IRC classification and standard carriageway widths
The Indian Roads Congress prescribes standard lane widths based on roadway hierarchy and traffic density.
- Single-lane carriageway: Standard width of 3.75 metres, standard for rural agricultural and village link roads.
- Two-lane without raised kerbs: Standard width of 7.0 metres (3.5 metres per lane), common on State Highways and Major District Roads.
- Two-lane with raised kerbs: 7.5 metres width, utilized through urban and semi-urban commercial trading stretches.
- Multi-lane divided highways: Standard lane width of 3.5 metres per lane, separated by central median barriers on National Highways.
Rural road standards under PMGSY for agricultural freight
Pradhan Mantri Gram Sadak Yojana (PMGSY) establishes uniform engineering standards for connecting farming habitations.
- Carriageway width: Typically 3.75 metres of paved bitumen or concrete surface to accommodate tractors, combine harvesters, and milk tankers.
- Roadway (formation) width: Overall formation width of 7.5 metres in plains, including unpaved compacted gravel shoulders.
- Shoulder specifications: Minimum 1.875 metres of compacted earthen/gravel shoulder on each side for agricultural vehicle passing.
- Cross-drainage structures: Incorporates culverts and causeways to maintain all-weather connectivity during monsoon downpours.
Right of Way (ROW) and agricultural logistics impact
The Right of Way (ROW) encompasses the total land corridor reserved for future widening, side drains, and utility cables. Well-maintained rural roadways reduce transport times between farm gates and wholesale APMC mandis, minimizing transit damage to perishable produce and lowering freight transportation costs.

Common questions
What is the standard carriageway width of a single-lane road in India?

What are the road width dimensions for rural roads built under PMGSY?
PMGSY rural roads typically have a 3.75-metre paved carriageway and an overall formation width of 7.5 metres including compacted shoulders.
Why are properly compacted road shoulders important for agricultural freight?
Sturdy shoulders allow wide agricultural machinery like combine harvesters and tractor trolleys to safely pull aside for oncoming vehicles.
