Explanation:

Width of Pavement or Carriageway:

  • The pavement width depends upon the number of lanes and the width of single-lane required. The lane width determines on the basis of the width of the vehicle and minimum side clearance.
  • The maximum permissible width of the vehicle as per IRC specification is 2.44 m.
Class of Road Width of Carriageway
Single lane 3.75 m
Two lanes, without raised kerbs 7.0 m
Two lanes, with raised kerbs 7.5 m
Intermediate carriageway ( except on important road ) 5.5 m
Multi-lane pavement 3.5 m per lane

Important Points

  • Intermediate carriageway is more than one lane but less than two lanes. This is only provided to allow manouvering.
