Issues in Indian Cities Due to Increasing Coverage of Highways: A Case Study of The Sriperumpudur ? Poonamalle Stretch in NH4

In 1947, during the year of independence, India’s national highway network was approximately 23,000 km. In 1997, national highways had a total length of 34,298 km. As of July 2013 India has multiplied thrice the distance covered by national highways (NH) connecting all the major cities and state capitals. By end of 2017, it is planned that the national highway network should be at 85000 km (12th Five Year Plan, 2012-17). Though it is an improvement in the infrastructure, we have to agree that there are many cons in the process. The highways have brought concentric expansion and appearance of sub-centers all along major road intersections. The land-use changes caused by these highways have converted the metropolises to megalopolises, hamlets emerging to bigger cities. The highways are aimed to provide better transport and to link one place to another in a fast mode. “You can start with land use, or you can start with transportation; in either case, the basic feedback leads inevitably to a hierarchy of central places and transportation links connecting them” [Moore and Thorsnes, 1994].
