The Lucknow Road Plan || Highway Engineering

The Lucknow Plane (1981-2001)

Earlier two road development plans led to 2 shortcomings: 
(i) 1st two plans were not conceived to meet the needs of freight & passenger movement by road.

(ii) The plans were not part of the total transportation plan of the country.

 Features of Lucknow Plan

• Roads should be classified for India as follow:
 (a) Primary system : (i)  Expressways (ii) National Highways.

(b) Secondary system : (i) State highways (ii) Major District Roads.

(c) Tertiary system (Rural Roads) : (i) Other District Roads (ii) Village Roads.

 • Road length for the year 2001 should be 27,00,000 km giving a density of 82 km/100 sq. km.

• An all-weather road should connect all villages or groups of villages with a population of 500 and above by 2001. For villages less than a population of 500, the road network shall be so planned as to result in an all-weather road being available at a distance of less than 3 km in plain areas and 5 km in hilly terrain.

• Expressways should be constructed on major traffic corridors to provide speedy travel.

 • National Highways should form a square grid of 100 km x 100 km.

• State Highways should be extended to serve district headquarters, sub-divisional (taluka) headquarters, major industrial centres, places of commercial interest, places of tourist attraction, major agricultural market centres and ports.

• The Major District Roads should serve and connect all towns and villages with a population of 1,500 and above.

• The other District Roads should serve and connect villages with a population of 1,000.1,500.

• Energy conservation, environmental quality of roads and road safety measures were also given due importance in this plan.

• Selection of specifications should be done on the basis of 
(i) their amenability to stage construction.
(ii) the need to adopt appropriate technology .
(iii) the use of local materials .
(iv) the use of soil-stabilization techniques .
(v) the use of alternate binders .
(vi) the use of cement concrete pavements wherever economically feasible and .
(vii) the need to conserve bitumen.

Following formula give the lengths of various classes of roads as per the above guidelines:

1. Length of NH (in kin) =  (area/10000) = (area in sq.Km/50)

2. Length of SH (in km) = (area in sq.Km/25 )

or Length (in km) = 62.5 x Number of towns with population above 5,000 – (area in

3. Length of MDR (in km) = (area in

or Length (in km) = 90 x Number of towns with population above 5,000

4. Total road length (in km) = 4.74 x Number of villages and town

5. Rural Road Length (in km) = This can be calculated by finding the total road length and subtracting the other categories.
