The new proposal, mooted by the Roads and Bridges Development Corporation of Kerala (RBDCK), is a 507-km access-controlled high-speed corridor linking the north and south of the state. This is expected to shorten journey time from end-to-end to 5 hours instead of the 15-20 now. The pro-Left Kerala Shastra Sahitya Parishad though isn’t impressed, calling it " anti-environment and a case of lopsided development". The pro-Jamaat Islamia Solidarity Youth Movement activists too are out on the road, flexing muscles at proponents of "the diabolic highway that will benefit the rich at the expense of the poor".
