The Konkan Railway Project is a 760-kilometer (470 mi) long railway line along the western coast of India. It connects Mangalore in Karnataka to Roha in Maharashtra, passing through Goa and Kerala. The project was completed in 1998 and is one of the most challenging railway projects ever undertaken.
The Konkan Railway Project was conceived in the early 1960s to provide a rail link between the Konkan region of India and the rest of the country. The region was previously isolated from the rest of India by the Western Ghats mountain range. The project was approved in 1974 and construction began in 1982.
The Konkan Railway Project is a major engineering feat. The line passes through some of the most difficult terrain in India, including the Western Ghats mountains and the Arabian Sea. The line also passes through several rivers and estuaries. The project required the construction of 12 tunnels, 17 bridges, and 100 viaducts.
The Konkan Railway Project has had a major impact on the Konkan region. The line has opened up the region to tourism and trade. The line has also provided employment to thousands of people in the region.
The Konkan Railway Project is a major achievement for India. The project has demonstrated India’s ability to undertake complex engineering projects. The line has also helped to improve connectivity between the Konkan region and the rest of India.
The other options are incorrect because they are not states that are part of the Konkan Railway Project.
