The project was started by the Kerala government on the basis of a study conducted in 1993 by the National Transportation Planning and Research Center, Thiruvananthapuram. Later, the center recommended measures to reduce traffic congestion on the national highway and increase tourism opportunities. Finally, in 2017, the government approved the alignment prepared by National Transportation Planning and Research Centre (NATPAC). The Coastal Highway project is being implemented in three phases by making the existing national highways and state highways a part of the project and by constructing new ones. The Kerala Road Fund Board (KRFB) will be constructing the 468 kilometres of highway. The work on 120 km of the remaining 155 km will be covered under the Bharatmala project, which is initiated by the National Highway Authority of India (NHAI) to connect important coastal areas and ports in the country. Work on the remaining 35 kilometres will be done as part of other projects.
