.
Today, advanced technologies such as AI expressway road condition monitoring, AI expressway survey India, and high-speed road AI compliance monitoring India are helping infrastructure agencies ensure that expressways remain safe, efficient, and compliant throughout their lifecycle.
Expressways differ significantly from conventional highways. They are designed for uninterrupted, high-speed travel with controlled access, grade-separated intersections, and advanced safety systems.
The objective of IRC 99:2013 is to create world-class expressways that:
The manual is particularly relevant for Public-Private Partnership (PPP) projects and major expressway corridors developed by agencies such as NHAI.
The guideline primarily applies to greenfield expressway projects designed exclusively for motorized traffic.
These facilities typically feature:
The code does not apply to urban expressways or roads located in mountainous and hilly terrain.
As agencies expand national highway networks, automated expressway survey AI India platforms are increasingly being used to support compliance with IRC 99:2013 requirements.
One of the most important sections of IRC 99:2013 focuses on geometric design, ensuring safe and efficient operation at high speeds.
The guideline recommends:
Expressways should generally be designed for:
These speeds help maintain efficient traffic movement while ensuring safety.
The code recommends a minimum ROW of 90–120 meters to accommodate:
IRC 99:2013 specifies:
Modern AI dashcam road survey expressway India systems can automatically verify lane conditions, shoulder quality, and roadway geometry during network-wide inspections.
To eliminate traffic conflicts and maintain uninterrupted movement, IRC 99:2013 requires the use of grade-separated infrastructure.
Common structures include:
These facilities improve safety while ensuring smooth movement for local traffic, pedestrians, and livestock.
Increasingly, road asset inventory AI platforms are helping authorities manage and monitor these structures across large expressway networks.
The long-term success of an expressway depends heavily on pavement quality.
IRC 99:2013 provides guidance for both:
Flexible pavement designs are selected based on:
Rigid pavements may be preferred where higher durability and lower maintenance requirements are needed.
Today, expressway pavement quality AI assessment tools help agencies continuously evaluate pavement health and detect deterioration before major failures occur.
Drainage plays a critical role in preserving pavement life and ensuring operational safety.
The manual recommends:
Proper drainage prevents:
Modern AI expressway road condition monitoring systems can identify drainage defects and water-related pavement distress through computer vision and automated inspections.
Road safety remains one of the primary objectives of IRC 99:2013.
The guideline includes recommendations for:
All signs and markings should comply with IRC standards and remain clearly visible under all operating conditions.
The code specifies the use of:
to reduce the severity of roadside crashes.
Lighting is required at:
Expressways should include:
Today, AI expressway safety survey platforms can automatically assess signage, barriers, pavement markings, and roadside assets to improve safety compliance.
IRC 99:2013 also focuses on user convenience and operational efficiency.
The manual recommends:
Electronic Toll Collection (ETC) systems reduce delays and improve traffic flow at toll plazas.
Facilities should be provided at regular intervals, including:
These amenities improve the overall travel experience while supporting long-distance mobility.
A major strength of IRC 99:2013 is its emphasis on quality control.
The concessionaire or contractor is responsible for:
The guideline also references international standards such as:
Modern AI expressway construction monitoring solutions enable continuous quality assessment, helping project teams identify issues early and maintain compliance.
As India's expressway network expands, manual inspection methods are becoming increasingly challenging.
Technologies such as automated expressway condition monitoring and digital expressway road asset inventory are transforming how agencies manage infrastructure.
These systems help:
IRC 99:2013 provides the foundation for developing safe, durable, and high-performance expressways across India. From geometric design and pavement standards to drainage systems, interchanges, safety infrastructure, and quality assurance, the guideline establishes a comprehensive framework for modern expressway development.
As transportation demands continue to grow, combining IRC-compliant engineering practices with AI expressway survey India and AI expressway safety survey technologies will enable smarter, safer, and more efficient highway networks.

IRC 99:2013 is the Indian Roads Congress manual that provides specifications and standards for planning, designing, constructing, and maintaining expressways in India.
The guideline recommends a design speed of 120 km/h in plain terrain and 100 km/h in rolling terrain.
AI can automate pavement inspections, monitor safety assets, assess road conditions, evaluate compliance, and support predictive maintenance across large expressway networks.
